Wikimedia Foundation | Lead Product Manager, Security | REMOTE (US + 18 countries) | Full-time
I lead the security and safety team for Wikipedia, at the Wikimedia Foundation. I’m hiring a product manager to lead our security roadmap and steer the priorities of our security engineering team.
It’s a high-pace, shipping-heavy time for the whole project right now, as we are dedicating ourselves to surviving all the ways AI is messing with us and the internet, and getting to the other side of it. I joined myself about a year ago, and have found it to be a great time and place to swing big and surprise people.
This is a PM role and PM background is certainly helpful, but it’s not strictly required (everyone has the first PM job at some point). A technical background and security expertise are a must for this role, so we’re also open to people in engineering roles, who have demonstrated PM-relevant skills and are interested in making a pivot.
Working for Wikimedia would make me actually consider moving back to the USA for the opportunity.(I'm in Japan for reference.) I previous contributed to Mediawiki and the extensions ecosystem for about a decade.
I‘ve been considering applying at WikiMedia for a while now, but [my country] is not in the listed countries. Is there a chance you‘ll expand this list in the future?
Ah, that is too bad. It's certainly always possible the countries list could expand in future, but it's not something I have insight into and unfortunately can't give you too much to go on.
We're building a system that represents domain knowledge as modular probabilistic models — making analysis rigorous and transparent. Users can connect these models flexibly into larger structures. The system enforces consistency across them, and propagates uncertainty through each step. Our first applications are in finance and scientific research, with use cases ranging from equity valuation and distress monitoring, to particle physics.
We're hiring for the following openings:
* Engineering Program Lead
* Backend Software Engineer
* Quantitative Modelling Engineer
* Bayesian Software Engineer
* Program Synthesis Engineer
* Analytic Learning Algorithm Researcher
* Product Managers and Business Development
* Domain Experts - Valuation, Quantitative Default-Probability, or Interest Rate Prediction Models: to collaborate on use cases, from opportunity validation through production
We’ve recently released a series of recordings from one of our quarterly team retreats, to share a look into how we work, and some of the technical problems we’re solving. A few team members sat down and talked through these topics, unscripted, and real. If you consider applying to join us, they offer a glimpse into our culture, and what working with us is really like.

Endless Access | Engineering Lead | Hybrid NYC | full time | 150k-250k
We're a mission-oriented org focused on bridging the global digital divide. Key to our strategy is our community game-making program: guiding learners to move from playing games to creating them. We're hiring a tech lead for our learner community platform.
This is a true tech lead job: making calls about implementation, holding the standard, owning the shared delivery plan. You'll partner with a product lead on strategy, and with an engineering manager for roadmapping & delivery. You will also work hands-on in the codebase. We're a small team (about 40) and everyone is hands-on.
There's a unique org structure at play here: Endless is a multi-pronged organization, and two of them share the platform. So the role has one foot in each organization - the hiring entity is Endless Studios, and most of the engineers work at Endless Access. You'll collaborate with passionate, brilliant people on both sides of the house.
I don't refer; apply directly at the link above. All applications are reviewed by a human.

* Infrastructure Engineer (engineering and corporate infrastructure, 50-90k)
* Customer Success Engineer (50-90k)
We make robots that autonomously construct buildings, starting with bricklaying.
There's a lot of vapourware in robotics, but we're deploying robots across multiple concurrent sites today - and generating revenue. In the last couple of months, our robots have built affordable social housing, health care living units, canal walls in the historic city centre of Amsterdam, and a youth sports centre. Help us to build things that matter in the long run.
We're looking for experienced software engineers for many roles. You can help us solve problems like:
- Data sync and analytics queries across a fleet of robots (that can be offline for hours at a time)
- Modelling buildings in code and finding the right UI for operators to edit them
- Designing systems for robots to drive safely and fully autonomously around a building site
We're rapidly scaling up operations - we'll be building in the UK soon - and we need experienced engineers who can build the systems that manage all of that complexity. If you think that 'full-stack' could reasonably mean debugging firmware, mixing buckets of mortar _and_ writing React components, we are looking for you. Robotics experience not required!

Yeah The Who's hiring format isn't a perfect fit for how we have it structured. In general, engineering can hire remote first if there's a good fit, and we have local entities or EOR processes for every EU country (to the best of my understanding)
Going through the engineering job posts but they seem to be all in the US. I'm the main maintainer of a popular OSS project using WebAssembly and want to stay in this area (OSS, C, WASM etc.). Looking at "Staff Engineer - Edge Protocols" because of the good overlap with my latest experience. Is this available in Europe as well?
Spanish National Cancer Research Centre (CNIO) | Madrid, Spain | HYBRID | Senior Scientific Computing Engineer | Full-time
CNIO is one of Europe's leading cancer research centres. We're looking for a senior scientific computing engineer to join the IT, Scientific Computing and AI area and take ownership of the infrastructure behind our research, from genomics pipelines to AI models. You'll be the senior scientific computing person in the area, reporting directly to me (the area head), and you'll help define where scientific computing at CNIO goes over the next few years.
What you'll do:
- Shape the roadmap for scientific computing at the centre and drive it forward
- Own and evolve our HPC cluster (Slurm): scheduling, monitoring, capacity planning, user support
- Build out our GPU / AI infrastructure as the centre's ML workloads grow
- Work with researchers to turn their analyses into robust, reproducible pipelines and tools
- Optional: co-author research papers
What we're looking for:
- Several years running Linux HPC environments in production (Slurm or similar)
- Comfortable with automation (Ansible, Python), containers (Apptainer/Docker) and workflow managers (Nextflow, Snakemake or similar)
- Someone who wants to set direction, not just keep the lights on
- Bonus: Ceph, Kubernetes, GPU stacks, a bioinformatics background
Key requirements: Up to 50% time can be mandatory travel for on-site in-person training sessions, very variable across the year. But no requirement to work in the office. Corollary to that - fluent or very good spoken English level is required. (PS: in actual practice it's about 1-2 work weeks every 2 months or so, irregularly)
Harmonic is a telecom hardware vendor. We are making hardware for the DOCSIS cable, PON fiber and mixed deployments.
Technical Trainer specialist is responsible for the presenting to the customer (MSOs) technical specialists, field technicians etc. the full overview of all possible product offerings by Harmonic, the full technical overview of every possible deployment (depending on the client's requirements) and full configuration for all hardware involved, including 3rd-party hardware. So no debugging and accessing code is needed, but if anything is customer facing, it must be explained.
As a brief example:
- Configuration for the DOCSIS core;
- Configuration for the PON core;
- Video streaming config;
- Network L2/L3 switching configuration for multiple vendors;
The other half of the responsibilities is creating training materials, both text and graphics (designer is assisting our team too). Recording live narrated sessions too.

We are a small boutique consultancy and are quite experienced. A lot of us have extensive consultant experience. You will join a small, highly skilled remote team of engineers and transformation practitioners working at the forefront of enterprise AI.
We use AI for both development and in our solutions. We are looking for engineers that are critical thinkers, understand the limitations of AI but also where it can have a positive impact.
Rust developer/software engineer at NLnet foundation in Amsterdam
You will join the team responsible for the development and operation of the (Rust based) backend through which we administer our open source grant programmes, and which integrates with our website.
Springcraft | Manufacturing Engineer | On-site in Palo Alto, CA | Full time | $120k–$190k + equity
Springcraft is building the platform for physical AI.
Today, building robots and intelligent machines means navigating fragmented tools, incompatible hardware, and closed ecosystems. It takes too long, costs too much, and locks builders in. There is no default platform for physical AI. We're building it. Springcraft brings together purpose-built hardware, developer tools, and AI models into one open, integrated system so that builders can create machines that sense, understand, and act in the real world.
As the first manufacturing hire, you'll own how our hardware gets made, from first builds through volume production. This is a foundational, hands-on hire. You'll be on the bench and at the machines, partnering directly with our hardware engineers. You'll build the manufacturing function from zero and lead it as the company grows.
Crossref | Head of Infrastructure Services | REMOTE | Full-time | 120k USD or local equivalent
I'm the Director of Technology at Crossref and I'm looking for a Head of Infrastructure Services to join my team. This role will lead the strategy and evolution of Crossref's infrastructure ecosystem, own the infrastructure roadmap, and lead and develop our Infrastructure Services Team.
Crossref is a not-for-profit organisation that runs infrastructure that connects thousands of scholarly publishers and millions of research outputs, serving an increasingly diverse set of communities across scholarly publishing, research, funding, and beyond. Our system is a complex mix of legacy and modern components, some parts over 20 years old and tightly coupled, running on AWS with Terraform, Java, Clojure, Elasticsearch, and PostgreSQL. You'll play a key role in our efforts to modernise this system into a set of more loosely connected services.
We're looking for someone who's as comfortable getting into the weeds of cloud infrastructure as they are leading a team. If you've grown from a strong technical background into leadership, and enjoy using your technical expertise to help a team do its best work, this could be a great fit for you.
This role is fully remote, we are hiring globally, but we will need at least 2 hours overlap with European timezones.
We're a Dental Support Organization running 65 practices across eight states. Dentistry doesn't sound like a technical job, but the platform behind it is: we've built our own operations system (Rails 8 + React, Electron, Go, and C#/.NET against OpenDental, all on AWS) and we're pushing hard on automation and AI to make the practices run better.
The team is small and developers own problems end-to-end. You'll figure out why a billing workflow breaks down, design the fix, ship it, and hear from the office manager who uses it the next week. Recent work includes an AI-first metrics layer that answers operational questions in chat, automated patient scheduling and communication, insurance verification scraping, and a live PMS integration across every practice. The domain is wide (clinical workflows, payroll, patient comms, revenue cycle) and there's a lot of novel work left once you learn the business. Big emphasis placed on being able to sit down with non-engineering team members and understand their workflows and build software to make it better.
Good fit if you want a stable company, a small team, broad latitude, and work that visibly matters to the people using it. We're actively building new features, not just maintaining what exists, so there's a healthy mix of greenfield work and improving a platform that's already in daily use by our nearly 1,000 employees.
Must reside in the US and be authorized to work in the US without sponsorship.
Confido Legal builds payments infrastructure for the legal industry. We're hiring a senior engineer to design, build, and maintain our software — leading architecture and product design, and translating business requirements into technical specs.
This is a broad, high-ownership role on a small team: you'll ship and maintain features end-to-end, lead architecture discussions, write clean and testable code, build automated E2E tests, do code reviews, and participate directly in company strategic planning. You'll also work closely with marketing and sales to keep technical work aligned with the business.
Stack: TypeScript everywhere, React + Next.js (mid-migration to Next.js), AWS with Pulumi IaC, Docker/ECS, GraphQL API, Figma (engineers participate in UI/UX).
We're looking for an expert in three or more of these (TypeScript required) with 3+ years of engineering experience.
Trax | https://www.traxtech.com/ | Onsite Cebu PH, Remote Costa Rica, Remote US are possible | Full-time | Architect
I work best as a team - with someone who can challenge my assumptions and bolster my weaknesses. I'm looking to increase the bandwidth of the architecture function at Trax, as I can't do it alone!
We BOTH need to be strong in:
- Communication - we lead by influence, not by authority. Kindness is required!
- Ego-free problem solving - good ideas come from anywhere.
- Reliable software designs - things that work on dirty data, incomplete testing, and AI-enabled development workflows.
- Building the first prototype in an area with zero guidelines - careful choices and evaluation of vendors, setting an example to follow.
You should be strong in:
- Angular, Vue, Javascript, and web serving best practices for development organizations for long term health.
- Developer enablement and tooling in the Node.js ecosystem-shared component architectures, design systems, etc.
- Data-heavy applications and their operation and security needs.
I am strong on the infrastructure, DevOps, k8s, and backend and data stacks. So don't worry about relative weaknesses there, though you will need some understanding.
This would be a good first architecture position for a Staff or Senior Staff level full-stack technical leader who wants to expand their scope. My email is in my profile!
Tandem Health | Engineers, PMs, Designers | On-site in Stockholm, Sweden | Full time
At Tandem Health we're building a clinician copilot to allow clinicians to focus on care rather than administration. We’re building, launching and iterating quickly, and are rolling out across some of the largest care chains across Europe, including most of the NHS.
Our first product listens in to the patient-clinician encounter to generate medical records, allowing clinicians to save 5-10 minutes per patient. We're rapidly expanding our product suite now, with medical coding and clinical decision support out today, and more products on the way.
We’re expanding our Stockholm team with exceptionally driven builders in a wide range of roles. Especially on the lookout for Product Manager, Head of Product Design, and Director of Engineering.
We're a small IT consulting firm working in federal and other regulated environments. We're building a reusable Terraform module catalog: versioned, tested, documented modules published to a registry that other teams consume, across cloud, container, and virtualization environments. Module and platform engineering, not one-off deployments.
You'd own the standards: module interfaces, validation, testing, releases, deprecation. Small team, no layers, and real influence over how we build. Growing, with room to move into broader platform ownership or technical leadership.
Looking for someone who has built and maintained a shared module library other teams actually used. Semantic versioning, automated testing, input validation, policy compliance checks, CI gates. Production experience with AWS, Azure, GCP, or OCI.
Multiple positions. US citizenship required (federal contract). No visa sponsorship.
We're looking for Python backend engineers to work on a trustless supercluster of performance-proofed GPU-enabled sandboxed docker container runners controlled by truly decentralized algorithms (not just PAXOS or RAFT).
Wow, that was a mouthful...
If you found it interesting, join Reef Technologies and tackle complex technical challenges like this on your own terms:
- Contribute from wherever you like; we are fully remote
- Set your own time commitment, as long as it's at least 30h per week
- See how we work in our handbook: github.com/reef-technologies/handbook
- Influence the way we operate through our Sociocracy 3.0 decision-making process
Salary on a B2B contract:
- 45-70 USD or 180-280 PLN per hour
- Flexible work schedule (as measured with a time tracker)
- We automatically adjust rates based on inflation twice a year
We're looking for someone with 5+ years of programming experience, including at least a year with Python (including open-source and significant personal projects).
Edit: If you applied and haven't heard back, please check the spam folder of the email associated with the GitHub account you used to apply — our replies sometimes end up there.
A brilliant entry!
it’s a shame I was just a bit short on the age requirement. 4 instead of 5.
It would have been interesting to take the tests – I reckon they’d have been quite cool, given the design of the entry and the fact that I’d made it through to the test stage!
MIRA | Firmware Engineer | San Francisco, CA | ONSITE | Full-time
MIRA builds lightweight AI glasses that act as a second brain: they remember conversations, answer questions in under a second, translate 60+ languages, and surface useful context through a private display. We recently sold out and shipped our first batch, and have raised $6.4M from General Catalyst, Naval Ravikant, Pillar VC, and others.
We're hiring a firmware engineer to work close to the hardware across C/C++ or Rust, RTOS, BLE, embedded Linux, microcontrollers, sensors and audio pipelines, power optimization, device communication, and low-level debugging. We're looking for 3+ years of software or firmware engineering experience and a track record of shipping complex technical products end-to-end. Consumer hardware and early-stage startup experience are strong pluses.
This is a full-time, in-person role in San Francisco. We can't provide current or future U.S. visa sponsorship.
Artificial Analysis | San Francisco & Melbourne | On-site | Full-time | No visa sponsorship
Artificial Analysis is the leading independent AI benchmarking company. We evaluate frontier language, image, video, speech and hardware systems across quality, speed and pricing. Our work is used by AI labs, engineers, enterprises, investors, policymakers and major publications to understand how the frontier is moving.
We’re a team of 40+ and expect to roughly double this year. We’re hiring across:
- AI/ML and research: Senior AI/ML Engineer; Members of Technical Staff focused on applied AI research, language-model evaluations, inference, speech, AI hardware and robotics
- Software engineering: Senior Full-Stack Software Engineer working with TypeScript, Next.js, PostgreSQL/Supabase and data visualization
- Forward-deployed engineering: Language Models and Media Generation
- Product: AI Hardware, AI Speech, and Image & Video Generation
- Commercial: Technical, client-facing MTS roles for people from strategy consulting or technical/startup backgrounds
- Operations and recruiting: Business Operations Manager and Senior Technical Recruiter
You’ll work directly with frontier models and the organizations building them, help define how AI systems are evaluated, and publish data and analysis used across the industry.
Important: these are in-office roles in San Francisco or Melbourne, depending on the role. We are not hiring remotely and cannot sponsor visas. You must already have authorization to work in the US or Australia.
Roles and applications: https://jobs.ashbyhq.com/artificialanalysis
Akkio builds the AI platform the world's largest media agencies (Havas, Horizon Media, and others) use to run campaign workflows in production: audience building, media planning, measurement, and campaign analysis. Agentic workflows plus traditional ML, deployed on-premises inside agency cloud environments, directly on top of their data. We're ~50 people, past PMF, well funded, and growing revenue quickly.
We build agentically by default. Every engineer directs coding agents daily, and we're actively rebuilding our SDLC around that — not piloting it, not debating it. If you've felt that shift and want a team that's all the way in, that's us. We also run flat, so "senior" means ownership, not management layers.
Three roles, all $160k–$240k + equity:
* Forward-deployed engineer (FDE) — Python, TypeScript, true generalist. You embed with agencies whose systems steer billions in media spend and build whatever the problem needs: integrations, agent workflows, backend services. What you build in the field becomes product. Regular travel.
* Full-stack (web) — Vue.js, TypeScript, Node.js. You've run projects, guided architecture, and survived framework upgrades and large refactors. You care about the experience analysts live in every day.
* Backend — Python. Interesting work in at least two of: LLM systems and code generation, statistics, traditional AI/ML, large-scale data processing, distributed systems.
Modern hardware supply chains run on spreadsheets, email, PDFs, and prayer. It's like fax woke up in 2026. We're fixing it with an AI-first procurement platform for aerospace, defense, and nuclear manufacturing - customers include Machina Labs, Astranis, K2 Space, Castelion, and Antares.
At SmallSat last month, a supplier walked up to me (in a full spacesuit costume), said "oh you're from Silkline, we love you guys!" and handed us a roadmap item on the spot. That's the job: sit with customers, hear what's broken, ship it. 0-1 product, real UI/UX ownership, ERP integrations that sync POs and manufacturing data.
Stack: TypeScript, React, Next.js, GraphQL, Trigger.dev. You: 5+ years full-stack, startup or 0-1 experience, fast with APIs (bonus: ERPs). The role touches ITAR-controlled data, so US persons only, no visa sponsorship.
We 5x'd our customer base this past year and continue to grow fast. Small team, direct line to the founders (Isaac and myself). Also: space-suited mascot named Silky.
At Statecraft, we are building an AI workforce to help automate the US government. Currently our government is operated almost entirely by consultants who outnumber public servants 3:1 and institutionalize inefficiency so they can bill more hours. This only leads to agencies struggling to meet their missions, overworked and underpaid public servants, and overburdened taxpayers.
Most of what these consultants do is easily automatable: data entry, basic spreadsheet work, filling out paperwork, etc.; we do this with AI and save taxpayers ~80% on average while completing the work ~10x faster with 2-3x less errors.
We're a small, lean, mission-driven team and hiring Forward Deployed Engineers to build use cases and integrate deeply with agency customers. You'll be working with critical systems, massive surface area and national impact.
* This position requires U.S. citizenship and the ability to obtain/maintain a security clearance.
Axmed | AI Engineer | REMOTE (preferred Spain, UK, Poland, Romania) | Full-time | apply: axmed.teamtailor.com/jobs/8175859-ai-engineer
Axmed runs a live B2B marketplace connecting healthcare providers in low- and middle-income countries with pharmaceutical suppliers, working to make sure geography and income never stand between someone and the medicine they need. Backed by the Gates Foundation and Founderful. We're past proving it works and into scaling it — this role is what takes us there.
You'll design and ship autonomous agents that run real steps of the marketplace (sourcing, quoting, order matching, supplier follow-up) on real transactions and real money, with a human in the loop where risk demands it. Full lifecycle ownership: you decide the approach, build it, ship it, watch it, fix it.
Stack: Python, your choice of orchestration framework (LangChain/LangGraph/LlamaIndex/CrewAI), LLM APIs, cloud infra, CI/CD.
We are a fully remote, global team of 55. No visa sponsorship/relocation.
Attendi | Machine Learning Engineer | Amsterdam, Netherlands | ONSITE (hybrid) | €6,000 - €7,000 per month | Full-time (80–100%, ~4–5 days/week) | Visa sponsorship + 30% ruling possible
Company: Healthcare professionals spend too much valuable time on administrative tasks while they should be using that time delivering great care. Attendi enables healthcare professionals to report through speech. Aside from saving time, it removes the screen between client and caregiver, allowing more personal and effective care. Burdened by an aging population, the healthcare sector is in desperate need of innovators like Attendi. We provide an extraordinary work environment: getting paid well to work with smart people on things that actually have a positive impact on society.
Role: As an ML Engineer, you will accelerate our roadmap through operationalisation of ML in real-world production systems, owning the full lifecycle from prototyping to training, serving, monitoring, and continuously improving models in the cloud. We pride ourselves on keeping teams small, tightly knit and agile, enabling us to build the next generation of reporting intelligence for health care professionals.
Suitability: Hands-on experience/responsibility in an ML role. Full-stack with exposure to ML is not suited for this position.

Happy to share more details with qualified candidates. Thanks for reading.
Hi all, I’m Yuriy, founder of Puma.tech. Prev. worked at Cloudant (YC S08), Meteor (YC S11), Parse (YC S11, Facebook/Meta), and explored AI/ML (computer vision for self-driving cars).
We have 2 products:
1. https://PumaBrowser.com: iOS & Android mobile browser with built in LLMs & wallets. 1m+ downloads.
2. https://PumaAI.com: small research lab focused on building private local/hybrid alternative to ChatGPT.
Open Roles: Eng (iOS/MacOS, Android, Ai/ML, Browser Extensions), Based Social Media Intern; Internships: Eng, Design, Growth
We’ve raised a few rounds from some of the best builders in ai and crypto:
Protocol Labs (YC S14), Chris Larsen (Ripple), Anatoly Yakovenko (Solana), Illia Polosukhin (NEAR Protocol), Sridhar Ramaswamy (Snowflake CEO), Jason Warner (poolside.ai, ex-GitHub CTO), Don Ho (Orange DAO, Quantstamp W18), Evil Rabbit (Vercel), John Phamous (SF Compute) and other amazing builders.
How to Apply: email careers+hn [at] puma.tech with your GitHub, a note on what you're most proud of building and what you'd like to build next.
apologies, we've got a lot of ai-generated applications in the last few months so might have missed it. mind bumping the thread and mention `html5cat` and i'll make sure we look into it?
found your thread – your email covers things you did, but nothing about "why Puma" or other simple questions we ask. seems like one sided, generic mass application. impressive background, but didn't seem like you care about what we're building.
1. I received a question about my schedule (meaning: no other questions asked), I answered and received no further response.
2. I applied using your own template {a note on what you're most proud of building and what you'd like to build next}. My application was absolutely not generic mass application
3. I sent you several things I’m proud of. Among them were:
- my open source contributions to p2p (torrent network) libraries. I did this because you have IPFS (which is p2p network) in browser.
Your application template does not contain "why Puma?" question, but spending my own time on these 2 things (local-first browser, p2p) and including them in the application was, I believe, a pretty clear answer to it.

Responsibilities: productionize novel steganography models, build inference pipelines, integrate models into cloud platforms, benchmark performance, and turn research into maintainable production code.
Required: PyTorch, ONNX export, experience deploying deep learning models to the cloud, Python and C/C++, strong cross-team communication.
Bonus: background in steganography/watermarking/media provenance, video/image codecs, MLOps tooling, CV/ML publications or open-source contributions.
St. Jude Children's Research Hospital | Sr. Staff or Principal Software Engineer, Rust Genomics Infrastructure | Memphis, TN | ONSITE (2x/week onsite) or REMOTE | $125,840 - $238,160 | https://www.stjude.org/
St. Jude Children's Research Hospital is hiring Rust software engineers to rebuild the genomics ecosystem in Rust. We work at the intersection of computer science and genomics, and we're trying to build a better foundation upon which genomics can be done using Rust. The primary project we’re working on is a bioinformatics workflow execution engine for local, HPC, and Cloud called Sprocket (https://github.com/stjude-rust-labs/sprocket). You can also check out the other projects we have going on at https://github.com/stjude-rust-labs.
NOTE that prior experience in bioinformatics or biology is NOT required for any of the positions below. You must be interested in learning though! If you'd like to get a sense of what you'd be learning, check out the guide we wrote to teach software engineers about genomics here: https://learngenomics.dev.
I’m a co-founder of Quill, a fullstack SDK for adding customer-facing analytics & data features to your app. Backed by YCombinator & top-tier SV-based investors (fundraising not publicly disclosed; happy to share any details when we chat).
Some examples of how customers get value from Quill:
• pre-IPO fintech adds custom reporting & data export features to their money movement product.
• Series B healthtech is now able to deliver completely custom in-product reports & dashboards to every enterprise customer they onboard.
• Series A govtech adds analytics and reporting capabilities within their existing agent/chat product.
Reasons you’d love working with us:
• Work with a small, focused, talented team on a highly technical product (by developers for developers).
• Funded company in a big market, but still prelaunch with a team size <5
• High level of product ownership with tight feedback loops: the products you build are shipped quickly and get used by real customers immediately. Our latest hire built our entire CLI product from 0 -> 1, and it was used in production by customers the day it shipped.
We are growing the team to keep up with demand for new features that our customers are asking us for, while also preparing for launch. We're looking for someone that will make us better. We’re just getting started, and want you to bring your opinions, expertise, and experience to the table (not just execute on the ideas we already have).
Trustworthy Technology | Earth | Part Time | REMOTE | Vision, Marketing, and/or Design
Hi, we are a small group trying to bring the "trustworthy" feature back to tech. Curating and building a FOSS+ toolset, storefront, and eventually online service—all to support freedom, privacy, and informed consent—on device and on the net.
First off, you'll notice that you've not heard about this project before. Next, the message is a bit scattered, and the "programmer art," while arguably not horrible isn't winning any awards either, haha.
That's where you come in.
You are one of the few folks who really cares about this stuff, and also a graphic/product designer, or perhaps a digital marketer, communicator or "people whisperer." (Being in the EU would be helpful as well, to work from the digital sovereignty angle, though not required.)
Some of us are unemployed and currently donating our time. Maybe you are too, or retired/cashed-out and bored. Consider this another FOSS-like project. We hope the store/service will make money, but we're not there yet.
AiMi | Full Stack AI Engineer | Remote(Everywhere) | Full-time
AiMi builds agentic AI infrastructure for capital markets: autonomous agents that ingest venue and vendor notifications, assess impact across client infrastructure, and drive change management workflows in real time, replacing what used to be manual, static processes for exchanges and their ops teams. live production platform, not a pilot.
you'd work across the full stack: React/TypeScript frontend, Node.js backend, AWS Lambda. concretely: shipping features in the agent pipeline, building MCP-based connectors and skills that extend what our agents can reach, running evals on agent accuracy and reliability, building observability and alerting for agent latency/error rates/failed workflows, and making long-running LLM, agent, and SSE calls actually resilient (timeouts, retries, circuit breakers, fail-fast, recovery). also a fair amount of diagnosing dependency/version conflicts in a Node.js/npm monorepo, which is its own skill.
looking for 2-3+ years hands-on experience, solid Node.js and REST API background, real hands-on work with LLMs or agent frameworks (Mastra, LangChain, LlamaIndex, Claude, OpenAI or similar), comfortable with AWS (Lambda, Bedrock, DynamoDB, S3, Cognito, API Gateway, CloudWatch), MongoDB/DynamoDB, and genuinely tests what you ship (unit, integration, e2e). familiarity with spec-driven development (Claude Code, Cursor, CodeRabbit or similar) is a real plus since that's how we work day to day. bonus points for capital markets/trading infra background, LLM observability tooling like Langfuse, SSE streaming experience, or PostHog.
you'd be working on great things here: real architectural decisions at an early-stage company, visible impact from week one, and room to grow into a senior or lead role as we grow.
I see you're looking for a Full-Stack AI Engineer with experience in Node.js, AWS, and LLMs. Let's get started.
I'd focus on building robust, resilient agent pipelines and LLM integrations. I'd start by evaluating and improving the agent accuracy and reliability. I'll also build observability and alerting for agent performance. I have experience with LLMs and agent frameworks, and I can help ensure your LLM calls are resilient. I can also assist with diagnosing and resolving dependency and version conflicts in your Node.js monorepo. I'll bring this experience to the table, and I can share more on my approach in our next conversation.
What specific areas of your agent pipeline do you want to improve first?
Snout https://snout.com/ | Multiple Engineering + Product Roles | Remote US or Ontario, Canada | Full Time
Join us at Snout on our mission to ensure no one ever has to make a health decision for their pet based on the cash in their bank account. Snout plans pay for 100% of routine veterinary care, unlimited visits, and additional member benefits - think pet insurance, that you will actually use every year.
We're growing the team and hiring across the board. Open roles:
Full-Stack Software Engineer - Build and ship every day across our web apps, payments, and data systems, from database to UI.
Across all roles we're looking for at least three years of relevant experience, and we're hiring senior and staff level engineers as well.
Our tech stack includes Node.js, React, PostgreSQL, AWS, Tailwind, and Python. We use both JavaScript and TypeScript heavily. Our team uses LLM-based tooling day to day, but we're fundamentally a human-centric team, and our product itself does not heavily feature AI components.

We are a vibrant technology company developing groundbreaking solutions that enable the rapid transition towards a world of decentralized energy. We’re helping companies to rapidly transition from being passive electricity consumers to becoming fully self-sustaining prosumers, capable of leveraging various renewable energy assets.
We are currently looking for a Senior Rust Engineer to join one of our backend teams in Berlin.
The role is primarily based in-office in Berlin, with a possibility for hybrid work (which can be discussed during the course of the interview).
Colonist.io is a multiplayer board game platform. ~20 people, millions of monthly players, no middle management between you and the product.
You'll own features end-to-end and ship to a live player base within days. Right now we're evolving the core experience and building toward a multi-game platform. The mission is to become the internet's biggest board game platform.
This role is a good fit if you: want to see your work matter at real scale without a large team around you, are comfortable with ambiguity and don't need someone to define your tasks, and use AI tools as a genuine multiplier in your workflow.
NetBird is open source networking and access control WireGuard-based
overlay networks with zero-config peer-to-peer connectivity. Open source, built
in Europe, used by thousands of teams worldwide. We're a small and growing team going up against the incumbents in network security. Post Series A.
- Engineering Manager : You will take a huge part in leading and scaling our engineering org. Unblocking, scaling, hiring, you'll still read code and hold technical opinions that impact the product. We're not looking for a pure people manager. Networking/infra background is a plus, not a filter. If you've scaled a team from 0 to 20+ and seen your product scale too, I'd love to talk to you.
- Senior/Staff Backend Engineer (Golang) : the control plane: peer
coordination, policy and access control, multi-tenancy, and keeping it
all fast as customer networks grow into the hundreds of thousands of peers.
- Network / Client Engineer (Golang) — the agent side: WireGuard,
NAT traversal and hole punching, relays, DNS, and shipping one client
across Linux, macOS, Windows, iOS and Android. If you enjoy debugging
why one connection out of a thousand won't go peer-to-peer, this is
the role.
- Solutions Engineer — technical, customer-facing, pre/post-sales. You'll
be the person who architects a rollout for a 500-person company's
network live on a call, and a great channel back into the roadmap.
We have an office in Berlin and mostly work CET/CEST. We'd love to have you
in the office with us, but if your experience is stellar we're happy to hire
remote. We're scaling quickly, so this is a chance to join early and scale your career as well as with the company.

G-Research is a leading quant finance company. Big compute farm, interesting problems.
My team is hiring senior engineers to work on our (actually world class) DAG scheduling infra for distributing research and production workloads across the compute farm. What we do is roughly:
* maintain and improve the SDKs for that scheduler in Python, F#, and C#
* add interesting new features to the scheduler itself
* maintain and improve a web backend and UI for quants and engineers to monitor their jobs, increasingly with high availability requirements
* translate bidirectionally at the business level between low-level infra providers and quant/ML researchers
Some functional experience preferred, because our core product is in F#. Lots of dealing with very smart researchers and engineers, with the kind of fun problems arising when you run large ML workloads at scale.

Mastra | Customer Engineer | REMOTE (AMER or EMEA time zones) | Full-time
Mastra is the open-source TypeScript framework for building AI agents (agents, workflows, memory, evals, tracing). From the team behind Gatsby, YC-backed,https://github.com/mastra-ai/mastra
We're hiring a customer engineer. Some companies would call this an FDE; we don't, because roughly half the job is shipping in the framework itself. The other half you're embedded with paying customers deploying agents to production: in their Slack channels and on calls, writing code in their repos, reviewing their PRs, working through architecture with their engineers. What you learn there comes back as bug fixes, features, and new primitives in Mastra. One of our current customer engineers is among the top bug-fixers in the entire codebase.
You should be a full-stack TypeScript engineer who has built agents and who can explain technical decisions clearly to engineers who haven't seen your code.
Remote. We have a lot of EU customers and response-time SLAs, so US Eastern/Central or EU hours work best.
Process: a call with Shane (co-founder/CPO, leads customer engineering), a conversation with a customer engineer, a 2-3 hour take-home, then you present it to us and get feedback.
ORIGAMICS | Founding Researcher | San Francisco | ONSITE/REMOTE
Origamics is building AI models that reason about electronics and help turn schematics into production-ready boards.

In this role, you'll be the technical foundation our scientists, ML engineers, and software engineers build on. At the core of our efforts is an operational physical weather model written in Julia, executed on GPUs. Responsibilities include designing and operating cloud environments, deployment pipeliness and infrastructure-as-code that keep our systems reliable, scalable, and fast. Our ideal candidate has extensive experience in HPC environments with Slurm management.
We build repricing software that keeps online sellers on top of their competition on 130+ marketplaces.
You’ll work on pricing algorithms, high-volume data ingestion, marketplace integrations, scalability, and enabling our product to be used by AI agents.
We’re looking for someone with extensive experience building data-intensive web applications backed by relational databases, and who is comfortable designing, deploying, operating, debugging, scaling and evolving production systems.
Stack: Python, Postgres, FastAPI, SQLAlchemy.
Our office is beautifully located in Mauritius. We sponsor visas and handle all relocation/immigration.
Vistulo | Fully REMOTE (Poland or Romanian residents only) | B2B contract | US Eastern timezone overlap required
Vistulo is a boutique outsourcing company based in Poland. We specialize in expert-level talent for financial institutions. All roles are for work with a top North American banking client.
All roles are 100% remote, B2B contract, rates are net + VAT in PLN, long-term.
Mingla | CTO (ONSITE, Stockholm) or Part-time Engineer (REMOTE ok) | https://mingla.com
Mingla makes strangers meet at in-person events: attendees scan a QR code and are straight in — no App Store, no signup — gamified missions start real conversations, and the organizer gets proof of what happened in the room.
You'd own the platform end to end: Elixir/Phoenix backend (Ash, GraphQL, Postgres) and a native SwiftUI iOS app — the QR entry is an App Clip. We're open to two setups: a full-time CTO onsite in Stockholm, or a part-time engineer who can work remote.
Apply: hello@mingla.io, subject "HN: CTO / Engineer", with a link to something you've built and one line on which setup fits you. No cover letter needed.
Biobase has grand ambitions. We broker biospecimens, whole slide images, and the clinical metadata attached to them, on a supply-chain backbone that we're steadily automating. We’re building healthcare-data-focused agents on top of the datasets that we’re assembling, too.
We'd rather build the thing that removes the work than throw people at it. Two roles, one team, both reporting to the CPO:
Senior Technical Product Engineer ($150–230k + meaningful equity).
The product team's technical interface. Architecture decisions and code review on the platform (Python/FastAPI, TypeScript/React, Postgres, Azure); the data pipeline and informatics that take specimen, slide, and clinical data in from suppliers and labs; and product ownership of the internal platform that builds our agents (permissions, evals, cost control, guardrails for sensitive data). You've been the reviewer of record somewhere, you've operated what you shipped, and you think in business problems before tickets.
Technical Product Engineer, early career ($90–170k + equity).
Same territory at an earlier stage: the platform, the data pipeline and informatics, and the agents we run against our own operations — with a senior product engineer and our lead engineer reviewing your work and pairing when it helps. Open on background – self-taught, bootcamp, degree, research lab, a career you're leaving – selective on the bar. You've built something and someone else used it.
We build with Claude Code every day and expect you to become both fluent with it and skeptical of it. No ticket queue, no spec handed to you. Comp is salary + equity combos you choose between.
To apply: email jobs@biobase.ai with something you built that eliminated manual work and what happened after it shipped. Links over resumes, no cover letter.
Odin builds workforce visibility and compliance software for critical infrastructure. We’re deployed on 500+ active projects with 100K+ workers, securing more than $100B in construction value.
Senior Design Engineer — Own interfaces from UX and visual design through production React. You’ll establish our design language and design system, prototype interactions, and ship responsive, accessible frontend experiences. We need someone who genuinely designs and codes.
Senior Platform Engineer, Edge Systems — Build software connecting cameras, access-control readers, rugged devices, and local compute to our cloud across unreliable networks. Work includes protocols, real-time streams, buffering and synchronization, remote deployment, diagnosis, and recovery.
Senzing builds enterprise entity-resolution SDK technology — an embeddable library that runs entirely inside customer infrastructure with zero data exfiltration. We're hiring a platform engineer to own the AWS infrastructure behind Placekey (our location-data subsidiary), a production API service running at scale.
Day one, this is a cloud/platform role: you'd own the operational health of Placekey's stack, close out post-migration hardening, and have real input on where the infrastructure goes next. Over time the role grows to include internal IT and systems work (Active Directory, endpoint/laptop provisioning, Tailscale, security) — so we're looking for someone who's happy owning things end to end, not only the glamorous layer.
Stack: EKS Fargate, Aurora PostgreSQL, S3, Lambda, Cloudflare, API gateway (Kong/AWS), Terraform, Grafana/CloudWatch/Datadog. Apps are Scala and Rust.
Looking for: 5+ years platform/cloud infra, production Kubernetes (EKS ideal), managed Postgres (backup/recovery/tuning), IaC, solid networking, strong Python/Bash. You don't need to be an expert on the IT/systems side today — but you should want to grow into it.
Remote anywhere in the USA. Competitive salary, full health/dental/vision, 401(k) match, flexible PTO.
To apply: email enghiring@senzing.com with your resume and a short note — tell us about a challenging production system you've owned end to end, including an incident where your monitoring missed something and what you changed afterward.
We started off naively as just another intelligent document processing SaaS. Years of experience have shown us where the real pain points and value lies. Join my AI team and be horrified by how many critical business processes rely on email. Then help me execute on our ambitious roadmap!
If you find yourself nodding along with the following statements, you may be a good fit:
- You enjoy getting your work into the hands of users
- You’re okay debugging a stray tensor in the morning and designing services in the afternoon
- You care about the field of AI and interact with its community
- You can ‘sense’ when a loss curve is doomed
- You’ve fine-tuned LLMs, even just for fun
- You’ve been thinking a lot about agents lately, for some reason
- You don’t mind the odd bit of customer support (it’s where we get our best insights!)
All credentials welcome, including recent graduates. We’ll shape the role around you. What matters is creativity and visible engagement with the field.
Who may apply: EU citizens or holders of a Belgian work permit. (Everything else is more admin than we have time for.)

All roles require working hours that overlap with 11am-3pm ET.
Trustible | Senior Engineers (Agentic Engineer and Forward Deployed Engineer) | Arlington, VA (DC Area) | Hybrid (2-3 days in office) | 145k-165k + equity | Full Time
We're an AI Governance software company helping organizations navigate emerging AI regulation and risk. Our platform helps organizations build a high quality AI inventory, and automates various risk assessments, reviews, and compliance workflows needed for the EU AI Act, ISO 42001, or the NIST AI RMF. We're building a lot of agentic features and are looking for engineers familiar with AI engineering, or experience integrating with hyperscaler MLOps platforms.
We're looking for people who want to work on on building trustworthy and responsible AI systems.
Neon Commerce | https://neonpay.com | Senior Software Engineer | New York, NY (On-Site) | Full-time
I run the engineering team at Neon, the commerce platform for mobile games. We're working on making it easier for game developers to monetize their games. We're going after the Apple/Google duopoly by creating ways for developers to reach their players directly and avoid the App Store tax.
We're a small team, and growing quickly. We just raised our Series A and are focused on expanding to more countries, growing our commerce offering, and scaling the core product.
We're looking for senior engineers looking for full-stack, product work. The stuff you build will ship directly to our customers (game developers) and their customers (game players). There's a lot to own and manage, and you'll sit alongside a world-class team in doing so.
The best developers don't wait for a customer to tell them something's broken.
They catch it first, in the pull request, in staging, or in the checkout flow at 3am, before a single user notices. That instinct is Checkly's whole reason to exist. We give developers and their agents the tools to own reliability the way they own their code: monitoring defined as code, powered by OpenTelemetry and Playwright, versioned and reviewed like everything else they ship. From pull request to post-mortem, in one place.
Open roles:
- Product Manager (DevTools & AI Reliability) - remote UTC-3 to UTC+3
- Senior Sales Engineer - remote Europe (UTC+1 to UTC+2)
- Sales Engineer - remote US, Eastern time zone
NYC | ONSITE (hybrid) Norm Ai, the agentic law company, has a client base with a combined $30 trillion in assets under management. Norm Ai pioneered Legal Engineering, the process that empowers lawyers to build and supervise domain-specific AI agents with Norm’s proprietary suite of no-code software tools. Norm Ai technology is deployed inside many of the largest and most consequential institutions in the world. Norm Ai is also the technology behind Norm Law, LLP, a separate but affiliated AI-native law firm built for the era of agentic AI. Norm Law’s attorneys advise leading institutions across private funds, private equity, venture capital, real estate, registered funds, and financial regulation, using the same legal intelligence platform that powers Norm Ai’s products.
We're building a sensorized vibrator that actually listens: pressure and motion sensors plus an AI story made for women that changes the motors based on what her body is doing. Closed loop, not another dumb toy.
Hiring a Founding Hardware & Embedded Engineer to own sensors → electronics → firmware/BLE → DSP → body-response → motor → app, through factory. Portfolio over résumé; degrees and years don't matter. Apply with what you've built: morgan@experiencedevin.com
Reframe Systems | Boston, MA | ONSITE or HYBRID | Full-time
We're creating housing on a mass scale through a network of robotic microfactories producing highly-customized buildings, from ADUs and cabins through townhomes and mid-rise apartments. We build with industrial efficiency while making buildings for an exact footprint, scale, style, and level of finish to fit any market, regardless of how tight the site or the zoning.
The core software problem is producing buildings designs without the typical months of design development and engineering. You can design natively in our building system or import existing designs, taking in a high-level architectural schematic and using that to generate a detailed manufacturable 3D model of the building (every stud, sheet of OSB, nail, electrical outlet, etc.) used to drive professional engineer review, permitting, and production. A compiler for a building.
Xaira Therapeutics | Midlevel/Senior/Staff Engineers | Seattle or SF
Xaira Therapeutics is developing biological foundation models (not LLMs) to hit undruggable targets and cure disease. We've put together an incredible cross-disciplinary team of pharma veterans who have brought drugs to market, drug designers/AI scientists from Nobel laureate David Baker's lab, and engineers from tech in order to meet the moment and build a company to reimagine how drugs are made in the pursuit of better medicines. We're not a SaaS company, and the ultimate goal is to see the medicines we make delivered to patients.
I lead the engineering team and am hiring across multiple teams. There's:
- Research Engineering: work on a modeling team with the goal of making a model better. You think in tensors, understand what makes a kernel fast, and obsess over training throughput.
- X-Scientist: building an agentic copilot for drug development with access to our internal suite of tools. You have backend experience, have built tools for agents to interact with, and enjoy tinkering with agent harnesses.
- Data Engineering: we generate large volumes of data from our lab that provide critical feedback loops to our modeling efforts. You either hate or love lakehouses, have a preferred ETL orchestrator, and are intrigued by the problem of capturing data off of lab instruments.
- ML Platform: boy do we have some GPUs for you. Modeling teams need productive compute infrastructure, job scheduling, and numerous other affordances so that they can "just focus" on the model. You shudder at the words "falling off the bus", you have an opinion on how checkpoints should be recorded, and you've built tools that improve the modeling lifecycle.
Send me an email to apply: justin.yan@xaira.com
Include a resume and tell me about something you've built that illustrates your skills.
Legile | Senior Full-Stack AI Engineer (CTO track) | Antwerp, Belgium | HYBRID | Full-time | Belgium-based only
Legile builds OneView, a legal AI platform that legal teams use in production for contract review, risk and compliance. We recently joined the Anchr software group and are scaling from proven MVP to production-grade platform.
You join as the third person in the team, next to the two founders, and take technical ownership of OneView: retrieval (PostgreSQL/pgvector), LangGraph pipelines, FastAPI backend, React/TypeScript frontend, plus the CI/CD and observability that let a small team ship with confidence. As the team grows, the role grows into CTO.
We care more about AI-native workflows you have shipped to real users than about ticking every box on a stack list. Real R&D backed by a Flemish innovation grant (VLAIO).
Snowflake | Forward Deployed Engineer, Product Manager | Menlo Park, CA | Warsaw, Poland | London, UK | ONSITE
I’m part of Snowflake’s Applied AI / Forward Deployed Engineering team, and we’re hiring for multiple roles on the team.
We work directly with strategic customers to design, build, deploy, and improve production AI systems on Snowflake. That includes LLM applications, RAG and agentic workflows, evaluation frameworks, guardrails, observability, and production iteration using Snowpark, Cortex, and Snowflake’s native AI capabilities.
For the FDE role, we’re looking for strong engineers who can build and ship customer-facing AI systems end to end, especially if you’ve worked on LLM apps and care deeply about evals and quality. For the Senior role, we’re looking for someone who can lead multi-engineer AI engagements, mentor other engineers, and still be hands-on in architecture and implementation. The roles are customer-facing and involve travel, including at least 25% onsite time with strategic customers.
If you like working in ambiguity, building real AI systems instead of demos, and partnering closely with customers to get things into production, these roles are a good fit.
At Middesk, we're building the business identity infrastructure that banks, fintechs, and platforms rely on to know who they're doing business with — powering KYB (Know Your Business) compliance, fraud prevention, and entity verification at scale.
We're expanding beyond verification into a full agentic compliance platform — orchestrators and specialist agents that automate what used to be manual compliance review. Backed by YC, Sequoia, and Accel (Series B).
We're a small, sharp team with high ownership — engineers work closely with customers and leadership, and get to see their work ship fast.
Greenzie | Robotics Software Engineer (Early Career + Experienced) | Atlanta, GA | ONSITE/HYBRID | Full-time | https://greenzie.applytojob.com/apply
Greenzie builds the autonomy software that runs on commercial mowers. We don't sell the iron — Wright, Mean Green, Bobcat, and Greenworks Commercial do, with our stack on them. Mission is to free humans from repetitive outdoor labor. The software is on hundreds of machines in the field today.
We're hiring roboticists who want production robots doing real outdoor work, not lab demos. C++, Python, ROS/ROS2. You will own (or learn) a subsystem, debug messy field data, and ship to machines that mow for a living.
CoVar | Durham, NC and McLean, VA | https://covar.com/ | Full-time | HYBRID (3 days in office per week)
CoVar is a small R&D company specializing in AI/ML and software development for defense and healthcare. Bootstrapped and profitable. We're looking for a jack-of-all-trades who can: prototype computer vision algorithms, build Python web services, wrangle large sets of data from disparate classes of sensors, ... any or all, with the only hard requirement being eagerness to learn.
Visit covar.com for more information on our current openings!
Darn, I applied to y'all for the Durham location in July but got a rejection after a week. I wonder if my resume - which I've tweaked since - was the issue. Wonder if it's worth applying again?
I’m the Head of Engineering at Starlight, and we’re hiring a senior full-stack engineer.
We build software that helps financial institutions connect people with government benefits they’re eligible for. More than $100B in benefits go unclaimed every year because the underlying systems are fragmented and difficult to navigate. We’re trying to change that.
Our engineering team is intentionally small, so this is a high-ownership role. You’ll work across the stack, help shape our architecture and engineering culture, and have significant influence over how and what we build.
One area I’m especially excited about is building an “AI-first” engineering organization. I put that in quotes intentionally because I don’t think the industry has figured out exactly what it means yet—and neither have we. I want this person to help me figure it out.
I’ll encourage experimentation and use of AI, and we’ll have lots of conversations about what works and what doesn’t. But I’m not setting token quotas or mandating that people use AI for everything. I care much more about figuring out where it genuinely makes us better.
I’m actively involved in the hiring process and happy to answer questions about the team, role, or company.
We're building out our NYC-based API platform team as our API-based business rapidly grows. We're a European -based company, so you'll enjoy the best of both worlds with competitive compensation, 30 days of PTO from day one (your manager, me, will make sure you use them all) "work from anywhere" days, addtional compensation for on-call shifts (including additional time-off if you actually have to do something after hours)
Rootly | https://rootly.com/ | design, engineering, GTM, sales | SF Bay, Toronto, APAC
Rootly is an AI-native on-call and incident response. Modern Slack and MS Teams native incident management—from your first alert to retrospective. Trusted by 100s of leading companies including NVIDIA, Squarespace, Canva, Grammarly, Elastic, Tripadvisor, and Figma.
Hiring across design, engineering, GTM, and sales https://rootly.com/careers#open-roles
One of these roles (TPM) looks like a good fit for me and I have a customer perspective as my previous company had Rootly. Is there a referral code I can use? Forgive me, this is my first post in these career threads.
VLM Run (https://vlm.run) | 1x Founding Infrastructure Engineer
We’re building the inference platform for visual intelligence. We’re a deeply technical team of veteran AI / computer-vision engineers (20+ years combined, MIT/CMU PhDs) who’ve shipped production ML infrastructure across autonomous driving and LLMs.
We just launched the VLM Run Gateway (https://vlm.run/gateway), a unified API that serves open-weight VLMs, embodied VLAs, ViTs, served across a fleet of GPUs and clouds. That's exactly the infrastructure problem this role will own.
If you’re interested, email us at hiring@vlm.run with your GitHub profile and link to projects you’ve recently built - especially with docker, k8s, GPUs.
Robotics and AI Institute | Software Engineering Intern | ONSITE (Zürich, Switzerland) | Internship | No visa sponsorship
We're hiring some robotics systems software focused interns in our Zürich office. We're specifically looking for late stage masters students with strong software engineering fundamentals and some skills in turning math into performant code. We have two tracks available, either offline training infrastructure for RL (physics simulation, gaussian splatting, RL algo implementation) or on-robot deployment (online inference, fast C++).
The software team in Zürich is involved in building the tools that accelerate research, while having a close connection to what the researchers are doing.
We're looking for people who already have the right to work in Switzerland. That means Swiss/EU/EFTA citizens, or those with a work permit in Switzerland already.
Black Canyon Consulting (BCC) is hiring Platform Systems Engineers of all levels to join our team at the National Center for Biotechnology Information (NCBI).
Our team is dedicated to building cutting-edge tools and systems. Our mission is to empower developers across NCBI to build, deploy, and manage software, data, and web services that make a real difference in the lives of millions of Americans.
Your contributions will play a crucial role in modernizing government technology infrastructure, fostering innovation, and ultimately making a tangible impact on communities across the country and globally. This is your chance to be part of a mission-driven team that’s shaping the future of digital government.
Tech: Linux, k8s, Service Mesh, Kafka, GitLab, ArgoCD, Elastic APM, Python, C++
Enveritas (YC S18, non-profit) | Backend Software Engineer | Remote (Global) | https://enveritas.org/jobs/
Enveritas is a 501(c)(3) nonprofit working on sustainability issues facing smallholder coffee farmers. We collect field data in 30+ countries and build systems for analyzing risks in coffee, cocoa, and tea supply chains (including EUDR-related deforestation checks).
Applied through the portal recently... the EUDR farm-list validation work is a problem I've worked on from the agricultural side. Happy to answer anything if it's useful to Enveritas.
Hiya's Voice Intelligence Platform protects 500M+ users from spam, fraud, and deepfake scam calls, and gives businesses branded, verified caller ID so the calls that matter get answered.
We're hiring a senior backend engineer for a small foundational team building our next-generation voice products from scratch: real-time SIP/RTP media handling, STT/TTS pipelines with tight latency budgets, deepfake detection and speaker verification, and conversational AI, all integrated directly into carrier networks. It's greenfield, so you'll be making the early architecture decisions, not maintaining legacy services.
Stack: TypeScript/Node.js, Python, Kafka, Docker/Kubernetes on AWS. Telephony experience (SIP, RTP, WebRTC) is a plus, not required. Team is distributed across Seattle and Europe, async-first; 3 days/week in the Seattle office.
InfoHawk | Software Engineer | London, UK or NYC | REMOTE (UK or US), occasional onsite | Full-time | https://www.infohawk.com
Fraud reaches people through ads, cloned brand sites, counterfeit shops and AI-generated video, and it moves faster than any manual review. InfoHawk detects it while it is still running, correlates it across platforms and formats, and surfaces it early enough for our customers to act. We are a small team of engineers plus security, privacy and fraud specialists. Pre-seed, $2.25M led by Moonshots Capital: https://www.infohawk.com/news/2026-06-08-pre-seed-funding-an...
You’d own how data gets in: scrapers and collectors that survive source changes, official APIs where they exist, undocumented endpoints where they don’t. Sources break constantly. Can you figure out how to use AI to spot the change and adapt automatically? Stack: TypeScript, Node, SvelteKit, Postgres, Playwright, heavy AI-assisted development.
We’re looking for ~3-5 years building scraping or integration systems in production, but if you’re a great engineer who doesn’t tick every box we’d still like to hear from you. UK-based for London, US-based for NYC; we cannot sponsor visas. Two of our three founders are engineers, one in each city, and you’ll work with them directly.
We're the system of record for the Canadian vehicle: raw automotive data turned into facts that can be checked. Our open-source VIN decoder sits underneath a government vehicle registry.
Some of what's interesting:
- A government registry, a manufacturer's own filing, a listing site and an insurance record will describe the same truck four different ways, and nothing in any of those files says they're the same truck. Reconciling that, for every vehicle in the country, in a way that holds up when a regulator asks how you know, is most of the data work.
- Seventeen characters on a door frame encode manufacturer, plant, model year and build attributes — badly, inconsistently, and differently per manufacturer. Public reference data covers some of it. The rest gets worked out from filings, recall documents, and patterns inferred across millions of vehicles.
- We read vehicles directly over OBD-II now. Forty modules answered on a recent Hyundai, each reporting its own part number and installed software version. Nothing downstream of the VIN moves when a module is reflashed, so no registration, history report or dealer system knows what software is actually in a car.
Pagelove collapses the modern web stack into its simplest form: no databases, no APIs, no application servers. Just HTML that works like an app, scales like a CDN, and is AI-native by design.
The page becomes the application, API and persisted state. Humans and machines can read and update the same surface directly using CSS selectors over HTTP, rather than through separate HTML and API/MCP interfaces. With Pagelove, AI can finally build web applications without having to deal with the complexity of the full stack.
We’re seed-stage and well-funded, hiring our first non-founder engineer. The codebase is Rust, with work including distributed storage, HTTP caching/ETags, CRDTs, parser/DOM performance, CI and production infrastructure.
Our development process is heavily agentic: Claude Code and Codex do substantial implementation work, with humans focused on architecture, review and the hard problems.
Noricum | Senior Backend Engineer, Payments, Ledger & Provable Fairness | REMOTE (2h overlap with US Pacific) | Contract to permanent | $120-160/hr | Start by 14 Sep
I'm the founder of Noricum where we build platforms – currently the money infrastructure, ledger, engine and payment rails behind a pre-launch wagering platform with a Steam skins economy. The games, a cashier and a bet ledger are built and live as a front end, with written specs for the server contract: ledger schema, refusal table, round lifecycle, every game's arithmetic. Processing and licensing are secured. The server does not exist. That is the job. You would own:
- A server-authoritative game engine - seeds, nonces, outcome computation
- A double-entry ledger where balance is derived and no client write can change it
- Server-side enforcement of every limit and refusal
- Payment rails idempotent under duplicated webhooks
- Seed custody and the provably-fair lifecycle
- An affiliate system with referral attribution and commission payouts
Must have shipped: a double-entry ledger or equivalent money system in production, a payment integration including webhook idempotency, auth and sessions you built and operated, and infrastructure you owned end to end. Provably-fair systems, settlement-side gaming or trading infra, or Steam trade automation all stand out.
Email michael@noricum.io with your start date and a few lines on the last money system you shipped - what it guaranteed, and how you knew it held.
Our mission: make handling memory, state, and context for AI agents outside the cloud as simple as it is in the cloud. Today it isn't close. An agent without data is inert, and outside the cloud, data is duct tape.
An agent in the field needs data that is verifiable, auditable, concurrent, collaborative, and permissioned. No single system gives you all five. SQLite gives you local storage and nothing else. Every other database assumes the cloud is there to provide the rest.
We're building the data layer agents actually run on: local-first, syncs peer to peer, every write verifiable, every read auditable, no cloud required. The stack is open source: https://github.com/sourcenetwork/defradb. We think it's the best memory an agent can have, bar none.
We’re growing fast and are looking to fill the following positions:
Vitalize | Senior Product Manager or Staff Product Manager | San Francisco (hybrid)
What we do:
Hospitals run critical operations (staffing, labor planning, and capacity) on spreadsheets, phone calls, and gut instinct. Labor is the biggest cost and hardest operational problem, and it’s still largely manual. Vitalize is building the operating system for hospital labor (and ultimately capacity): we forecast demand from real hospital data (e.g., ADT + historical patterns + acuity) and translate that into concrete staffing decisions: next month’s schedule and the next shift.
Traction:
- ~$37M raised
- Launched 2024; ~$13M committed ARR across 10+ health systems
- Live in 20+ hospitals and growing quickly
The role:
We're hiring a PM to own the product experience that takes a hospital from signed contract to successfully using Vitalize in production. Getting there is complex: every health system has its own HRIS, scheduling workflows, union rules, and technical environment. This team builds the custom integrations and internal tooling that make those deployments faster, more repeatable, and less manual as we scale.
We're looking for a PM who...
- Led messy third-party enterprise integrations deep enough to make real technical calls with eng
- Has built internal tooling with an internal team as the customer
- Prioritized a roadmap under live GTM pressure and held the line when the loudest deal wasn't the right build
- Startup experience, where the system you were building didn't exist yet

Brilliant is building the world's first graphical AI tutor: a collection of interactive learning experiences that both the learner and their AI tutor can see and manipulate. In a world of cognitive offloading, Brilliant's AI gets people to actually think and solve hard problems.
We're hiring an interactive-focused engineer to craft the building blocks that power it. Each interactive exposes an API used by learning designers, our authoring agents, and the tutor itself. And every configuration those APIs can produce has to be a correct, solvable, meaningful puzzle. It's a tricky technical problem with a big payoff for our learners.
Engineers at Brilliant think about both "building the right thing" AND "building the thing right" while pursuing high standards of excellence for ourselves, our product, and our codebase.
If you're energized by the prospect of doing the best work of your career and changing how the world learns, you can learn more and apply here: https://brilliant.org/careers.

Mondrio | Founding Product Engineer | San Francisco | ONSITE | $200k – $250k plus equity
Mondrio (https://mondrio.io) builds agentic pricing management: AI agents plus pricing experts that keep B2B pricing current rather than a one-off, one-time exercise. The founding team ran 150+ pricing engagements before starting the company and are translating that expertise to shape the next frontier of pricing in the agentic era.
The role comes with significant scope and high autonomy. You will own the full product lifecycle: customer discovery -> rapid prototyping -> agent-ready specs -> shipping via agentic orchestration -> o11y and evals -> growth & expansion.
Here are some domains you will ship:
- Multi-agent simulation to emulate the behavior of a buying committee
- A2A pricing interactions governed by OPA/Rego policies defined from natural language
- Generative UX driven by a MCP server with full system capabilities access
- Autonomous quote generation and real-time deal intelligence during sales calls
We don't have PMs or product designers so you serve as the product bridge between the founders, pricing experts, and engineering. If you're a mature engineer, looking to work with a very senior/staff team across the stack: customers, models, server, clients (web, TUI, chatbots), evals, then this is the role for you. In short, the role is ideal for someone who has significant product engineering expertise and has sharpened their SDLC competency to be AI-native.
Everyone in health AI is chasing scribes and diagnostics. Almost no one is building the longitudinal data layer that captures what actually happens to patients over time. That is the real moat, and we are building it for eye care.
Deya sits between doctor and patient, capturing symptoms, treatments, outcomes and ocular images over time. Clinician-led, piloting with eye doctors, and we hold the largest dataset of eye images captured on smartphones. We build with AI tools daily.
Three roles, all high ownership:
Software Engineer (AI x Healthcare)
- Product and infra from 0 to 1. Next.js, backend, cloud, agentic workflows, longitudinal clinical data.
Mobile Engineer (React Native, Swift, Kotlin)
- A modern phone is already a clinical instrument and almost none of it has been pointed at eye care. Own the app and its UX end to end.
AI Engineer (Computer Vision + LLMs)
- Own the vision pipeline turning phone photos into clinical signal, plus the LLM systems reasoning over patient history.
We have a proprietary clinical dataset and because we control capture, you can improve the data itself rather than model around its limits. Optometrists and ophthalmologists in-house to define ground truth and validate the work. Competitive salary plus equity.
Odyssey is building the leading financial technology platform for school choice. We help families access funding for tuition, tutors, curriculum, software, and enrichment programs—empowering them with greater educational opportunities.
We’re well-funded, backed by top investors including Andreessen Horowitz (a16z), and we are rapidly scaling.
As Odyssey's first Security Engineer, you'll have full ownership of our security posture — shaping strategy, building programs from the ground up, and driving best practices across our entire technology stack and product suite. This is a high-impact, high-visibility role where your decisions will directly influence how we protect our customers, vendors, and employees.
You'll partner closely with cross-functional teams to embed security into everything we build and ship, champion solutions to emerging security challenges, and ensure we stay ahead of an evolving threat landscape. You're someone who embraces AI tools to work smarter — whether that's accelerating threat detection, streamlining vulnerability analysis, or improving how we respond to incidents.
Newtwen is building a cloud platform that brings complex physics and data-driven intelligence directly onto microcontrollers, generating ultra-fast runtime firmware that executes in just a few microseconds.
We're looking for a Senior Backend & Cloud Platform Engineer to help architect and build our first production-grade cloud backend from the ground up. You'll own backend services and computational pipelines spanning 3D geometry processing, mesh generation, model order reduction, calibration and neural network training.
A core part of the platform is dedicated to data-driven modeling, with a specialized neural-model library designed to make physical models adaptive in real time.
You might be a good fit if you have: strong production backend/cloud experience, Python (FastAPI or similar), relational databases, Docker, cloud infrastructure (GCP preferred), CI/CD and IaC — and enjoy making architecture decisions rather than just implementing tickets.
Location: REMOTE (EU), with the option to work hybrid in Italy
Compensation: €70k–€90k+, depending on experience
Apply: career@newtwen.com — mention Hacker News and include your LinkedIn/CV and, if available, GitHub or project links.
Factory | Security Engineer | Onsite in San Francisco | Full-time
Come work on my team! (We’re hiring lots of engineers right now, but I’m biased toward my own group today.)
Factory builds software development agents that accelerate the world's largest enterprise engineering teams. We're helping customers including Nvidia, Adobe, Adyen, Klarna, and Ernst & Young turn their engineering organizations into autonomous development systems — shipping code, reviewing PRs, running tests, and deploying continuously.
We're seeking a talented Security Engineer to join our team. In this role, you will play a critical role in developing and maintaining the security foundation of our platform. You will conduct in-depth code reviews, implement security best practices, and influence the overall security strategy. Your expertise in TypeScript, Python, Kubernetes, CI/CD, and terraform orchestration will be crucial in identifying and mitigating potential security vulnerabilities.
ODK is an open-source platform used by thousands of organizations worldwide to collect billions of data points for disease surveillance, supply chain traceability, environmental monitoring, and more. It enables users to build powerful forms and reliably collect structured data, even in places with little or no Internet connectivity.
ODK has been actively developed for 18 years. We have a mix of self-hosted and SaaS users across many sectors. We're looking for a senior product manager who will own product discovery and prioritization across this diverse user base. To be successful, you'll need to find the common needs behind very different workflows and turn them into opinionated product improvements.
Because the team is small and the user base is large, this is a high-autonomy role where product decisions have an unusually direct impact. You should have substantial experience managing complex B2B or technical products. Experience with open source, self-hosted software, and small, fully remote teams is a plus.
We're a VC-funded startup (recently raised $51M Series C) building an infrastructure orchestrator and collaborative management platform for Infrastructure-as-Code – from OpenTofu, Terraform, Terragrunt, CloudFormation, Pulumi, Kubernetes, to Ansible.
On the backend we're using 100% Go with AWS primitives. We're looking for backend developers who like doing DevOps'y stuff sometimes (because in a way it's the spirit of our company), or have experience with the cloud native ecosystem. Ideally you'd have experience working with an IaC tool, i.e. Terraform, Pulumi, Ansible, CloudFormation, Kubernetes, or SaltStack.
Overall we have a deeply technical product, trying to build something customers love to use, and have a lot of happy and satisfied customers. We promise interesting work, the ability to open source parts of the project which don't give us a business advantage, as well as healthy working hours.
We build the first AI-native ERP OS. Competitors measure customer migrations in quarters, we offer Day-One data migration.
Backed by Google, Lightspeed and Khosla with a 90M series A, we're building a team of outliers. The people who raise the bar. The builders. The ones who move fast and consistently do exceptional work.
It's high ownership, greenfield work and many of our roles are first hires. You'll grow along with the product and the team.

Virtasant (1099 contractor for a client of ours) | Virtasant.com | Remote (USA)| full-time
Hey, we are a finops/cloud optimization company that also helps some of our clients with their hiring needs. For one of them (a solid healthcare data company) we're looking for a Senior Data Engineer.
The legal stuff:
You need to live in the USA and be under one of the following conditions:
a) US citizen
b) Green Card holder
c) Sole owner of your own LLC company (not co-owner, sole owner)
Sadly, all other options are not possible, like H1B, OPT, EAD, or CPT visas, are not possible for us.
80-90 USD per hour, changes of going a bit above if the candidate is amazing.
The tech stuff:
7 yoe (5 of which building production-grade data or platform services), AWS-heavy (if you're stronger on Azure or GCP, then it's not for you, sorry), Python, SQL, dbt, (Snowflake OR BigQuery OR Redshift), Spark, Kafka, (Iceberg OR Delta OR Hudi), (Airflow OR Dagster OR Prefect), CI/CD, Docker, AWS.
Duets Network is an AI-powered platform connecting startups and investors across the sports and entertainment industries. We are building a dynamic ecosystem that bridges founders, capital, and strategic partners to drive meaningful growth and collaboration at the intersection of technology and culture.
The initial product is built out, and we're now looking for a fractional Founding Engineer to guide the technical side moving forward: architecture, infrastructure, data/recommendation systems, security, and scalability.
Our founding team: CEO, ex-Universal Music Group; CBO, ex-Andreessen Horowitz. You'd work directly with the founders, with no existing engineering org, and would:
- Assess and improve the existing React / Node.js / PostgreSQL / AWS codebase and infrastructure
- Set engineering architecture, standards, and technical priorities
- Design the data + recommendation/scoring layer behind founder/investor/partner matching
- Build out DevOps, CI/CD, monitoring, and deployment processes
- Make pragmatic build-vs-buy decisions and coordinate external engineers/vendors as needed

Balerion AI | Software + FDE + AI Engineers | San Francisco, CA | ONSITE | Full-time | $250k+ base + seed equity | Visa sponsorship available | https://balerion.ai
We're building agentic AI for mortgage lending — automating document processing and income qualification for loan originators.
Underwriting a loan means pulling numbers out of a few hundred pages of paystubs, W-2s, bank statements, and tax returns, then applying underwriting guidelines that run to thousands of pages of edge cases. Most of it is still done by hand.
Problems we actually work on: routing scanned pages to OCR vs. text extraction when the text layer is unreliable; extraction pipelines where a wrong number is much worse than a missing one; running long agent workflows durably so a failure three steps in doesn't restart the whole loan; and evaluating multi-step output against guidelines that are themselves ambiguous. We put real effort into eval infrastructure, because "the demo looked good" does not survive contact with a lender's compliance team.
Stack: Python, PydanticAI, Restate for durable execution, Postgres, AWS. Frontier models from OpenAI and Anthropic plus open-source models where they win on cost or latency.
We raised an $8M seed led by Kleiner Perkins and have paying customers in production. Team previously at Snowflake, PayPal, Twitter, Atlassian, and Microsoft.
Comp: $250k+ base, meaningful seed-stage equity, 5% 401(k) match, full health coverage, commuter stipend, gym membership, daily office breakfast & lunch. Full relocation to SF covered.
Onsite in SF. Visa sponsorship: yes.
Email vishal@balerion.ai with "HN" in the subject, plus a resume or GitHub.

Ownership. You should own a piece of what you build here. We are not going to post a percentage, because the honest answer depends on what you end up carrying, and we would rather work that out with you than hand you a number that pretends to be precise. It is a conversation, it is flexible, and we intend it to be fair.
We are six people. Nothing you build goes through a committee before it ships. Nothing you break, you fix alone. We are a tight team today and we are looking to double it by the end of the year.
Please send your resume or GitHub, plus the most ambitious thing you have built mostly on your own. Rough work that worked beats polished that never shipped.
If this is not you but a name comes to mind, please pass it along. :)

AI data centers are creating a massive new wave of electricity demand and putting even more strain on an aging grid. Strobe is building the power company that will meet that demand.
Our software turns batteries and generators at commercial and industrial buildings into distributed power plants that can buy, sell, and dispatch electricity in real time. We build the control stack for operating these assets and the trading platform that connects them to wholesale energy markets.
We’re a small, high-ownership team working on critical infrastructure. You’ll learn how the energy system actually works: what happens inside the electrical room of a large commercial building, how data centers are powered, how utilities and grid operators communicate, and how a battery gets commissioned and brought online.
This is early, technical, and very real-world. The software you build will control physical equipment, keep power plants online, and move money in regulated markets. We’re the only company actively trading distributed power in FERC-regulated wholesale markets, with multiple behind-the-meter power plants operating in NYC and expansion underway in California and along the East Coast.
I’m looking for an experienced SRE to own our infrastructure and reliability. We remotely operate millions of dollars of equipment, and it has to work. You’ll own our AWS environment, the control-room infrastructure that communicates directly with utilities and market operators, and the systems we use to deploy, observe, and operate a growing fleet. You’ll also work closely with the rest of the engineering team to establish good patterns as we ship new services and features.
You’re probably a good fit if you have deep AWS experience, have used Terraform seriously in production, write a lot of Python, and are comfortable working around Rust services. Energy experience is useful but not required (SCADA, DNP3, MQTT).
Stack: Python, TypeScript, Rust, Terraform, AWS, GraphQL/AppSync, MQTT, Grafana. We work in a monorepo designed for agent-assisted engineering workflows and are investing heavily in making engineers dramatically more effective with coding agents.

I’m hiring two engineers for Attentive’s List Growth team: one Senior and one Staff. We build the signup experiences that collect email addresses and phone numbers for brands using Attentive. It’s a high-scale, top-of-funnel product used across billions of site visits.
Both roles are full-stack but backend leaning. Our backend is primarily Java/Kotlin and Spring Boot on AWS and Kubernetes; the frontend is React and TypeScript. The work includes distributed systems, APIs, experimentation infrastructure, and customer-facing product development.
The whole team is based in NYC and works together in the office Tuesday through Thursday. The Senior range is $170k–$230k; Staff is $205k–$275k, plus equity and benefits.
Whoever posts this monthly, please include the tag in your description. Employers need to know this is an in-demand feature we want. I for one will not be taking any non-4DWW jobs.
cloro is one API for search and AI answers. You send a query, we return Google, Google News, ChatGPT, Perplexity, Gemini, Grok and Copilot results as structured fields: the answer, the sources it cited, and the position each result held. Teams use it to measure whether their brand shows up in AI answers, and to stop maintaining eight scrapers that break whenever a provider changes its markup overnight.
We are bootstrapped, remote across EU timezones, and small enough that every role below works directly with the founders.
* Founding Operations | $50k-80k | finance, ops, marketing and product systems. An all-rounder role for someone who would rather build a system than run a task twice. https://cloro.dev/careers/founding-operations/
We work AI-native: Claude and Claude Code are in the loop daily across
engineering, ops and marketing. Being genuinely good with these tools is
part of the job rather than a bonus.
Starbridge | Senior AI Engineer and Senior Product Engineer | NYC or Remote | Full-time |
https://starbridge.ai/
Starbridge is building an AI platform that turns large-scale public and enterprise data into reliable sales insights. We are early, moving fast, and building from zero to one, so this role will have huge ownership and product impact.
AI Engineer: Applied AI plus strong software engineering. You will build, evaluate, and deploy LLM-driven features like deep document analysis and interactive chat, working with models from OpenAI, Anthropic, and Gemini. Expect hands-on Python, ML system design, experimentation, and production reliability. Bonus for RAG depth and frameworks like LangChain, LlamaIndex, or Hugging Face.
Product Engineer: (React/Typescript) who would work closely with product and design to build user-facing parts of the platform. You will craft performant, stable frontends that explain technical concepts to non-technical users and help us iterate fast based on customer feedback.
We're looking to build our in-person team in NYC but also open to remote!

Justworks | HYBRID (2-3 days a week) | NYC, Toronto
Justworks helps small businesses manage payroll, benefits, HR, and compliance so they can focus on running their business. Looking to fill lots of tech roles across all levels!
Shovels is the intelligence layer for the built world. We're venture-backed, trusted by some of the largest Fortune 100 companies in the world.
We have a lot of customers and a lot of technical needs from those customers. That's why we're hiring a true Forward Deployed Engineer: a real engineer who wants to work shoulder-to-shoulder with customers and turn their hardest questions into working solutions.
You'll embed into our most important enterprise accounts, understand what they're actually trying to do, and build the maps, models, and data products that make Shovels indispensable to them, working alongside AI agents the way the rest of our engineering team does.
This is not a hand-off role: you own the relationship and the build, from the first "what if we could see…" to the moment the customer says "wow."
Modash helps brands find, manage, and pay creators - and helps creators earn a living.
The product looks simple on the surface. Underneath, we index 380M+ public creator profiles across Instagram, TikTok, and YouTube so that 1,700+ brands search, evaluate, manage, and pay creators without drowning in spreadsheets and tabs.
We're looking for Senior Product Engineers who like owning ambiguous problems end-to-end. No perfectly shaped tickets. You talk to customers, understand messy workflows, make product decisions, ship, and own whether it actually works.
The problems we care about:
- How do you make a 380M-profile dataset feel fast, trustworthy, and easy to explore?
- How do you turn chaotic influencer marketing workflows into product that feels obvious?
- How do you build tools that work for both small teams and brands like Stanley, Sennheiser, Birkenstock, and NordVPN??
We're 85 people, raised an €11M Series A, and ARR is doubling every year. HQ is in Tallinn, engineering is fully remote across Europe.
No ticket factory. No seven layers of approval. Small teams, real ownership, hard product problems.

* Flexibility and a low-bureaucracy environment
* Clients that won’t treat the vendor like “the B Team”
* The chance to act as a code architect, not just implement tickets
* Exposure to a wide variety of industries and modern challenges
* Me as your personal champion and advocate

8 years ago, Jeremy was absolutely frustrated with the status quo of data infrastructure in manufacturing. Companies paid millions per year for "shitty 90s software" and are still doing that today, when there is much better software out there for open-source. So we decided that we can do this better, first founded a System Integrator, realized most of the tasks in setting up and maintaining a data infrastructure can be standardized, and decided to found the currently VC-backed UMH, which is built on open source software and is open source itself.
What we're actually building: We build and scale a real-time data platform that runs hundreds of Benthos pipelines inside a single Docker container (UMH Core), processing millions of industrial messages that control actual production processes.
Plus a local-first user interface (Management Console) where both non-technical factory workers and power-users/developers can work together. And yes, we care about UI in enterprise/industrial software.

- Langs: TS / Python - Infra: Nix, CDKTF, AWS
We’re hiring from infra to full stack. Come share your proudest firefighting story with us in an interview, bring your GitHub, and let’s see if we’re a good fit!
I'm hiring for a frontline EM building the automation and trust layer for freight pricing, matching, onboarding, and settlement.Lead 1-3 teams (FTE + contractors), own delivery end-to-end, ~8 yrs exp typical. I expect everyone in my eng org (myself included!) to be technical and be able to help unblock the team, though your day-to-day wont be in the code.
Technical here means you can/will get into the code yourself and architecture reviews and maintain technical credibility with our junior to staff/principal level engineers. These are not player-coach roles, but these are frontline roles that need that technical capability.
Interesting problems: trust/fraud at marketplace scale; legacy-data-meets-modern-stack; and all kinds of problems that come with powering hundreds of thousands of load/shipment postings every day.
AI/LLM: We are leaned in, but still hold humans responsible for what they push and expect everyone to review and understand llm output before asking other humans to look at a thing.
Culture: I am deeply familiar with Google's project oxygen/aristotle and am building a culture where our teams can do great work with minimal bs.
Location: Must be local to one of our three locations (Seattle, Portland, Denver).
Paramark | Software Engineer (L4) | San Francisco HYBRID (3 days/wk) or REMOTE (US) | Full-time | $199K–$249K + equity
Paramark helps Marketing teams optimize spend across all of their channels and programs. There are proven scientific ways to do this, but they are poorly understood and practiced by only a tiny fraction of teams. Our product ingests data from all of our customers' marketing channels and uses it to train open-source ML models for both measurement and experimentation. This makes it possible for any marketer to use these methods.
In this domain, it's hard to figure out what to build, and it's even harder to be both accurate and simple. You'll be joining a small team -- we have four product engineers. That means owning systems end to end and having real influence over what gets built. Your typical project will start with a high level goal, and you will figure out the rest.

Foray Bioscience | Software Engineer, Data & ML | On-Site (Cambridge, MA) | Full Time | $105,000–$130,000 + equity
Company:
Foray is a plant production company using plant cells, artificial intelligence, and advanced biomanufacturing to grow materials, molecules, and seeds directly from the cell up.
Our work is powered by Pando, our intelligent workspace for plant science. Pando combines novel plant datasets and emerging predictive models to help researchers design and optimize plant production workflows with greater speed and reliability. Together, our software and biomanufacturing platforms are creating new ways to produce what we need from plants while building more resilient plant industries.
Role:
We’re looking for a Software Engineer, Data & ML to help build the software and data foundation behind Pando. You’ll work across the product, with a particular focus on backend systems, APIs, data infrastructure, and the systems supporting our machine learning work. A major part of the role is figuring out how to turn complex scientific and experimental information — including scientific literature, natural language, and data generated in the lab — into reliable, structured data.
You’ll work closely with software engineers, biologists, and ML researchers to translate experimental workflows, statistical analyses, and design-of-experiment approaches into scalable software and predictive tools. You’ll join early, have significant ownership, and help make foundational technical and architectural decisions as the platform grows.
You:
+ Strong software engineering generalist with particular depth in backend and data systems
+ Experience shipping production-grade software and building backend systems, data pipelines, databases, APIs, or other data-intensive infrastructure
+ Strong in Python and comfortable with relational databases, APIs, and modern software systems
+ Familiar with MLOps and the infrastructure needed to run AI models in production
+ Comfortable turning messy, heterogeneous, or unstructured information into trustworthy data, including through NLP, information extraction, or similar techniques
+ Understand good scientific data practices including quality, provenance, versioning, reproducibility, permissions, and access controls
+ Enough statistical fluency to reason about experimental data, uncertainty, and design of experiments
+ Enjoy learning unfamiliar domains, working across disciplines, and solving ambiguous problems with significant ownership
+ Experience with scientific or biological data, ML infrastructure, predictive modeling, optimization, or AI applications is helpful, but we don’t expect one person to have done all of these things before
+ Must be authorized to work in the United States
Prior Labs | Berlin, Freiburg, NYC | ONSITE | Full-time | ML Infra, Research Scientist/Engineer, Backend, Full Stack
We build foundation models for tabular data. Deep learning transformed text and images but mostly skipped tables, which are still the data behind most clinical trials, financial models and scientific experiments. The reason is structural: no natural sequence, no spatial structure, no shared vocabulary across datasets, so the architectures and scaling laws behind LLMs don't transfer.
Our approach: pre-train a transformer on millions of synthetic datasets sampled from causal-structure priors. The whole dataset goes in as context, predictions come out in one forward pass. No per-dataset training, no hyperparameter tuning, seconds instead of hours. TabPFN v2 was published in Nature and set a new state of the art; TabPFN-3 scales to 10M rows. 4M+ downloads, 8k+ GitHub stars, in production from liquid biopsy to rail maintenance. Code: https://github.com/PriorLabs/TabPFN
Since July we're an independent lab inside SAP, with more than EUR 1B committed over four years. Models stay open, research stays public, same team and offices.
Roles (most can sit in any of the three offices):
- Senior ML Infrastructure Engineer: own multi-cluster GPU infra (Slurm on GCP today, multi-provider next), training performance and the tooling layer. We spend tens of millions per year on compute; you own that budget.
- Research Scientist, Foundation Model: drive the model agenda - novel architectures, scaling from 10K to 1M+ samples, multimodal and causal directions. PhD plus top-venue publications, or equivalent.
- Research Engineer, Foundation Model: same agenda from the engineering side. You design experiments, write the training and eval infra, and co-author the papers.
- ML Engineer, Cloud Platform: design and scale the backend that serves and finetunes the models. Python/FastAPI, Terraform, K8s.
- Full Stack Engineer, ML Platform: build the product end to end. TypeScript + Python, React/FastAPI/Postgres.
Also hiring: Applied Scientist, Forward Deployed ML Engineer, Research Scientist (Foundational Data Science), PhD research interns, plus GTM and ops roles.
~40 people with backgrounds from Google, DeepMind, Jane Street, Goldman, G-Research, CERN. Led by Frank Hutter, advised by Bernhard Schölkopf and Yann LeCun. Comp competitive with top AI labs.
Mattermost | Remote (US and Canada) | FT | Multiple roles
Mattermost (https://mattermost.com) is an open-core collaboration and workflow automation platform for air-gapped, on-prem and private clouds. Our customers are in defense, intelligence, security and critical infrastructure, including the USAF and NASA. Y Combinator led our Series B, their largest open source investment at the time.
Both openings are full stack on the core platform: Go backend, React/TypeScript frontend, PostgreSQL and Redis. The codebase is public (https://github.com/mattermost/mattermost), so most of what you build is too. We would rather hire people who ship and own complex software end to end than chase an exact stack match, so any systems or backend language and any frontend stack counts. What we look for in both roles: REST and WebSocket APIs with real networking fundamentals (HTTP, connection lifecycle), and relational databases including schema design and query optimization.
We use coding agents daily (Claude Code, Cursor, and others) for scaffolding, refactors, code review and test generation, and we treat that as core craft rather than a shortcut around the fundamentals. If you have a track record of shipping and owning complex software end-to-end, we want to hear from you.
*Senior Full Stack Engineer* $142,723 - $172,723 USD
Architect and ship full stack features end to end, own the testing strategy for what you ship, and build internal tooling and testing infrastructure that makes the rest of the team faster. You will work without close supervision and hold the security and compliance bar our customers require. Nice to have: distributed systems and high availability architecture, regulated-environment security, open-source contributions, experience on remote-first teams.
*Staff Full Stack Engineer* $172,724 - $227,135 USD
Set technical direction for the platform rather than for a feature area: architecture and roadmap across the stack, the standards for how the org uses coding agents, and the strategy for internal tooling and testing. You will influence direction across teams, partner with security and compliance on it, and mentor senior engineers. Nice to have: staff, principal or tech lead experience elsewhere, open-source maintainership, FedRAMP or ITAR familiarity, defense or critical infrastructure background.
As a Senior Security Engineer (Product Security), you will play a significant role in keeping our product safe and secure by building on and maturing Zepto's product security practices. You will work hands-on and shoulder-to-shoulder with Engineering and Product teams, providing guidance and coaching across the software development life cycle while continuing to raise the bar on our security expectations and capability.
This is a security role at its core, but not a gatekeeping one. We are builders – we expect you to read and write production-level code, build tooling and automation, and contribute paved-road solutions that engineers actually want to use.
Reporting to the Security Engineering Lead, you will work closely with them to develop and build Zepto's product security strategy and approach. You will apply a consultative and advisory approach when working with the wider Zepto team, empowering them to work confidently and to use the self-service capabilities you help establish.
We have excellent working relationships with our developers and we need to keep it that way. We are not the team of no. We are the team that helps make things better.
Zepto is moving quickly towards an AI-native way of building and operating. You will be someone who is already experimenting with AI and agentic tooling, or is genuinely keen to, and who is open to developing the skills to secure these systems as we adopt them.
Within the Security team, you are the go-to person for:
Secure development practices

Stpkr Technologies is hiring for the following roles to build the next generation of wearable devices.
We are currently looking for the following roles but we are also open to interviewing any candidates who feel like they will do their best work here - even if your skillset/experience doesn't fit the current defined roles. Our current team doesn't fit the conventional mold, and we don't expect our future hires will either. If you don't fit the advertised roles, just send us a mail per the same process with whatever job title would fit you the best.
Work is in person near Noida Sector 18, walking distance from Sector 18 Metro Station. We prefer in office work, and for you to be located within Delhi/NCR, Pay is competitive (9-12 LPA), and there are opportunities to earn meaningful equity down the line. We prefer current and recent undergraduates for our roles. If you are still in college we welcome you to apply nonetheless provided you can work as an intern for us in person. Super-flexible overall and all of our current team started out as interns. We are not flexible on in-office work because of operational requirements - please do not apply if you can't relocate/work from office.
Hiring across OS, software, and hardware. AI policy across all roles: you should be able to do the work without AI, and much faster with it.
Systems Engineer - Everything at the OS layer. You've rooted phones, flashed custom ROMs, broken and fixed Linux for fun. Comfortable in C/C++. GitHub with kernel-adjacent or LineageOS-type projects a plus. Stack: Android, Linux, C, C++, Java. Filter: send us something you built where you had to fight the OS or hardware.
Hardware Engineer - Bring-up/Debug/Integration - Take EVT/DVT boards and make them work. Comfortable with J-Link and IDE debugging, reading schematics and reference designs. KiCad/Altium/EasyEDA hobby work would make you ideal. PetaLinux experience or hunger to learn it. ECE undergrad fine. Filter: photo of a board you designed or debugged, plus what went wrong.
Hardware Engineer - Power/RF/Wireless - Make the power and RF paths behave on EVT/DVT boards. Hands-on with schematic capture, layout, soldering, scope/logic analyzer. Given two unknowns, you pick one and start measuring. Filter: sensor fusion work, how noise behaves across protocols, and SPI debug chops.
Founder's Office - Work closely with the founder and the rest of the team to manage the day to day and long term affairs of the company, the Man Friday of the company. Must have a decent degree of technical knowledge (we are a tech company after all) and be efficient at administrative tasks as well as management. Speed and learning ability are prized here, there will not always be a clear path to the work you have to do here, so you will have to figure some of it out on your own.
To apply, contact arnav@stpkr.in with the subject line "HN - Human" and a brief intro for further communication. Attach any documents you deem useful there. Please include the role you are applying for at the top of the email if it is one of the above mentioned, otherwise whatever role fits you best. Shortlisting will be online, interviews will be in person. We are hiring quickly, expect to hear back from us within 2-3 days of applying. If you don't, assume you will not. If you are using an AI agent to mass apply for jobs and we can tell, then you will not hear back. Use an expensive one :P (reiterating this, because we receive so much AI spam now. Thanks for your time!
Aerdos | https://www.aerdos.com/ | SF | Full Time | $200-250K + equity
We're building an ai-native intelligence agency to help the USG answer the trickiest national security problems. We do this with lots of public/commercial data and ai.
Proxybase | Backend Systems Engineer (Rust) | Remote, Global | Full-Time
Hi HN,
I’m the founder of Proxybase [0]. We’re building a SOCKS5 proxy network focused on transparency and ethical sourcing in the residential proxy market.
A quick note for anyone who applied last month: thank you to everyone who reached out. We received far more strong applications than expected, and between running day-to-day operations and working through the backlog, we took much longer to reply than we should have.
If you applied last month and haven’t heard back yet, I’m sorry for the delay. We’re actively reviewing those applications alongside this new batch.
Why Proxybase?
The residential proxy industry has a rough history. Some providers rely on hidden background scrapers bundled into TV firmware or mobile apps, while others use payout systems that can hold provider funds for months.
We’re trying to build something better:
Open-source clients: Our GUI [1] and CLI [2] are fully open source, so anyone can inspect and audit what runs on their device.
Explicit consent: Providers knowingly opt in. No stealth bundling.
Fair, fast payouts: The minimum payout is $1, sent directly to provider wallets in USD stablecoins. We do not hold funds to earn interest on them.
We’re hiring a Backend Systems Engineer with Rust experience to help build:
Stack: Rust, Tokio, Axum, SOCKS5, Linux systemd daemons, SQLite
Location: Fully remote, async-friendly, flexible time zones
Compensation: Competitive salary plus equity. USD or stablecoin payment options are available.
If you’re interested in building infrastructure for an industry that needs better standards, email jobs@proxybase.xyz with your GitHub, résumé, and a short note about what you’ve been working on recently.
I’ll also be around in the comments to answer questions and hear feedback.
We're building the intelligence layer for physical risk: digital twins of individual homes, run through physics-informed AI World Models, to see exactly how a specific property will perform in a wildfire or hurricane — traditional models only guess at the neighborhood level. That precision lets us do what insurers historically couldn't: measure how much a new roof, cleared vegetation, or better siding actually cuts risk, then price coverage accordingly, turning mitigation into a real financial incentive instead of just advice.
We've scaled to ~$10B in insured assets in just two states in under a year. The interesting problems: ML surrogates that run physics simulations 1,000x+ faster without losing accuracy, structure-level digital twins built from imagery and property data at scale, and systems that reason across risk, cost, and homeowner tradeoffs — we're hiring across engineering and applied science.
Astoria AI | Founding AI Engineer — Agentic Systems | Remote (async) | Full-time | Equity-only pre-seed, $190k-$280k + equity post-seed
Astoria AI is building an agentic runtime for human potential — a suite of specialized AI agents serving candidates and companies across the entire hiring and talent lifecycle: career strategy, networking intelligence, verified matching, compliance-native hiring, onboarding, and retention.
The hiring market is structurally broken: 44% of resumes contain fabrications, ATS filters reject 88% of qualified candidates, and 27% of posted jobs are ghost jobs — while regulation (EU AI Act, Mobley v. Workday, FCRA suits) is forcing enterprises to rethink hiring AI. We're building the fix.
You'll own the intelligence layer: LLM-powered agentic workflows (tool use, structured outputs, multi-step orchestration), RAG/retrieval pipelines, lightweight ML for classification/ranking/entity matching, and evaluation loops for hallucination risk and output quality.
Looking for: 6+ years professional SW engineering (Python/TypeScript/APIs/DBs), hands-on experience with LLM APIs and agentic workflows, and ideally RAG/embeddings/vector DB experience beyond basic chatbots.
Stage: pre-launch, pre-seed, founding team, equity-only until seed round closes (~4-6 months), then competitive salary + refresh grants.
Apply: Konstantin.mueller@astoria.ai with „HN“ in subject, plus resume or GitHub
> Commenters: please don't reply to job posts to complain about something. It's off topic here.
But also: while I didn't post this, that's not uncommon for a founding engineer. They're looking for someone to help start the company from scratch, typically with a healthy dose of equity. It's a calculated risk for the engineer, possibly worth anywhere from zero to a gazillion dollars depending on outcome.
I normally wouldn't comment, but expecting someone with that skillset and those kind of opportunities available to them to work for free for 4-6 months with the promise of actual pay "when our seed round closes" was so egregious I couldn't help myself, sorry.
That's common for founders, though. The CEO and CTO etc. are almost certainly in the same boat. They're not so much saying "come work for free" as "come join this group of us who are taking a leap from our current jobs and building something brand new, in hopes it'll pay off wildly."
SerpApi | https://serpapi.com | Junior to Senior Fullstack Engineer multiple positions | Customer Success Engineer | Hiring Coordinator | Python/Ruby/PHP/Js/Rust/Cotlin/C#/Crystal/Nim/Elixir Developer Advocate positions | Based in Austin, TX but remote-first structure | Full-time | ONSITE or FULLY REMOTE | $150K - 180K a year 1099 for US or local avg + 20% for outside the US
SerpApi is the leading API to scrape and parse search engine results. We provide 100+ APIs to Google, Google Maps, Google Images, Bing, Baidu, and more.
Our current stack is Ruby, Rails, MongoDB, and React.JS. We are looking for more Junior and Senior FullStack Engineers.
We have an awesome work environment: We are a remote first company (before Covid!). We do continuous integration, continuous deployments, code reviews, code pairings, profit sharing, and most of communication is async via GitHub.
We value super strongly transparency, do open books, have a public roadmap, and contribute to the EFF.
Hi, I applied for the junior role two months ago. I never heard anything back, but I'm also somewhat concerned my email got lost entirely because I sent emails from two separate addresses - one got an immediate automated response, the other got nothing. (The second email that received a response was just a generic inquiry checking on the first, so I'm concerned that one got tossed by the automated system as well). I'd be grateful if you could let me know if it was ever seen!

New Lantern | https://newlantern.ai | Software engineers (backend and generalist product engineers, founding recruiter) | Full time in San Francisco, CA (ONSITE)
New Lantern is building an AI radiology resident—think Cursor for radiologists. Our application integrates the three software tools radiologists use all day [1], together with AI, to create a platform that saves radiologists toil and lets them focus on reading images and finding disease.
We are a series A startup with ~20 engineers (~40 total staff), have a number of live customers generating revenue, plenty of runway, and are backed by Benchmark, Anthropic, and other great investors. Our customers have told us they would cry if they couldn't use our product anymore.
We're hiring for backend and product engineering, as well as a founding recruiter to help us scale. You'll work directly with our founder/CEO, our staff radiologists, and our end users to build a product that radiologists rely on daily. You'll have real ownership and autonomy, and ship meaningful work frequently.
I'm Steve, New Lantern's Head of Engineering. If you're interested or want to learn more, shoot me a note at (my HN username)@newlantern.ai. I've already hired one engineer from HN this year and interviewed many more!
[1] a radiology image archive & viewer, a medical report dictation system, and work management system
We're ~160 people, fully remote, building an AI marketing platform. Our main product is OTTO, which runs a site's SEO on its own - it reads live search data and pushes the technical and on-page fixes itself, nobody queues them up. Around that we've got ad automation for Google and Meta, GBP management for multi-location brands, content gen, and LLM visibility tracking (whether ChatGPT and co are citing you). Autotrader, Hyundai, P&G, Vendasta are some of our customers.
Work happens in pods, 1 PM and 2-4 engineers. You own your pod's roadmap and ship it with them, no veteran PM signing off on your specs first. That's the part most PM roles won't hand you.
Looking for 3+ years PM in B2B SaaS with an actual technical background - eng or QA before PM, or a PM who's been getting into the codebase themselves. You should be able to read Python and TS, write your own SQL, find your way around an API, and not need an engineer to tell you what a stack trace says. We're Django on the back, React/Next on the front. QA is yours end to end including release sign-off, people tend to underestimate that bit. And you're already using Claude Code or similar daily, not "open to it".
Process is screen with me, a take-home that runs about 75 mins, technical round with one of our senior PMs, then a call with our Director of Product (who you'd report to). I usually come back to people within 2 business days.
Our ATS forces us to list specific countries but we hire from anywhere as long as you can do EST hours, so apply even if yours isn't on there.
Apply at the link and mention HN somewhere, in your pitch or wherever it fits. I'm João Pedro, I read all of them. joao.pedro@searchatlas.com if you need me, though the link's faster.

Wikimedia Foundation | Lead Product Manager, Security | REMOTE (US + 18 countries) | Full-time
I lead the security and safety team for Wikipedia, at the Wikimedia Foundation. I’m hiring a product manager to lead our security roadmap and steer the priorities of our security engineering team.
It’s a high-pace, shipping-heavy time for the whole project right now, as we are dedicating ourselves to surviving all the ways AI is messing with us and the internet, and getting to the other side of it. I joined myself about a year ago, and have found it to be a great time and place to swing big and surprise people.
This is a PM role and PM background is certainly helpful, but it’s not strictly required (everyone has the first PM job at some point). A technical background and security expertise are a must for this role, so we’re also open to people in engineering roles, who have demonstrated PM-relevant skills and are interested in making a pivot.
You can apply at https://job-boards.greenhouse.io/wikimedia/jobs/8140060?gh_s... - we don’t auto-filter based on AI or anything like that, I will personally see your resume.
Working for Wikimedia would make me actually consider moving back to the USA for the opportunity.(I'm in Japan for reference.) I previous contributed to Mediawiki and the extensions ecosystem for about a decade.
I‘ve been considering applying at WikiMedia for a while now, but [my country] is not in the listed countries. Is there a chance you‘ll expand this list in the future?
Ah, that is too bad. It's certainly always possible the countries list could expand in future, but it's not something I have insight into and unfortunately can't give you too much to go on.

MONUMENTAL | https://www.monumental.co/ | Amsterdam, The Netherlands | Full Time | Onsite
We make robots that autonomously construct buildings, starting with bricklaying.
There's a lot of vapourware in robotics, but we're deploying robots across multiple concurrent sites today - and generating revenue. In the last couple of months, our robots have built affordable social housing, health care living units, canal walls in the historic city centre of Amsterdam, and a youth sports centre. Help us to build things that matter in the long run.
We're looking for experienced software engineers for many roles. You can help us solve problems like:
- Data sync and analytics queries across a fleet of robots (that can be offline for hours at a time)
- Modelling buildings in code and finding the right UI for operators to edit them
- Designing systems for robots to drive safely and fully autonomously around a building site
Check out the progress we've already made on Atrium, our operating system for robotics: https://www.monumental.co/atrium
We're rapidly scaling up operations - we'll be building in the UK soon - and we need experienced engineers who can build the systems that manage all of that complexity. If you think that 'full-stack' could reasonably mean debugging firmware, mixing buckets of mortar _and_ writing React components, we are looking for you. Robotics experience not required!

What are the EU roles you specify here? career page is position specific and not broad like you seem to suggest
Yeah The Who's hiring format isn't a perfect fit for how we have it structured. In general, engineering can hire remote first if there's a good fit, and we have local entities or EOR processes for every EU country (to the best of my understanding)
Going through the engineering job posts but they seem to be all in the US. I'm the main maintainer of a popular OSS project using WebAssembly and want to stay in this area (OSS, C, WASM etc.). Looking at "Staff Engineer - Edge Protocols" because of the good overlap with my latest experience. Is this available in Europe as well?

Harmonic | Technical Trainer | REMOTE (USA, East Coast based) | Full-time | 85k-105k USD
Key requirements: Up to 50% time can be mandatory travel for on-site in-person training sessions, very variable across the year. But no requirement to work in the office. Corollary to that - fluent or very good spoken English level is required. (PS: in actual practice it's about 1-2 work weeks every 2 months or so, irregularly)
Harmonic is a telecom hardware vendor. We are making hardware for the DOCSIS cable, PON fiber and mixed deployments.
Technical Trainer specialist is responsible for the presenting to the customer (MSOs) technical specialists, field technicians etc. the full overview of all possible product offerings by Harmonic, the full technical overview of every possible deployment (depending on the client's requirements) and full configuration for all hardware involved, including 3rd-party hardware. So no debugging and accessing code is needed, but if anything is customer facing, it must be explained.
As a brief example:
- Configuration for the DOCSIS core; - Configuration for the PON core; - Video streaming config; - Network L2/L3 switching configuration for multiple vendors;
The other half of the responsibilities is creating training materials, both text and graphics (designer is assisting our team too). Recording live narrated sessions too.
A familiarity with networking and/or DOCSIS is required. Both would be great.

Hi! Are you also considering junior/early-career backend or systems engineers
I'm a recent Computer Engineering graduate interested in systems, distributed systems, databases, and infrastructure. I've been contributing to the PostgreSQL ecosystem (9 merged PRs) and have worked on distributed systems in Go, including Raft, a fault-tolerant sharded KV store, and a distributed file system. VictoriaMetrics looks particularly interesting to me because of the overlap with the kind of systems work I'd like to pursue. I'm based in Egypt, so EMEA remote opportunities would also be especially interesting.
Discord | Senior Software Engineer, Application Security | San Francisco, CA | ONSITE | $280K–$330K TC
Discord is where communities and friend groups spend time together, on desktop, mobile, and now more and more inside games and third-party apps built on our platform. That surface area, plus a huge, engaged, occasionally adversarial user base, makes application security a genuinely hard and interesting problem here.
We're hiring a Senior Application Security Engineer to join the Product Security team. Responsibilities include threat modeling and secure design review with product and platform teams, building and improving AppSec tooling (SAST/DAST/dependency scanning), and working directly with engineering teams to remediate findings.
Stack: Python primarily, some TypeScript/React, some Rust, occasional JavaScript. Runs on GCP.
Looking for: hands-on AppSec experience (not just compliance-flavored security), comfort reading and reviewing code across languages, and sound judgment on prioritizing real risk over checklist security.
Interview process: recruiter call, coding round, HM interview, virtual onsite, decision.
Apply: https://job-boards.greenhouse.io/discord/jobs/8656854002

Tufalabs | Zurich, ONSITE | Full-time | 100-200k CHF | https://tufalabs.ai/
(I want to preface that we don't have a ton of budget to expand our team right now and we want to keep the team small, but I also don't want to miss someone who would be a great fit)
We are a self-funded independent AI research lab in Zurich. Currently we explore ARC-AGI3, LLM/RL reasoning, and quant. We recently started a new LLM post-training and pre-training effort, led by some ex-engineers from the swissAI Apertus team. We also like to do some Kaggle on the side, our team includes the top #3 and #12 globally.
Our overall roadmap is to catch up with LLM capabilities, own the full stack, and use it to do our own independent research, pushing efficiency and looking for new paradigms. We expect our new cluster (2x NVL GB300) to be up by the end of the month.
Long term we want to switch to AI alignment/safety research as I believe this is all that matters when AI capability is high enough.
We look for people who are driven, who believe it's possible to make significant contributions to both AI capabilities and safety, and with previous experience pre-training and post-training LLMs and related infra.
If interested, email me at benjamin at tufalabs ai.

Renaissance Philanthropy | Research Engineer (Speech AI/ML) | Remote (worldwide)
Renaissance Philanthropy's aim is to activate a virtuous circle of increasing ambition and impact between philanthropists and innovators: by identifying frontier experts both in science and in new ways of solving problems; by tapping into the growing number of emerging philanthropists; and by building multi-sector initiatives that can harness the power of philanthropy, markets, and governments.
RenPhil's Engineering Hub supports mission-driven, grant-funded educational technology projects that seek to improve educational outcomes in fundamental skills like math and reading. This summer we're launching a program called LEVI Literacy, which has a goal of halving the number of struggling readers in the US within 5 years.
We're looking for an expert in modern voice AI to support this work. Our partner teams are building tools that assess and support early reading directly from children's speech in real classrooms — oral reading, spoken vocabulary tasks, whole-class instruction. These are hard, meaningful speech problems: young children's voices, noisy multi-speaker environments, and high stakes for getting it right — and fair — for every student.
We're looking for folks who:
- have built and operated production ASR or speech-processing systems
- know the full data-to-model pipeline: collection, annotation, fine-tuning, evaluation, and deployment
- can speak the languages of both research and engineering
- want to help create a world where all children learn to read well.
If this sounds like you, please apply!

Tecuity | Senior Software Engineer I | Hyde Park, UT (ONSITE preferred; will consider candidates who can commute in 1-2x/month) | Full-time | $90k-$135k
Tecuity has spent 20+ years building software for Secretary of State offices — state government agencies handling business filings and public records. Real filing deadlines, statutory requirements, and citizens who depend on the system working.
We're hiring a Senior Software Engineer I to own features end-to-end on a mature, multi-tenant .NET platform, typically supporting more than one client implementation at a time, each with its own database and release calendar.
Stack: C# / .NET 8 & .NET 10, ASP.NET Core, Web API, Entity Framework Core, MS SQL Server (heavy stored-procedure work), React + Redux front end, Git/PR workflow, Azure DevOps CI/CD.
AI-assisted development (Claude Code) is a standard, daily part of our engineers' workflow here, not a pilot program — you'll be expected to use it well and verify its output rather than just accept it.
Looking for 6+ years professional experience in C#/.NET and SQL Server. Government, regulated, or compliance-driven software experience is a plus.
Ideally we're looking for candidates who can work onsite from our Hyde Park, UT office, but we're open to Utah or Idaho candidates who can commute in once or twice a month for the right fit.

Springcraft | Manufacturing Engineer | On-site in Palo Alto, CA | Full time | $120k–$190k + equity
Springcraft is building the platform for physical AI.
Today, building robots and intelligent machines means navigating fragmented tools, incompatible hardware, and closed ecosystems. It takes too long, costs too much, and locks builders in. There is no default platform for physical AI. We're building it. Springcraft brings together purpose-built hardware, developer tools, and AI models into one open, integrated system so that builders can create machines that sense, understand, and act in the real world.
As the first manufacturing hire, you'll own how our hardware gets made, from first builds through volume production. This is a foundational, hands-on hire. You'll be on the bench and at the machines, partnering directly with our hardware engineers. You'll build the manufacturing function from zero and lead it as the company grows.

Crossref | Head of Infrastructure Services | REMOTE | Full-time | 120k USD or local equivalent
I'm the Director of Technology at Crossref and I'm looking for a Head of Infrastructure Services to join my team. This role will lead the strategy and evolution of Crossref's infrastructure ecosystem, own the infrastructure roadmap, and lead and develop our Infrastructure Services Team.
Crossref is a not-for-profit organisation that runs infrastructure that connects thousands of scholarly publishers and millions of research outputs, serving an increasingly diverse set of communities across scholarly publishing, research, funding, and beyond. Our system is a complex mix of legacy and modern components, some parts over 20 years old and tightly coupled, running on AWS with Terraform, Java, Clojure, Elasticsearch, and PostgreSQL. You'll play a key role in our efforts to modernise this system into a set of more loosely connected services.
We're looking for someone who's as comfortable getting into the weeds of cloud infrastructure as they are leading a team. If you've grown from a strong technical background into leadership, and enjoy using your technical expertise to help a team do its best work, this could be a great fit for you.
This role is fully remote, we are hiring globally, but we will need at least 2 hours overlap with European timezones.
Full job description and application form here: https://www.crossref.org/jobs/2026-09-01-head-of-infrastruct... We don't use AI as part of the recruitment process, all applications are screened by me. For any questions, feel free to message me here: https://www.linkedin.com/in/dtkaczyk/
Apex Dental Partners | Full-Stack Developer | Dallas, TX | REMOTE (US) or HYBRID | Full-time | apexdp.com
We're a Dental Support Organization running 65 practices across eight states. Dentistry doesn't sound like a technical job, but the platform behind it is: we've built our own operations system (Rails 8 + React, Electron, Go, and C#/.NET against OpenDental, all on AWS) and we're pushing hard on automation and AI to make the practices run better.
The team is small and developers own problems end-to-end. You'll figure out why a billing workflow breaks down, design the fix, ship it, and hear from the office manager who uses it the next week. Recent work includes an AI-first metrics layer that answers operational questions in chat, automated patient scheduling and communication, insurance verification scraping, and a live PMS integration across every practice. The domain is wide (clinical workflows, payroll, patient comms, revenue cycle) and there's a lot of novel work left once you learn the business. Big emphasis placed on being able to sit down with non-engineering team members and understand their workflows and build software to make it better.
Good fit if you want a stable company, a small team, broad latitude, and work that visibly matters to the people using it. We're actively building new features, not just maintaining what exists, so there's a healthy mix of greenfield work and improving a platform that's already in daily use by our nearly 1,000 employees.
Must reside in the US and be authorized to work in the US without sponsorship.

Confido Legal | Sr. Engineer | REMOTE (US only) | Full-time | $175k–$225k base
Confido Legal builds payments infrastructure for the legal industry. We're hiring a senior engineer to design, build, and maintain our software — leading architecture and product design, and translating business requirements into technical specs.
This is a broad, high-ownership role on a small team: you'll ship and maintain features end-to-end, lead architecture discussions, write clean and testable code, build automated E2E tests, do code reviews, and participate directly in company strategic planning. You'll also work closely with marketing and sales to keep technical work aligned with the business.
Stack: TypeScript everywhere, React + Next.js (mid-migration to Next.js), AWS with Pulumi IaC, Docker/ECS, GraphQL API, Figma (engineers participate in UI/UX).
We're looking for an expert in three or more of these (TypeScript required) with 3+ years of engineering experience.
~2 onsite meetings/year. Open PTO, fully paid medical/vision/dental. Apply: https://careers.confidolegal.com/careers/sr-engineer
Trax | https://www.traxtech.com/ | Onsite Cebu PH, Remote Costa Rica, Remote US are possible | Full-time | Architect
I work best as a team - with someone who can challenge my assumptions and bolster my weaknesses. I'm looking to increase the bandwidth of the architecture function at Trax, as I can't do it alone!
We BOTH need to be strong in:
- Communication - we lead by influence, not by authority. Kindness is required!
- Ego-free problem solving - good ideas come from anywhere.
- Reliable software designs - things that work on dirty data, incomplete testing, and AI-enabled development workflows.
- Building the first prototype in an area with zero guidelines - careful choices and evaluation of vendors, setting an example to follow.
You should be strong in:
- Angular, Vue, Javascript, and web serving best practices for development organizations for long term health.
- Developer enablement and tooling in the Node.js ecosystem-shared component architectures, design systems, etc.
- Data-heavy applications and their operation and security needs.
I am strong on the infrastructure, DevOps, k8s, and backend and data stacks. So don't worry about relative weaknesses there, though you will need some understanding.
This would be a good first architecture position for a Staff or Senior Staff level full-stack technical leader who wants to expand their scope. My email is in my profile!

3C Digital Solutions | Terraform Module Developer (Infrastructure as Code) | REMOTE (US) | Full-time | https://jobs.curriculo.me/3c-digital/job/a14f0ded-8f8f-49ad-...
We're a small IT consulting firm working in federal and other regulated environments. We're building a reusable Terraform module catalog: versioned, tested, documented modules published to a registry that other teams consume, across cloud, container, and virtualization environments. Module and platform engineering, not one-off deployments.
You'd own the standards: module interfaces, validation, testing, releases, deprecation. Small team, no layers, and real influence over how we build. Growing, with room to move into broader platform ownership or technical leadership.
Looking for someone who has built and maintained a shared module library other teams actually used. Semantic versioning, automated testing, input validation, policy compliance checks, CI gates. Production experience with AWS, Azure, GCP, or OCI.
Multiple positions. US citizenship required (federal contract). No visa sponsorship.

Senior Python Backend Engineer | REMOTE (EMEA/APAC)
We're looking for Python backend engineers to work on a trustless supercluster of performance-proofed GPU-enabled sandboxed docker container runners controlled by truly decentralized algorithms (not just PAXOS or RAFT).
Wow, that was a mouthful...
If you found it interesting, join Reef Technologies and tackle complex technical challenges like this on your own terms:
- Contribute from wherever you like; we are fully remote
- Set your own time commitment, as long as it's at least 30h per week
- See how we work in our handbook: github.com/reef-technologies/handbook
- Influence the way we operate through our Sociocracy 3.0 decision-making process
Salary on a B2B contract:
- 45-70 USD or 180-280 PLN per hour
- Flexible work schedule (as measured with a time tracker)
- We automatically adjust rates based on inflation twice a year
We're looking for someone with 5+ years of programming experience, including at least a year with Python (including open-source and significant personal projects).
So, what do you think? You don't even need a CV; just go to https://careers.reef.pl/?utm_source=hackernews and shoot a few quick commands to apply.
Edit: If you applied and haven't heard back, please check the spam folder of the email associated with the GitHub account you used to apply — our replies sometimes end up there.
A brilliant entry! it’s a shame I was just a bit short on the age requirement. 4 instead of 5. It would have been interesting to take the tests – I reckon they’d have been quite cool, given the design of the entry and the fact that I’d made it through to the test stage!
MIRA | Firmware Engineer | San Francisco, CA | ONSITE | Full-time
MIRA builds lightweight AI glasses that act as a second brain: they remember conversations, answer questions in under a second, translate 60+ languages, and surface useful context through a private display.

Akkio | Senior Software Engineers — FDE, Full-Stack, Backend | US (Fully Remote) | Full-time | $160k–$240k + equity | https://www.akkio.com/jobs
Akkio builds the AI platform the world's largest media agencies (Havas, Horizon Media, and others) use to run campaign workflows in production: audience building, media planning, measurement, and campaign analysis. Agentic workflows plus traditional ML, deployed on-premises inside agency cloud environments, directly on top of their data. We're ~50 people, past PMF, well funded, and growing revenue quickly.
We build agentically by default. Every engineer directs coding agents daily, and we're actively rebuilding our SDLC around that — not piloting it, not debating it. If you've felt that shift and want a team that's all the way in, that's us. We also run flat, so "senior" means ownership, not management layers.
Three roles, all $160k–$240k + equity:
* Forward-deployed engineer (FDE) — Python, TypeScript, true generalist. You embed with agencies whose systems steer billions in media spend and build whatever the problem needs: integrations, agent workflows, backend services. What you build in the field becomes product. Regular travel.
* Full-stack (web) — Vue.js, TypeScript, Node.js. You've run projects, guided architecture, and survived framework upgrades and large refactors. You care about the experience analysts live in every day.
* Backend — Python. Interesting work in at least two of: LLM systems and code generation, statistics, traditional AI/ML, large-scale data processing, distributed systems.
Details and application: https://www.akkio.com/jobs
All candidates must be authorized to work in the US.
Silkline | Software Engineer | Chicago, Seattle | ONSITE (5 days/week) | $150k-$225k + equity | https://silkline.ai
Modern hardware supply chains run on spreadsheets, email, PDFs, and prayer. It's like fax woke up in 2026. We're fixing it with an AI-first procurement platform for aerospace, defense, and nuclear manufacturing - customers include Machina Labs, Astranis, K2 Space, Castelion, and Antares.
At SmallSat last month, a supplier walked up to me (in a full spacesuit costume), said "oh you're from Silkline, we love you guys!" and handed us a roadmap item on the spot. That's the job: sit with customers, hear what's broken, ship it. 0-1 product, real UI/UX ownership, ERP integrations that sync POs and manufacturing data.
Stack: TypeScript, React, Next.js, GraphQL, Trigger.dev. You: 5+ years full-stack, startup or 0-1 experience, fast with APIs (bonus: ERPs). The role touches ITAR-controlled data, so US persons only, no visa sponsorship.
We 5x'd our customer base this past year and continue to grow fast. Small team, direct line to the founders (Isaac and myself). Also: space-suited mascot named Silky.

Statecraft | Forward Deployed Engineer (All Levels) | REMOTE (US) | $160-220k + equity
At Statecraft, we are building an AI workforce to help automate the US government. Currently our government is operated almost entirely by consultants who outnumber public servants 3:1 and institutionalize inefficiency so they can bill more hours. This only leads to agencies struggling to meet their missions, overworked and underpaid public servants, and overburdened taxpayers.
Most of what these consultants do is easily automatable: data entry, basic spreadsheet work, filling out paperwork, etc.; we do this with AI and save taxpayers ~80% on average while completing the work ~10x faster with 2-3x less errors.
We're a small, lean, mission-driven team and hiring Forward Deployed Engineers to build use cases and integrate deeply with agency customers. You'll be working with critical systems, massive surface area and national impact.
* This position requires U.S. citizenship and the ability to obtain/maintain a security clearance.

Axmed runs a live B2B marketplace connecting healthcare providers in low- and middle-income countries with pharmaceutical suppliers, working to make sure geography and income never stand between someone and the medicine they need. Backed by the Gates Foundation and Founderful. We're past proving it works and into scaling it — this role is what takes us there.
You'll design and ship autonomous agents that run real steps of the marketplace (sourcing, quoting, order matching, supplier follow-up) on real transactions and real money, with a human in the loop where risk demands it. Full lifecycle ownership: you decide the approach, build it, ship it, watch it, fix it.
Stack: Python, your choice of orchestration framework (LangChain/LangGraph/LlamaIndex/CrewAI), LLM APIs, cloud infra, CI/CD.
We are a fully remote, global team of 55. No visa sponsorship/relocation.

Puma.tech | Remote-first with PST overlap | iOS/MacOS, Android, Ai/ML, Growth | https://puma.tech
Hi all, I’m Yuriy, founder of Puma.tech. Prev. worked at Cloudant (YC S08), Meteor (YC S11), Parse (YC S11, Facebook/Meta), and explored AI/ML (computer vision for self-driving cars).
We have 2 products:
1. https://PumaBrowser.com: iOS & Android mobile browser with built in LLMs & wallets. 1m+ downloads.
2. https://PumaAI.com: small research lab focused on building private local/hybrid alternative to ChatGPT.
Open Roles: Eng (iOS/MacOS, Android, Ai/ML, Browser Extensions), Based Social Media Intern; Internships: Eng, Design, Growth
We’ve raised a few rounds from some of the best builders in ai and crypto:
Protocol Labs (YC S14), Chris Larsen (Ripple), Anatoly Yakovenko (Solana), Illia Polosukhin (NEAR Protocol), Sridhar Ramaswamy (Snowflake CEO), Jason Warner (poolside.ai, ex-GitHub CTO), Don Ho (Orange DAO, Quantstamp W18), Evil Rabbit (Vercel), John Phamous (SF Compute) and other amazing builders.
How to Apply: email careers+hn [at] puma.tech with your GitHub, a note on what you're most proud of building and what you'd like to build next.
Thank you!
Applied 2 months ago. No response
Same here, sent and email 3 times across the last 2 years, no reply
your first two application were generic and ignored the few basic questions that we ask in the posting, thus subsequent one didn't get reviewed
apologies, we've got a lot of ai-generated applications in the last few months so might have missed it. mind bumping the thread and mention `html5cat` and i'll make sure we look into it?
thank you!
found your thread – your email covers things you did, but nothing about "why Puma" or other simple questions we ask. seems like one sided, generic mass application. impressive background, but didn't seem like you care about what we're building.
I guess you found the wrong thread.
1. I received a question about my schedule (meaning: no other questions asked), I answered and received no further response. 2. I applied using your own template {a note on what you're most proud of building and what you'd like to build next}. My application was absolutely not generic mass application 3. I sent you several things I’m proud of. Among them were:
- A Product I build (independently) - linkkraft browser that captures pages/resources using chrome devtools protocol & other electron network API), basicly local-first browser. https://arestov.github.io/linkkraft-notes/trails-tree-plus-o... You are "building private, local AI in browser". This seemed specifically relevant, escpecialy if you are building a browser agent, not just a chat (like aside https://aside.com/blog/how-we-built-the-sota-browser-agent-t...).
- my open source contributions to p2p (torrent network) libraries. I did this because you have IPFS (which is p2p network) in browser.
Your application template does not contain "why Puma?" question, but spending my own time on these 2 things (local-first browser, p2p) and including them in the application was, I believe, a pretty clear answer to it.
I do appreciate you responding directly.

Quill | Fullstack SWE | Full-time | Remote, PT/ET hours preferred | $150 - 210K USD + equity | https://quill.co/
I’m a co-founder of Quill, a fullstack SDK for adding customer-facing analytics & data features to your app. Backed by YCombinator & top-tier SV-based investors (fundraising not publicly disclosed; happy to share any details when we chat).
Some examples of how customers get value from Quill: • pre-IPO fintech adds custom reporting & data export features to their money movement product. • Series B healthtech is now able to deliver completely custom in-product reports & dashboards to every enterprise customer they onboard. • Series A govtech adds analytics and reporting capabilities within their existing agent/chat product.
Reasons you’d love working with us: • Work with a small, focused, talented team on a highly technical product (by developers for developers). • Funded company in a big market, but still prelaunch with a team size <5 • High level of product ownership with tight feedback loops: the products you build are shipped quickly and get used by real customers immediately. Our latest hire built our entire CLI product from 0 -> 1, and it was used in production by customers the day it shipped.
We are growing the team to keep up with demand for new features that our customers are asking us for, while also preparing for launch. We're looking for someone that will make us better. We’re just getting started, and want you to bring your opinions, expertise, and experience to the table (not just execute on the ideas we already have).

Trustworthy Technology | Earth | Part Time | REMOTE | Vision, Marketing, and/or Design
Hi, we are a small group trying to bring the "trustworthy" feature back to tech. Curating and building a FOSS+ toolset, storefront, and eventually online service—all to support freedom, privacy, and informed consent—on device and on the net.
We've written our thoughts and research down at: https://trustworthy.technology/ and we have a few geeks starting projects at: https://codeberg.org/aol
First off, you'll notice that you've not heard about this project before. Next, the message is a bit scattered, and the "programmer art," while arguably not horrible isn't winning any awards either, haha.
That's where you come in.
You are one of the few folks who really cares about this stuff, and also a graphic/product designer, or perhaps a digital marketer, communicator or "people whisperer." (Being in the EU would be helpful as well, to work from the digital sovereignty angle, though not required.)
Some of us are unemployed and currently donating our time. Maybe you are too, or retired/cashed-out and bored. Consider this another FOSS-like project. We hope the store/service will make money, but we're not there yet.
Interested? Let's chat at: https://trustytech.zulipchat.com/join/h5usqnt2bet7exz747cbf3...
BTW, if/when you join please say hi let us know what kind of projects you're interested in.
AiMi | Full Stack AI Engineer | Remote(Everywhere) | Full-time
AiMi builds agentic AI infrastructure for capital markets: autonomous agents that ingest venue and vendor notifications, assess impact across client infrastructure, and drive change management workflows in real time, replacing what used to be manual, static processes for exchanges and their ops teams. live production platform, not a pilot.
you'd work across the full stack: React/TypeScript frontend, Node.js backend, AWS Lambda. concretely: shipping features in the agent pipeline, building MCP-based connectors and skills that extend what our agents can reach, running evals on agent accuracy and reliability, building observability and alerting for agent latency/error rates/failed workflows, and making long-running LLM, agent, and SSE calls actually resilient (timeouts, retries, circuit breakers, fail-fast, recovery). also a fair amount of diagnosing dependency/version conflicts in a Node.js/npm monorepo, which is its own skill.
looking for 2-3+ years hands-on experience, solid Node.js and REST API background, real hands-on work with LLMs or agent frameworks (Mastra, LangChain, LlamaIndex, Claude, OpenAI or similar), comfortable with AWS (Lambda, Bedrock, DynamoDB, S3, Cognito, API Gateway, CloudWatch), MongoDB/DynamoDB, and genuinely tests what you ship (unit, integration, e2e). familiarity with spec-driven development (Claude Code, Cursor, CodeRabbit or similar) is a real plus since that's how we work day to day. bonus points for capital markets/trading infra background, LLM observability tooling like Langfuse, SSE streaming experience, or PostHog.
you'd be working on great things here: real architectural decisions at an early-stage company, visible impact from week one, and room to grow into a senior or lead role as we grow.
apply: https://join.com/companies/aimitechnology/16658631-agentic-a... , or reach out directly at vishnu.swaroop@aimi.technology
I see you're looking for a Full-Stack AI Engineer with experience in Node.js, AWS, and LLMs. Let's get started.
I'd focus on building robust, resilient agent pipelines and LLM integrations. I'd start by evaluating and improving the agent accuracy and reliability. I'll also build observability and alerting for agent performance. I have experience with LLMs and agent frameworks, and I can help ensure your LLM calls are resilient. I can also assist with diagnosing and resolving dependency and version conflicts in your Node.js monorepo. I'll bring this experience to the table, and I can share more on my approach in our next conversation.
What specific areas of your agent pipeline do you want to improve first?
Snout https://snout.com/ | Multiple Engineering + Product Roles | Remote US or Ontario, Canada | Full Time
Join us at Snout on our mission to ensure no one ever has to make a health decision for their pet based on the cash in their bank account. Snout plans pay for 100% of routine veterinary care, unlimited visits, and additional member benefits - think pet insurance, that you will actually use every year.
We're growing the team and hiring across the board. Open roles:
Full-Stack Software Engineer - Build and ship every day across our web apps, payments, and data systems, from database to UI.
Across all roles we're looking for at least three years of relevant experience, and we're hiring senior and staff level engineers as well.
Our tech stack includes Node.js, React, PostgreSQL, AWS, Tailwind, and Python. We use both JavaScript and TypeScript heavily. Our team uses LLM-based tooling day to day, but we're fundamentally a human-centric team, and our product itself does not heavily feature AI components.

Looks like they have an accidental “d” at the end of the link.
Remove that and you get https://jobs.gem.com/snout
I imagine it was a mitigation measure against botspam slopping it up in Snout's candidate pool.
Or maybe a typo, still, I'd have left the link unstated.

I find it hard to imagine that would be the case. They already link to the same page from their website without any typos, and they link to their website from the comment here.

NetBird | Berlin, Germany (or remote, CET/CEST overlap) | Full-time https://netbird.io/careers
NetBird is open source networking and access control WireGuard-based overlay networks with zero-config peer-to-peer connectivity. Open source, built in Europe, used by thousands of teams worldwide. We're a small and growing team going up against the incumbents in network security. Post Series A.
- Engineering Manager : You will take a huge part in leading and scaling our engineering org. Unblocking, scaling, hiring, you'll still read code and hold technical opinions that impact the product. We're not looking for a pure people manager. Networking/infra background is a plus, not a filter. If you've scaled a team from 0 to 20+ and seen your product scale too, I'd love to talk to you.
- Senior/Staff Backend Engineer (Golang) : the control plane: peer coordination, policy and access control, multi-tenancy, and keeping it all fast as customer networks grow into the hundreds of thousands of peers.
- Network / Client Engineer (Golang) — the agent side: WireGuard, NAT traversal and hole punching, relays, DNS, and shipping one client across Linux, macOS, Windows, iOS and Android. If you enjoy debugging why one connection out of a thousand won't go peer-to-peer, this is the role.
- Solutions Engineer — technical, customer-facing, pre/post-sales. You'll be the person who architects a rollout for a 500-person company's network live on a call, and a great channel back into the roadmap.
We have an office in Berlin and mostly work CET/CEST. We'd love to have you in the office with us, but if your experience is stellar we're happy to hire remote. We're scaling quickly, so this is a chance to join early and scale your career as well as with the company.
Apply at https://netbird.io/careers, please mention you found us on Hacker News in your application.

G-Research | https://www.gresearch.com | London UK, on-site | Full-time
G-Research is a leading quant finance company. Big compute farm, interesting problems.
My team is hiring senior engineers to work on our (actually world class) DAG scheduling infra for distributing research and production workloads across the compute farm. What we do is roughly:
* maintain and improve the SDKs for that scheduler in Python, F#, and C#
* add interesting new features to the scheduler itself
* maintain and improve a web backend and UI for quants and engineers to monitor their jobs, increasingly with high availability requirements
* translate bidirectionally at the business level between low-level infra providers and quant/ML researchers
Some functional experience preferred, because our core product is in F#. Lots of dealing with very smart researchers and engineers, with the kind of fun problems arising when you run large ML workloads at scale.

Mastra | Customer Engineer | REMOTE (AMER or EMEA time zones) | Full-time
Mastra is the open-source TypeScript framework for building AI agents (agents, workflows, memory, evals, tracing). From the team behind Gatsby, YC-backed,https://github.com/mastra-ai/mastra
We're hiring a customer engineer. Some companies would call this an FDE; we don't, because roughly half the job is shipping in the framework itself. The other half you're embedded with paying customers deploying agents to production: in their Slack channels and on calls, writing code in their repos, reviewing their PRs, working through architecture with their engineers. What you learn there comes back as bug fixes, features, and new primitives in Mastra. One of our current customer engineers is among the top bug-fixers in the entire codebase.
You should be a full-stack TypeScript engineer who has built agents and who can explain technical decisions clearly to engineers who haven't seen your code.
Remote. We have a lot of EU customers and response-time SLAs, so US Eastern/Central or EU hours work best.
Process: a call with Shane (co-founder/CPO, leads customer engineering), a conversation with a customer engineer, a 2-3 hour take-home, then you present it to us and get feedback.
Apply: {https://jobs.ashbyhq.com/Mastra/05172cb0-47ec-44f9-9fe8-07d4...} We get back to everyone.
ORIGAMICS | Founding Researcher | San Francisco | ONSITE/REMOTE
Origamics is building AI models that reason about electronics and help turn schematics into production-ready boards.
We’re looking for a Founding Researcher to work directly with the founders on physics-informed models for Electronics design — physical behavior, simulation, and scientific ML. You’ll tackle open-ended research problems, push models from experiments to production and real hardware, and have the opportunity to publish novel research along the way.
You’ll likely be a good fit if you have strong ML/research fundamentals, enjoy 0→1 problems, and have experience with scientific ML, geometric deep learning, numerical methods, simulation, EE, or applied physics. PhD is a plus, not a requirement.
Apply: https://www.origamics.ai/join-us?ashby_jid=7acf3a2d-46a5-420... (Mention HN when applying.)
OpenAlex | Software Engineer | Remote | Full-time | $150–200k USD

We're hiring two engineers to work across the whole backend, which is SQL and PySpark on Databricks, Python/Flask APIs, Elasticsearch, and Cloudflare Workers. It's a small team with lots of autonomy. You'll notice what's missing, build it, ship it, and answer the tickets about it. We're AI-native, with agents writing all of our code.
Apply here: https://openalex.org/jobs/software-engineer
"What will you do in your first week?"

Mingla | CTO (ONSITE, Stockholm) or Part-time Engineer (REMOTE ok) | https://mingla.com
Mingla makes strangers meet at in-person events: attendees scan a QR code and are straight in — no App Store, no signup — gamified missions start real conversations, and the organizer gets proof of what happened in the room.
You'd own the platform end to end: Elixir/Phoenix backend (Ash, GraphQL, Postgres) and a native SwiftUI iOS app — the QR entry is an App Clip. We're open to two setups: a full-time CTO onsite in Stockholm, or a part-time engineer who can work remote.
Apply: hello@mingla.io, subject "HN: CTO / Engineer", with a link to something you've built and one line on which setup fits you. No cover letter needed.
Biobase | Senior Technical Product Engineer, Technical Product Engineer (Early Career) | REMOTE (US, Canada) | Full-time | $150–230k / $90–170k + equity
Biobase has grand ambitions. We broker biospecimens, whole slide images, and the clinical metadata attached to them, on a supply-chain backbone that we're steadily automating. We’re building healthcare-data-focused agents on top of the datasets that we’re assembling, too.
We'd rather build the thing that removes the work than throw people at it. Two roles, one team, both reporting to the CPO:
Senior Technical Product Engineer ($150–230k + meaningful equity). The product team's technical interface. Architecture decisions and code review on the platform (Python/FastAPI, TypeScript/React, Postgres, Azure); the data pipeline and informatics that take specimen, slide, and clinical data in from suppliers and labs; and product ownership of the internal platform that builds our agents (permissions, evals, cost control, guardrails for sensitive data). You've been the reviewer of record somewhere, you've operated what you shipped, and you think in business problems before tickets.
Technical Product Engineer, early career ($90–170k + equity). Same territory at an earlier stage: the platform, the data pipeline and informatics, and the agents we run against our own operations — with a senior product engineer and our lead engineer reviewing your work and pairing when it helps. Open on background – self-taught, bootcamp, degree, research lab, a career you're leaving – selective on the bar. You've built something and someone else used it.
We build with Claude Code every day and expect you to become both fluent with it and skeptical of it. No ticket queue, no spec handed to you. Comp is salary + equity combos you choose between.
Full postings: https://biobase.ai/careers
To apply: email jobs@biobase.ai with something you built that eliminated manual work and what happened after it shipped. Links over resumes, no cover letter.

Odin builds workforce visibility and compliance software for critical infrastructure. We’re deployed on 500+ active projects with 100K+ workers, securing more than $100B in construction value.
Senior Design Engineer — Own interfaces from UX and visual design through production React. You’ll establish our design language and design system, prototype interactions, and ship responsive, accessible frontend experiences. We need someone who genuinely designs and codes.
Senior Platform Engineer, Edge Systems — Build software connecting cameras, access-control readers, rugged devices, and local compute to our cloud across unreliable networks. Work includes protocols, real-time streams, buffering and synchronization, remote deployment, diagnosis, and recovery.
Out stack: TypeScript, Node.js, GraphQL, Postgres, Kubernetes, GCP, React, React Native.
Both roles are US-remote with periodic jobsite travel. US work authorization is required.

Senzing (entity resolution SDK) | Platform Engineer | Remote (USA) | Full-time
Senzing builds enterprise entity-resolution SDK technology — an embeddable library that runs entirely inside customer infrastructure with zero data exfiltration. We're hiring a platform engineer to own the AWS infrastructure behind Placekey (our location-data subsidiary), a production API service running at scale.
Day one, this is a cloud/platform role: you'd own the operational health of Placekey's stack, close out post-migration hardening, and have real input on where the infrastructure goes next. Over time the role grows to include internal IT and systems work (Active Directory, endpoint/laptop provisioning, Tailscale, security) — so we're looking for someone who's happy owning things end to end, not only the glamorous layer.
Stack: EKS Fargate, Aurora PostgreSQL, S3, Lambda, Cloudflare, API gateway (Kong/AWS), Terraform, Grafana/CloudWatch/Datadog. Apps are Scala and Rust.
Looking for: 5+ years platform/cloud infra, production Kubernetes (EKS ideal), managed Postgres (backup/recovery/tuning), IaC, solid networking, strong Python/Bash. You don't need to be an expert on the IT/systems side today — but you should want to grow into it.
Remote anywhere in the USA. Competitive salary, full health/dental/vision, 401(k) match, flexible PTO.
To apply: email enghiring@senzing.com with your resume and a short note — tell us about a challenging production system you've owned end to end, including an incident where your monitoring missed something and what you changed afterward.
Klassif.ai | ML/AI Engineer | Hybrid (Leuven, Belgium; remote 3 days/week)
We started off naively as just another intelligent document processing SaaS. Years of experience have shown us where the real pain points and value lies. Join my AI team and be horrified by how many critical business processes rely on email. Then help me execute on our ambitious roadmap!
If you find yourself nodding along with the following statements, you may be a good fit:
- You enjoy getting your work into the hands of users
- You’re okay debugging a stray tensor in the morning and designing services in the afternoon
- You care about the field of AI and interact with its community
- You can ‘sense’ when a loss curve is doomed
- You’ve fine-tuned LLMs, even just for fun
- You’ve been thinking a lot about agents lately, for some reason
- You don’t mind the odd bit of customer support (it’s where we get our best insights!)
All credentials welcome, including recent graduates. We’ll shape the role around you. What matters is creativity and visible engagement with the field.
Who may apply: EU citizens or holders of a Belgian work permit. (Everything else is more admin than we have time for.)

Checkly | https://www.checklyhq.com | Product Manager, Sales Engineer, Senior Sales Engineer | REMOTE (Europe / US Eastern) | Full-time
The best developers don't wait for a customer to tell them something's broken. They catch it first, in the pull request, in staging, or in the checkout flow at 3am, before a single user notices. That instinct is Checkly's whole reason to exist. We give developers and their agents the tools to own reliability the way they own their code: monitoring defined as code, powered by OpenTelemetry and Playwright, versioned and reviewed like everything else they ship. From pull request to post-mortem, in one place.

Reframe Systems | Boston, MA | ONSITE or HYBRID | Full-time
We're creating housing on a mass scale through a network of robotic microfactories producing highly-customized buildings, from ADUs and cabins through townhomes and mid-rise apartments. We build with industrial efficiency while making buildings for an exact footprint, scale, style, and level of finish to fit any market, regardless of how tight the site or the zoning.
The core software problem is producing buildings designs without the typical months of design development and engineering. You can design natively in our building system or import existing designs, taking in a high-level architectural schematic and using that to generate a detailed manufacturable 3D model of the building (every stud, sheet of OSB, nail, electrical outlet, etc.) used to drive professional engineer review, permitting, and production. A compiler for a building.

Xaira Therapeutics | Midlevel/Senior/Staff Engineers | Seattle or SF
Xaira Therapeutics is developing biological foundation models (not LLMs) to hit undruggable targets and cure disease. We've put together an incredible cross-disciplinary team of pharma veterans who have brought drugs to market, drug designers/AI scientists from Nobel laureate David Baker's lab, and engineers from tech in order to meet the moment and build a company to reimagine how drugs are made in the pursuit of better medicines. We're not a SaaS company, and the ultimate goal is to see the medicines we make delivered to patients.
I lead the engineering team and am hiring across multiple teams. There's:
- Research Engineering: work on a modeling team with the goal of making a model better. You think in tensors, understand what makes a kernel fast, and obsess over training throughput.
- X-Scientist: building an agentic copilot for drug development with access to our internal suite of tools. You have backend experience, have built tools for agents to interact with, and enjoy tinkering with agent harnesses.
- Data Engineering: we generate large volumes of data from our lab that provide critical feedback loops to our modeling efforts. You either hate or love lakehouses, have a preferred ETL orchestrator, and are intrigued by the problem of capturing data off of lab instruments.
- ML Platform: boy do we have some GPUs for you. Modeling teams need productive compute infrastructure, job scheduling, and numerous other affordances so that they can "just focus" on the model. You shudder at the words "falling off the bus", you have an opinion on how checkpoints should be recorded, and you've built tools that improve the modeling lifecycle.
Send me an email to apply: justin.yan@xaira.com Include a resume and tell me about something you've built that illustrates your skills.
Legile | Senior Full-Stack AI Engineer (CTO track) | Antwerp, Belgium | HYBRID | Full-time | Belgium-based only
Legile builds OneView, a legal AI platform that legal teams use in production for contract review, risk and compliance. We recently joined the Anchr software group and are scaling from proven MVP to production-grade platform.
You join as the third person in the team, next to the two founders, and take technical ownership of OneView: retrieval (PostgreSQL/pgvector), LangGraph pipelines, FastAPI backend, React/TypeScript frontend, plus the CI/CD and observability that let a small team ship with confidence. As the team grows, the role grows into CTO.
We care more about AI-native workflows you have shipped to real users than about ticking every box on a stack list. Real R&D backed by a Flemish innovation grant (VLAIO).
Stack: Python/FastAPI, React/TypeScript, PostgreSQL + pgvector, LangGraph, Azure.
Apply: jobs@legile.be. No cover letter, just tell us what you built.
Snowflake | Forward Deployed Engineer, Product Manager | Menlo Park, CA | Warsaw, Poland | London, UK | ONSITE
I’m part of Snowflake’s Applied AI / Forward Deployed Engineering team, and we’re hiring for multiple roles on the team.
We work directly with strategic customers to design, build, deploy, and improve production AI systems on Snowflake. That includes LLM applications, RAG and agentic workflows, evaluation frameworks, guardrails, observability, and production iteration using Snowpark, Cortex, and Snowflake’s native AI capabilities.
For the FDE role, we’re looking for strong engineers who can build and ship customer-facing AI systems end to end, especially if you’ve worked on LLM apps and care deeply about evals and quality. For the Senior role, we’re looking for someone who can lead multi-engineer AI engagements, mentor other engineers, and still be hands-on in architecture and implementation. The roles are customer-facing and involve travel, including at least 25% onsite time with strategic customers.
If you like working in ambiguity, building real AI systems instead of demos, and partnering closely with customers to get things into production, these roles are a good fit.

Starlight | Senior Full-Stack Engineer | REMOTE (US), NYC preferred
I’m the Head of Engineering at Starlight, and we’re hiring a senior full-stack engineer.
We build software that helps financial institutions connect people with government benefits they’re eligible for. More than $100B in benefits go unclaimed every year because the underlying systems are fragmented and difficult to navigate. We’re trying to change that.
Our engineering team is intentionally small, so this is a high-ownership role. You’ll work across the stack, help shape our architecture and engineering culture, and have significant influence over how and what we build.
One area I’m especially excited about is building an “AI-first” engineering organization. I put that in quotes intentionally because I don’t think the industry has figured out exactly what it means yet—and neither have we. I want this person to help me figure it out.
I’ll encourage experimentation and use of AI, and we’ll have lots of conversations about what works and what doesn’t. But I’m not setting token quotas or mandating that people use AI for everything. I care much more about figuring out where it genuinely makes us better.
I’m actively involved in the hiring process and happy to answer questions about the team, role, or company.

Hiya | Senior Backend Software Engineer | Seattle, WA | HYBRID | Full-time | $113-197k + equity
Hiya's Voice Intelligence Platform protects 500M+ users from spam, fraud, and deepfake scam calls, and gives businesses branded, verified caller ID so the calls that matter get answered.
We're hiring a senior backend engineer for a small foundational team building our next-generation voice products from scratch: real-time SIP/RTP media handling, STT/TTS pipelines with tight latency budgets, deepfake detection and speaker verification, and conversational AI, all integrated directly into carrier networks. It's greenfield, so you'll be making the early architecture decisions, not maintaining legacy services.
Stack: TypeScript/Node.js, Python, Kafka, Docker/Kubernetes on AWS. Telephony experience (SIP, RTP, WebRTC) is a plus, not required. Team is distributed across Seattle and Europe, async-first; 3 days/week in the Seattle office.

InfoHawk | Software Engineer | London, UK or NYC | REMOTE (UK or US), occasional onsite | Full-time | https://www.infohawk.com
Fraud reaches people through ads, cloned brand sites, counterfeit shops and AI-generated video, and it moves faster than any manual review. InfoHawk detects it while it is still running, correlates it across platforms and formats, and surfaces it early enough for our customers to act. We are a small team of engineers plus security, privacy and fraud specialists. Pre-seed, $2.25M led by Moonshots Capital: https://www.infohawk.com/news/2026-06-08-pre-seed-funding-an...
You’d own how data gets in: scrapers and collectors that survive source changes, official APIs where they exist, undocumented endpoints where they don’t. Sources break constantly. Can you figure out how to use AI to spot the change and adapt automatically? Stack: TypeScript, Node, SvelteKit, Postgres, Playwright, heavy AI-assisted development.
We’re looking for ~3-5 years building scraping or integration systems in production, but if you’re a great engineer who doesn’t tick every box we’d still like to hear from you. UK-based for London, US-based for NYC; we cannot sponsor visas. Two of our three founders are engineers, one in each city, and you’ll work with them directly.

Cardog | Toronto, Canada or REMOTE | Full-time https://cardog.app/careers
We're the system of record for the Canadian vehicle: raw automotive data turned into facts that can be checked. Our open-source VIN decoder sits underneath a government vehicle registry.
Some of what's interesting:
- A government registry, a manufacturer's own filing, a listing site and an insurance record will describe the same truck four different ways, and nothing in any of those files says they're the same truck. Reconciling that, for every vehicle in the country, in a way that holds up when a regulator asks how you know, is most of the data work.
- Seventeen characters on a door frame encode manufacturer, plant, model year and build attributes — badly, inconsistently, and differently per manufacturer. Public reference data covers some of it. The rest gets worked out from filings, recall documents, and patterns inferred across millions of vehicles.
- We read vehicles directly over OBD-II now. Forty modules answered on a recent Hyundai, each reporting its own part number and installed software version. Nothing downstream of the VIN moves when a module is reflashed, so no registration, history report or dealer system knows what software is actually in a car.
Hiring: VIN Decode Engineer, Data Platform Engineer, Infrastructure Engineer, Founding Engineer (dealer platform). TypeScript, Postgres, Cloudflare Workers.

Pagelove | https://pagelove.com | Founding Software Engineer | REMOTE | Full-time | $110k–$130k + early equity
Pagelove collapses the modern web stack into its simplest form: no databases, no APIs, no application servers. Just HTML that works like an app, scales like a CDN, and is AI-native by design.
The page becomes the application, API and persisted state. Humans and machines can read and update the same surface directly using CSS selectors over HTTP, rather than through separate HTML and API/MCP interfaces. With Pagelove, AI can finally build web applications without having to deal with the complexity of the full stack.
We’re seed-stage and well-funded, hiring our first non-founder engineer. The codebase is Rust, with work including distributed storage, HTTP caching/ETags, CRDTs, parser/DOM performance, CI and production infrastructure.
Our development process is heavily agentic: Claude Code and Codex do substantial implementation work, with humans focused on architecture, review and the hard problems.

Noricum | Senior Backend Engineer, Payments, Ledger & Provable Fairness | REMOTE (2h overlap with US Pacific) | Contract to permanent | $120-160/hr | Start by 14 Sep
I'm the founder of Noricum where we build platforms – currently the money infrastructure, ledger, engine and payment rails behind a pre-launch wagering platform with a Steam skins economy. The games, a cashier and a bet ledger are built and live as a front end, with written specs for the server contract: ledger schema, refusal table, round lifecycle, every game's arithmetic. Processing and licensing are secured. The server does not exist. That is the job. You would own:
- A server-authoritative game engine - seeds, nonces, outcome computation - A double-entry ledger where balance is derived and no client write can change it - Server-side enforcement of every limit and refusal - Payment rails idempotent under duplicated webhooks - Seed custody and the provably-fair lifecycle - An affiliate system with referral attribution and commission payouts
Must have shipped: a double-entry ledger or equivalent money system in production, a payment integration including webhook idempotency, auth and sessions you built and operated, and infrastructure you owned end to end. Provably-fair systems, settlement-side gaming or trading infra, or Steam trade automation all stand out.
Email michael@noricum.io with your start date and a few lines on the last money system you shipped - what it guaranteed, and how you knew it held.
Source (https://source.inc)| USA/Canada: REMOTE | Full-Time
Our mission: make handling memory, state, and context for AI agents outside the cloud as simple as it is in the cloud. Today it isn't close. An agent without data is inert, and outside the cloud, data is duct tape.
An agent in the field needs data that is verifiable, auditable, concurrent, collaborative, and permissioned. No single system gives you all five. SQLite gives you local storage and nothing else. Every other database assumes the cloud is there to provide the rest.
We're building the data layer agents actually run on: local-first, syncs peer to peer, every write verifiable, every read auditable, no cloud required. The stack is open source: https://github.com/sourcenetwork/defradb. We think it's the best memory an agent can have, bar none.
We’re growing fast and are looking to fill the following positions:
-Chief of Staff - https://source.network/careers/chief-of-staff
-Growth Hacker, Developer Adoption - https://source.network/careers/growth-hacker-developer-adopt...
-Head of Business Development - https://source.network/careers/head-of-business-development
Vitalize | Senior Product Manager or Staff Product Manager | San Francisco (hybrid)
What we do: Hospitals run critical operations (staffing, labor planning, and capacity) on spreadsheets, phone calls, and gut instinct. Labor is the biggest cost and hardest operational problem, and it’s still largely manual. Vitalize is building the operating system for hospital labor (and ultimately capacity): we forecast demand from real hospital data (e.g., ADT + historical patterns + acuity) and translate that into concrete staffing decisions: next month’s schedule and the next shift.
Traction: - ~$37M raised - Launched 2024; ~$13M committed ARR across 10+ health systems - Live in 20+ hospitals and growing quickly
The role: We're hiring a PM to own the product experience that takes a hospital from signed contract to successfully using Vitalize in production. Getting there is complex: every health system has its own HRIS, scheduling workflows, union rules, and technical environment. This team builds the custom integrations and internal tooling that make those deployments faster, more repeatable, and less manual as we scale.
We're looking for a PM who... - Led messy third-party enterprise integrations deep enough to make real technical calls with eng - Has built internal tooling with an internal team as the customer - Prioritized a roadmap under live GTM pressure and held the line when the loudest deal wasn't the right build - Startup experience, where the system you were building didn't exist yet
If you're interested, email me mark@vitalize.care

Astronomer | https://astronomer.io | NYC preferably, open to remote | Full-time
Hiring for ~10 eng roles listed at astronomer.io/careers, but the focus is specifically on distributed systems, observability, and applied AI.
Astronomer is a primary contributor to Apache Airflow and offers our customers a managed Airflow service with a similar business model as Databricks with Spark or Confluent with Kafka. Our tech stack is primarily Go, Python, and TypeScript. The problems we work on generally center around (1) building out our commercial managed Airflow offering, (2) building a data + infra observability stack on top of Airflow, and (3) building AI products and experiences that are genuinely load-bearing and additive to our customers experience on the platform.
We're also starting to write more about the work we're doing, this is pretty representative: https://www.astronomer.io/blog/astro-airflow-re-engineered-f...

Brilliant.org | Senior/Staff Software Engineer (Interactives) | Remote (North America), SF, NYC | Full-time | $180k-$250k | https://brilliant.org
Brilliant is building the world's first graphical AI tutor: a collection of interactive learning experiences that both the learner and their AI tutor can see and manipulate. In a world of cognitive offloading, Brilliant's AI gets people to actually think and solve hard problems.
We're hiring an interactive-focused engineer to craft the building blocks that power it. Each interactive exposes an API used by learning designers, our authoring agents, and the tutor itself. And every configuration those APIs can produce has to be a correct, solvable, meaningful puzzle. It's a tricky technical problem with a big payoff for our learners.
Engineers at Brilliant think about both "building the right thing" AND "building the thing right" while pursuing high standards of excellence for ourselves, our product, and our codebase.
If you're energized by the prospect of doing the best work of your career and changing how the world learns, you can learn more and apply here: https://brilliant.org/careers.

Mondrio | Founding Product Engineer | San Francisco | ONSITE | $200k – $250k plus equity
Mondrio (https://mondrio.io) builds agentic pricing management: AI agents plus pricing experts that keep B2B pricing current rather than a one-off, one-time exercise. The founding team ran 150+ pricing engagements before starting the company and are translating that expertise to shape the next frontier of pricing in the agentic era.
The role comes with significant scope and high autonomy. You will own the full product lifecycle: customer discovery -> rapid prototyping -> agent-ready specs -> shipping via agentic orchestration -> o11y and evals -> growth & expansion.
Here are some domains you will ship: - Multi-agent simulation to emulate the behavior of a buying committee - A2A pricing interactions governed by OPA/Rego policies defined from natural language - Generative UX driven by a MCP server with full system capabilities access - Autonomous quote generation and real-time deal intelligence during sales calls
We don't have PMs or product designers so you serve as the product bridge between the founders, pricing experts, and engineering. If you're a mature engineer, looking to work with a very senior/staff team across the stack: customers, models, server, clients (web, TUI, chatbots), evals, then this is the role for you. In short, the role is ideal for someone who has significant product engineering expertise and has sharpened their SDLC competency to be AI-native.

Deya | Multiple Roles | New York, NY | HYBRID (NYC) or REMOTE | Full-time | https://deya.health/careers/
Everyone in health AI is chasing scribes and diagnostics. Almost no one is building the longitudinal data layer that captures what actually happens to patients over time. That is the real moat, and we are building it for eye care.
Deya sits between doctor and patient, capturing symptoms, treatments, outcomes and ocular images over time. Clinician-led, piloting with eye doctors, and we hold the largest dataset of eye images captured on smartphones. We build with AI tools daily.
Three roles, all high ownership:
Software Engineer (AI x Healthcare) - Product and infra from 0 to 1. Next.js, backend, cloud, agentic workflows, longitudinal clinical data.
Mobile Engineer (React Native, Swift, Kotlin) - A modern phone is already a clinical instrument and almost none of it has been pointed at eye care. Own the app and its UX end to end.
AI Engineer (Computer Vision + LLMs) - Own the vision pipeline turning phone photos into clinical signal, plus the LLM systems reasoning over patient history.
We have a proprietary clinical dataset and because we control capture, you can improve the data itself rather than model around its limits. Optometrists and ophthalmologists in-house to define ground truth and validate the work. Competitive salary plus equity.
All three roles and apply: https://deya.health/careers/
Odyssey | Sr. Security Engineer | Full-time | Remote (US) or NYC
Odyssey is building the leading financial technology platform for school choice. We help families access funding for tuition, tutors, curriculum, software, and enrichment programs—empowering them with greater educational opportunities.
We’re well-funded, backed by top investors including Andreessen Horowitz (a16z), and we are rapidly scaling.
As Odyssey's first Security Engineer, you'll have full ownership of our security posture — shaping strategy, building programs from the ground up, and driving best practices across our entire technology stack and product suite. This is a high-impact, high-visibility role where your decisions will directly influence how we protect our customers, vendors, and employees.
You'll partner closely with cross-functional teams to embed security into everything we build and ship, champion solutions to emerging security challenges, and ensure we stay ahead of an evolving threat landscape. You're someone who embraces AI tools to work smarter — whether that's accelerating threat detection, streamlining vulnerability analysis, or improving how we respond to incidents.

Newtwen | Backend & Cloud Platform Engineer | REMOTE (EU) | Full-time | €70k–€90k+
Newtwen is building a cloud platform that brings complex physics and data-driven intelligence directly onto microcontrollers, generating ultra-fast runtime firmware that executes in just a few microseconds.
We're looking for a Senior Backend & Cloud Platform Engineer to help architect and build our first production-grade cloud backend from the ground up. You'll own backend services and computational pipelines spanning 3D geometry processing, mesh generation, model order reduction, calibration and neural network training.
A core part of the platform is dedicated to data-driven modeling, with a specialized neural-model library designed to make physical models adaptive in real time.
You might be a good fit if you have: strong production backend/cloud experience, Python (FastAPI or similar), relational databases, Docker, cloud infrastructure (GCP preferred), CI/CD and IaC — and enjoy making architecture decisions rather than just implementing tickets.
Location: REMOTE (EU), with the option to work hybrid in Italy Compensation: €70k–€90k+, depending on experience
Apply: career@newtwen.com — mention Hacker News and include your LinkedIn/CV and, if available, GitHub or project links.

ODK | Senior Product Manager | Remote (Worldwide) | Long-term contract, 30–40 hours/week | $90–$110/hour USD
ODK is an open-source platform used by thousands of organizations worldwide to collect billions of data points for disease surveillance, supply chain traceability, environmental monitoring, and more. It enables users to build powerful forms and reliably collect structured data, even in places with little or no Internet connectivity.
ODK has been actively developed for 18 years. We have a mix of self-hosted and SaaS users across many sectors. We're looking for a senior product manager who will own product discovery and prioritization across this diverse user base. To be successful, you'll need to find the common needs behind very different workflows and turn them into opinionated product improvements.
Because the team is small and the user base is large, this is a high-autonomy role where product decisions have an unusually direct impact. You should have substantial experience managing complex B2B or technical products. Experience with open source, self-hosted software, and small, fully remote teams is a plus.

Balerion AI | Software + FDE + AI Engineers | San Francisco, CA | ONSITE | Full-time | $250k+ base + seed equity | Visa sponsorship available | https://balerion.ai
We're building agentic AI for mortgage lending — automating document processing and income qualification for loan originators.
Underwriting a loan means pulling numbers out of a few hundred pages of paystubs, W-2s, bank statements, and tax returns, then applying underwriting guidelines that run to thousands of pages of edge cases. Most of it is still done by hand.
Problems we actually work on: routing scanned pages to OCR vs. text extraction when the text layer is unreliable; extraction pipelines where a wrong number is much worse than a missing one; running long agent workflows durably so a failure three steps in doesn't restart the whole loan; and evaluating multi-step output against guidelines that are themselves ambiguous. We put real effort into eval infrastructure, because "the demo looked good" does not survive contact with a lender's compliance team.
Stack: Python, PydanticAI, Restate for durable execution, Postgres, AWS. Frontier models from OpenAI and Anthropic plus open-source models where they win on cost or latency.
We raised an $8M seed led by Kleiner Perkins and have paying customers in production. Team previously at Snowflake, PayPal, Twitter, Atlassian, and Microsoft.
Comp: $250k+ base, meaningful seed-stage equity, 5% 401(k) match, full health coverage, commuter stipend, gym membership, daily office breakfast & lunch. Full relocation to SF covered.
Onsite in SF. Visa sponsorship: yes.
Email vishal@balerion.ai with "HN" in the subject, plus a resume or GitHub.

Shepherd (Series B) | ONSITE | San Francisco, CA
At Shepherd, we're pursuing the most ambitious technical vision in commercial insurance: fully autonomous underwriting. Shepherd is an AI-native commercial insurance platform transforming how high-hazard industries get covered.
The infrastructure behind the AI boom (data centers, semiconductor fabs, renewable energy assets) has to be built and insured, but traditional carriers weren't built for this speed. We built Shepherd to solve that.
We announced our $42M Series B earlier this year! That brings our total funding to over $60M — led by Intact Private Capital, the investment arm of one of the largest insurers in the world. Intact is not only our lead investor but also a carrier partner, a testament to the confidence the incumbent industry has in what we're building.
We’re looking for product-minded, high ownership engineers to join our team! The Engineering team is HQ’d in SF, but we’re growing in NYC now too!
We’re hiring for 4 Senior SWEs, 1 MLE and 1 AI PM in SF, and 2 Staff SWEs in NYC. Engineers own projects end-to-end so full stack ability is expected.
Check out our open roles here: https://shepherdinsurance.com/careers

Lokker.com | Data Scientist, Classification and Scoring | REMOTE: North America / Europe, UTC-8 to UTC+2 | Full-time
Lokker is a privacy platform. We continuously analyze websites, applications, third-party technologies and data flows to identify privacy, security and consent risks in production. We have built a large proprietary dataset from years of observing real-world digital behavior, and we are hiring a data scientist to help us expand and improve the classification, scoring and risk intelligence built on it.
You will develop and improve models that classify digital activity, identify meaningful privacy and security behaviors, and assess the confidence and significance of findings.
Looking for 2 to 4 years of production experience in data science and machine learning. Strong Python and SQL, pandas or Polars, scikit-learn and modern classification techniques, familiarity with model evaluation and explainability. Practical experience in training and evaluating supervised classification models on real PRODUCTION data, practical LLM experience beyond simple demonstrations, and curiosity about how websites and internet technologies actually behave. You do not need a privacy or adtech background. We will teach the domain.
You will work closely with engineering, product and privacy experts, and what you build goes directly into the product.
IMPORTANT: the timezone range above is a hard requirement, not a preference. We cannot make an exception.
ON APPLICATIONS: we assume you used AI to help write it. So do we. What we cannot do is verify a claim that exists only in the document you sent us, so make sure the skills you claim are visible somewhere public: LinkedIn with real dates and role detail, GitHub, papers, Kaggle, a writeup, a talk. If your best work is under NDA, say so and describe it in your own words.
A human reads every application. No keyword filter, no automated rejection.

CyberAtlas | https://cyberatlas.ai | Software Engineer | REMOTE Worldwide | Full-time
CyberAtlas maps the internet to help security teams, enterprises, and governments discover and understand their exposed digital infrastructure.
We’re hiring a Software Engineer to build internet-scale systems processing billions of domains and websites.
You’ll work on backend services, data pipelines, search, fingerprinting, vulnerability detection, malware detection, and performance optimization.
Looking for strong Python (Flask/FastAPI) and/or Go experience, large-scale data systems, OpenSearch/Elasticsearch, Redis/LMDB, MongoDB/Postgres, Docker, and production systems.
How to apply: Email atlas@cyberatlas.ai with your CV and, as a simple anti-bot check, include:
1. The query you ran on Finder (https://cyberatlas.ai/finder)
2. The first-page results returned by that query

The part that really caught my attention is the data/system problem underneath this: internet-scale discovery, fingerprinting, deduplication, search, detection, and keeping the resulting infrastructure model continuously useful despite noisy and changing data.
That's a much more interesting engineering problem than a typical “security product” role.
I'll complete the Finder challenge and include the requested results in my email.

Sunspell | Founding Engineer | New York, NY | ONSITE | Full-time | https://sunspell.fm/careers/founding-engineer
Six-person venture lab in New York. Part lab, part studio, part operating system, building original products and the systems behind them. Compounding every launch into venture intelligence.
Our founder ran her own design studio and was the founding design partner on Partiful, on Sentropy before Discord bought it, on Goldcast before Cvent, on Make before Celonis, and on Descartes Labs. She builds here now instead of for other people.
You would own the production application around our intelligence layer. Architecture, frontend, backend, Postgres, durable execution state, retries and idempotency, permissions, deploys, and the data-heavy interfaces people work inside all day: tables, relationships, filters, history, approvals. React and TypeScript at depth, Node or Python behind it. We write a lot of MCP servers and build with Claude Code daily.
Seven-plus years shipping, hands on code within the last year. Design and engineering sit in the same room here. There is no handoff.
Most people who apply like the words "founding engineer." We are looking for someone who has already started something of their own.
Ownership. You should own a piece of what you build here. We are not going to post a percentage, because the honest answer depends on what you end up carrying, and we would rather work that out with you than hand you a number that pretends to be precise. It is a conversation, it is flexible, and we intend it to be fair.
We are six people. Nothing you build goes through a committee before it ships. Nothing you break, you fix alone. We are a tight team today and we are looking to double it by the end of the year.
Please send your resume or GitHub, plus the most ambitious thing you have built mostly on your own. Rough work that worked beats polished that never shipped.
If this is not you but a name comes to mind, please pass it along. :)

We're hiring an Onboard Technology Manager to own everything that keeps passengers connected and crew productive on the train: Wi-Fi and network infrastructure, onboard units, and mobile devices for train staff. As satellite constellations and 5G redefine what's possible for high-speed mobile connectivity, you'll help set the direction for the technology being adopted on the largest non-governmental train fleet: writing specs, defining network architectures, monitoring live performance, and driving improvement projects from their conception to the finish line.
The role is highly cross-functional. You'll work with internal partners (operations, customer product, and rail engineering) and external ones, such as tech vendors (Icomera and Advantech) and train manufacturers (Siemens, Talgo).
What we're looking for:
- Bachelor's or Master's in Telecommunications, CS, Electrical Engineering, or similar
- 2+ years hands-on with network architecture, Wi-Fi systems, or Mobile Device Management (ideally in rail or a similarly complex environment)
- Strong troubleshooting skills on complex networked systems
- Comfortable leading cross-functional initiatives and communicating clearly with both engineers and non-technical stakeholders
- Fluent German and English (internally, English is preferred, but German is often mandatory when working with suppliers and regulatory bodies)
Perks: hybrid office/remote work model, up to 60 extra remote days/year from abroad (work from anywhere), 12 free FlixTrain travel vouchers/year + 12 for friends and family, mental health support, L&D budget, mentoring program.

- LLMOps that isn't hand-wavy: evals and golden datasets, prompt/agent versioning, tracing, token and cost budgets, CI/CD for agents
- Safety in a regulated enterprise: prompt injection, data exfiltration, PII handling, human-in-the-loop, audit logging
You should have
- 7–10+ years building and scaling production systems, with recent, hands-on GenAI/agentic work in production (not just demos)
- Shipped agents or LLM pipelines at scale
- Solid data chops — vector stores, chunking, hybrid search, knowing when retrieval is the wrong answer
- Cloud experience (we're primarily AWS / Bedrock); comfortable with both containers and serverless
- Track record of technical leadership and mentoring without needing a manager title
Nice to have: LangGraph / Semantic Kernel / PydanticAI, GraphRAG, knowledge graphs, LangFuse/LangSmith, multimodal.

Better Stack | https://betterstack.com/ | /^Full-?stack Engineer$/i | Remote (North America & Europe)
We are software builders at :heart: CEO is a software engineer, COO is a software engineer, and you guessed it, CTO is an engineer, too. We are engineers, making the tools we always wanted. If you love building amazing software, you're at the right address.
We are looking for software engineers who, given enough time, could build Better Stack on their own = looking for full-stack product engineer generalists to help us create high-quality software with exceptional UX, end-to-end.
Apply at https://betterstack.com/careers/fullstack-engineer

Strobe Power | Site Reliability Engineer | ONSITE (SF) | https://strobepower.com
AI data centers are creating a massive new wave of electricity demand and putting even more strain on an aging grid. Strobe is building the power company that will meet that demand.
Our software turns batteries and generators at commercial and industrial buildings into distributed power plants that can buy, sell, and dispatch electricity in real time. We build the control stack for operating these assets and the trading platform that connects them to wholesale energy markets.
We’re a small, high-ownership team working on critical infrastructure. You’ll learn how the energy system actually works: what happens inside the electrical room of a large commercial building, how data centers are powered, how utilities and grid operators communicate, and how a battery gets commissioned and brought online.
This is early, technical, and very real-world. The software you build will control physical equipment, keep power plants online, and move money in regulated markets. We’re the only company actively trading distributed power in FERC-regulated wholesale markets, with multiple behind-the-meter power plants operating in NYC and expansion underway in California and along the East Coast.
I’m looking for an experienced SRE to own our infrastructure and reliability. We remotely operate millions of dollars of equipment, and it has to work. You’ll own our AWS environment, the control-room infrastructure that communicates directly with utilities and market operators, and the systems we use to deploy, observe, and operate a growing fleet. You’ll also work closely with the rest of the engineering team to establish good patterns as we ship new services and features.
You’re probably a good fit if you have deep AWS experience, have used Terraform seriously in production, write a lot of Python, and are comfortable working around Rust services. Energy experience is useful but not required (SCADA, DNP3, MQTT).
Stack: Python, TypeScript, Rust, Terraform, AWS, GraphQL/AppSync, MQTT, Grafana. We work in a monorepo designed for agent-assisted engineering workflows and are investing heavily in making engineers dramatically more effective with coding agents.

Please normalize 4DWW - Four Day Work Week
Whoever posts this monthly, please include the tag in your description. Employers need to know this is an in-demand feature we want. I for one will not be taking any non-4DWW jobs.

cloro | Founding Engineer, Data Scientist, Founding Operations, Founding Marketer | REMOTE (EU timezones) | Full-time | https://cloro.dev/careers/
cloro is one API for search and AI answers. You send a query, we return Google, Google News, ChatGPT, Perplexity, Gemini, Grok and Copilot results as structured fields: the answer, the sources it cited, and the position each result held. Teams use it to measure whether their brand shows up in AI answers, and to stop maintaining eight scrapers that break whenever a provider changes its markup overnight.
We are bootstrapped, remote across EU timezones, and small enough that every role below works directly with the founders.
Open roles:
* Founding Engineer | $80k-150k | backend and infra, heavy on large-scale collection. https://cloro.dev/careers/founding-engineer/
* Data Scientist | $60k-100k | turn our AI-search corpus into published research and track the engines as they change. https://cloro.dev/careers/data-scientist/
* Founding Operations | $50k-80k | finance, ops, marketing and product systems. An all-rounder role for someone who would rather build a system than run a task twice. https://cloro.dev/careers/founding-operations/
* Founding Marketer | $40k-70k | own SEO, content, and visibility in AI search. https://cloro.dev/careers/founding-marketer/
We work AI-native: Claude and Claude Code are in the loop daily across engineering, ops and marketing. Being genuinely good with these tools is part of the job rather than a bonus.
Starbridge | Senior AI Engineer and Senior Product Engineer | NYC or Remote | Full-time |
https://starbridge.ai/ Starbridge is building an AI platform that turns large-scale public and enterprise data into reliable sales insights. We are early, moving fast, and building from zero to one, so this role will have huge ownership and product impact.
AI Engineer: Applied AI plus strong software engineering. You will build, evaluate, and deploy LLM-driven features like deep document analysis and interactive chat, working with models from OpenAI, Anthropic, and Gemini. Expect hands-on Python, ML system design, experimentation, and production reliability. Bonus for RAG depth and frameworks like LangChain, LlamaIndex, or Hugging Face.
Product Engineer: (React/Typescript) who would work closely with product and design to build user-facing parts of the platform. You will craft performant, stable frontends that explain technical concepts to non-technical users and help us iterate fast based on customer feedback.
We're looking to build our in-person team in NYC but also open to remote!
Apply: https://starbridge.ai/careers and mention HackerNews or email recruiting@starbridge.ai with your resume.

We have a lot of customers and a lot of technical needs from those customers. That's why we're hiring a true Forward Deployed Engineer: a real engineer who wants to work shoulder-to-shoulder with customers and turn their hardest questions into working solutions.
You'll embed into our most important enterprise accounts, understand what they're actually trying to do, and build the maps, models, and data products that make Shovels indispensable to them, working alongside AI agents the way the rest of our engineering team does.

Modash helps brands find, manage, and pay creators - and helps creators earn a living.

The problems we care about:
- How do you make a 380M-profile dataset feel fast, trustworthy, and easy to explore?
- How do you turn chaotic influencer marketing workflows into product that feels obvious?
- How do you build tools that work for both small teams and brands like Stanley, Sennheiser, Birkenstock, and NordVPN??
We're 85 people, raised an €11M Series A, and ARR is doubling every year. HQ is in Tallinn, engineering is fully remote across Europe. No ticket factory. No seven layers of approval. Small teams, real ownership, hard product problems.

Cologne, Germany | UMH | Product Engineer | Full-time | 55 - 85k EUR | ONSITE (part remote)
Hi, Alex and Jeremy here from UMH.
8 years ago, Jeremy was absolutely frustrated with the status quo of data infrastructure in manufacturing. Companies paid millions per year for "shitty 90s software" and are still doing that today, when there is much better software out there for open-source. So we decided that we can do this better, first founded a System Integrator, realized most of the tasks in setting up and maintaining a data infrastructure can be standardized, and decided to found the currently VC-backed UMH, which is built on open source software and is open source itself.
What we're actually building: We build and scale a real-time data platform that runs hundreds of Benthos pipelines inside a single Docker container (UMH Core), processing millions of industrial messages that control actual production processes.
Plus a local-first user interface (Management Console) where both non-technical factory workers and power-users/developers can work together. And yes, we care about UI in enterprise/industrial software.

DAT | Frontline Engineering Manager, Senior Engineering Manager | Seattle, Portland, Denver | Hybrid 2-3 days/week | Full-time | $192k - $261k
I'm hiring for a frontline EM building the automation and trust layer for freight pricing, matching, onboarding, and settlement.Lead 1-3 teams (FTE + contractors), own delivery end-to-end, ~8 yrs exp typical. I expect everyone in my eng org (myself included!) to be technical and be able to help unblock the team, though your day-to-day wont be in the code.
Technical here means you can/will get into the code yourself and architecture reviews and maintain technical credibility with our junior to staff/principal level engineers. These are not player-coach roles, but these are frontline roles that need that technical capability.
Interesting problems: trust/fraud at marketplace scale; legacy-data-meets-modern-stack; and all kinds of problems that come with powering hundreds of thousands of load/shipment postings every day.
AI/LLM: We are leaned in, but still hold humans responsible for what they push and expect everyone to review and understand llm output before asking other humans to look at a thing.
Culture: I am deeply familiar with Google's project oxygen/aristotle and am building a culture where our teams can do great work with minimal bs.
Location: Must be local to one of our three locations (Seattle, Portland, Denver).
Primary Tech: Node/TS, React, GraphQL, Kafka/redpanda, k8s, AWS, etc

Paramark | Software Engineer (L4) | San Francisco HYBRID (3 days/wk) or REMOTE (US) | Full-time | $199K–$249K + equity
Paramark helps Marketing teams optimize spend across all of their channels and programs. There are proven scientific ways to do this, but they are poorly understood and practiced by only a tiny fraction of teams. Our product ingests data from all of our customers' marketing channels and uses it to train open-source ML models for both measurement and experimentation. This makes it possible for any marketer to use these methods.
In this domain, it's hard to figure out what to build, and it's even harder to be both accurate and simple. You'll be joining a small team -- we have four product engineers. That means owning systems end to end and having real influence over what gets built. Your typical project will start with a high level goal, and you will figure out the rest.
Founded 2023, 15 people, $8M from Greylock and others, cash-flow positive. Reasonable working hours: when the Mercury News covered the return of 996 culture, we were the counterexample. "We don't think early stage startup life requires 18-hour days, or even 12-hour days." https://www.mercurynews.com/2025/08/25/silicon-valley-startu.... 4 weeks PTO plus federal holidays, medical/dental/vision (100% of employee premiums, 50% for family).
Looking for 8+ years, full-stack. Some exposure to statistics, experimentation, or A/B testing helps.
Stack: TypeScript, React, Python, Postgres. Google Cloud, Kubernetes, FastAPI, taskiq.
Process: intro call; technical phone screen; one-day onsite in SF (travel covered for remote candidates)

Prior Labs | Berlin, Freiburg, NYC | ONSITE | Full-time | ML Infra, Research Scientist/Engineer, Backend, Full Stack
We build foundation models for tabular data. Deep learning transformed text and images but mostly skipped tables, which are still the data behind most clinical trials, financial models and scientific experiments. The reason is structural: no natural sequence, no spatial structure, no shared vocabulary across datasets, so the architectures and scaling laws behind LLMs don't transfer.
Our approach: pre-train a transformer on millions of synthetic datasets sampled from causal-structure priors. The whole dataset goes in as context, predictions come out in one forward pass. No per-dataset training, no hyperparameter tuning, seconds instead of hours. TabPFN v2 was published in Nature and set a new state of the art; TabPFN-3 scales to 10M rows. 4M+ downloads, 8k+ GitHub stars, in production from liquid biopsy to rail maintenance. Code: https://github.com/PriorLabs/TabPFN
Since July we're an independent lab inside SAP, with more than EUR 1B committed over four years. Models stay open, research stays public, same team and offices.
Roles (most can sit in any of the three offices):
- Senior ML Infrastructure Engineer: own multi-cluster GPU infra (Slurm on GCP today, multi-provider next), training performance and the tooling layer. We spend tens of millions per year on compute; you own that budget.
- Research Scientist, Foundation Model: drive the model agenda - novel architectures, scaling from 10K to 1M+ samples, multimodal and causal directions. PhD plus top-venue publications, or equivalent.
- Research Engineer, Foundation Model: same agenda from the engineering side. You design experiments, write the training and eval infra, and co-author the papers.
- ML Engineer, Cloud Platform: design and scale the backend that serves and finetunes the models. Python/FastAPI, Terraform, K8s.
- Full Stack Engineer, ML Platform: build the product end to end. TypeScript + Python, React/FastAPI/Postgres.
Also hiring: Applied Scientist, Forward Deployed ML Engineer, Research Scientist (Foundational Data Science), PhD research interns, plus GTM and ops roles.
~40 people with backgrounds from Google, DeepMind, Jane Street, Goldman, G-Research, CERN. Led by Frank Hutter, advised by Bernhard Schölkopf and Yann LeCun. Comp competitive with top AI labs.

Mattermost | Remote (US and Canada) | FT | Multiple roles
Mattermost (https://mattermost.com) is an open-core collaboration and workflow automation platform for air-gapped, on-prem and private clouds. Our customers are in defense, intelligence, security and critical infrastructure, including the USAF and NASA. Y Combinator led our Series B, their largest open source investment at the time.
Both openings are full stack on the core platform: Go backend, React/TypeScript frontend, PostgreSQL and Redis. The codebase is public (https://github.com/mattermost/mattermost), so most of what you build is too. We would rather hire people who ship and own complex software end to end than chase an exact stack match, so any systems or backend language and any frontend stack counts. What we look for in both roles: REST and WebSocket APIs with real networking fundamentals (HTTP, connection lifecycle), and relational databases including schema design and query optimization.
We use coding agents daily (Claude Code, Cursor, and others) for scaffolding, refactors, code review and test generation, and we treat that as core craft rather than a shortcut around the fundamentals. If you have a track record of shipping and owning complex software end-to-end, we want to hear from you.
*Senior Full Stack Engineer* $142,723 - $172,723 USD Architect and ship full stack features end to end, own the testing strategy for what you ship, and build internal tooling and testing infrastructure that makes the rest of the team faster. You will work without close supervision and hold the security and compliance bar our customers require. Nice to have: distributed systems and high availability architecture, regulated-environment security, open-source contributions, experience on remote-first teams.
Join our team: https://job-boards.greenhouse.io/mattermost/jobs/5379251008
*Staff Full Stack Engineer* $172,724 - $227,135 USD Set technical direction for the platform rather than for a feature area: architecture and roadmap across the stack, the standards for how the org uses coding agents, and the strategy for internal tooling and testing. You will influence direction across teams, partner with security and compliance on it, and mentor senior engineers. Nice to have: staff, principal or tech lead experience elsewhere, open-source maintainership, FedRAMP or ITAR familiarity, defense or critical infrastructure background.
Join our team: https://job-boards.greenhouse.io/mattermost/jobs/5405811008

Zepto | Senior Security Engineer (product security) | REMOTE (AUS) | https://zepto.bamboohr.com/careers/104
As a Senior Security Engineer (Product Security), you will play a significant role in keeping our product safe and secure by building on and maturing Zepto's product security practices. You will work hands-on and shoulder-to-shoulder with Engineering and Product teams, providing guidance and coaching across the software development life cycle while continuing to raise the bar on our security expectations and capability.
This is a security role at its core, but not a gatekeeping one. We are builders – we expect you to read and write production-level code, build tooling and automation, and contribute paved-road solutions that engineers actually want to use. Reporting to the Security Engineering Lead, you will work closely with them to develop and build Zepto's product security strategy and approach. You will apply a consultative and advisory approach when working with the wider Zepto team, empowering them to work confidently and to use the self-service capabilities you help establish.
We have excellent working relationships with our developers and we need to keep it that way. We are not the team of no. We are the team that helps make things better.
Zepto is moving quickly towards an AI-native way of building and operating. You will be someone who is already experimenting with AI and agentic tooling, or is genuinely keen to, and who is open to developing the skills to secure these systems as we adopt them. Within the Security team, you are the go-to person for:
Secure development practices Vulnerability management Security architecture advice
Working in a scale-up, means you get the opportunity to flex your skills in a variety of ways. We are agile and always willing to roll up our sleeves to get things done. You can, however, expect your day to day to be involved in the following:
Coach engineering teams and collaborate to ensure every step of the software development life cycle follows security best practices Design, build and maintain security tooling, automation and paved-road controls as production-quality software Conduct security assessments and architecture reviews of Zepto's applications and services Embed within project teams to ensure they are effectively considering information security risk and prioritising security controls Establish and document security architecture and practices in collaboration with the Security Engineering Lead, Product and Engineering teams Work with the Security Engineering Lead to support Zepto's adoption of AI and agentic systems, and experiment with AI tooling to improve how the Security team works Help manage application security incidents in collaboration with the rest of the Security team

Stpkr Technologies | Noida, India (Delhi NCR) | ONSITE | Multiple roles
Stpkr Technologies is hiring for the following roles to build the next generation of wearable devices.
We are currently looking for the following roles but we are also open to interviewing any candidates who feel like they will do their best work here - even if your skillset/experience doesn't fit the current defined roles. Our current team doesn't fit the conventional mold, and we don't expect our future hires will either. If you don't fit the advertised roles, just send us a mail per the same process with whatever job title would fit you the best.
Work is in person near Noida Sector 18, walking distance from Sector 18 Metro Station. We prefer in office work, and for you to be located within Delhi/NCR, Pay is competitive (9-12 LPA), and there are opportunities to earn meaningful equity down the line. We prefer current and recent undergraduates for our roles. If you are still in college we welcome you to apply nonetheless provided you can work as an intern for us in person. Super-flexible overall and all of our current team started out as interns. We are not flexible on in-office work because of operational requirements - please do not apply if you can't relocate/work from office.
Hiring across OS, software, and hardware. AI policy across all roles: you should be able to do the work without AI, and much faster with it.
Systems Engineer - Everything at the OS layer. You've rooted phones, flashed custom ROMs, broken and fixed Linux for fun. Comfortable in C/C++. GitHub with kernel-adjacent or LineageOS-type projects a plus. Stack: Android, Linux, C, C++, Java. Filter: send us something you built where you had to fight the OS or hardware.
Hardware Engineer - Bring-up/Debug/Integration - Take EVT/DVT boards and make them work. Comfortable with J-Link and IDE debugging, reading schematics and reference designs. KiCad/Altium/EasyEDA hobby work would make you ideal. PetaLinux experience or hunger to learn it. ECE undergrad fine. Filter: photo of a board you designed or debugged, plus what went wrong.
Hardware Engineer - Power/RF/Wireless - Make the power and RF paths behave on EVT/DVT boards. Hands-on with schematic capture, layout, soldering, scope/logic analyzer. Given two unknowns, you pick one and start measuring. Filter: sensor fusion work, how noise behaves across protocols, and SPI debug chops.
Founder's Office - Work closely with the founder and the rest of the team to manage the day to day and long term affairs of the company, the Man Friday of the company. Must have a decent degree of technical knowledge (we are a tech company after all) and be efficient at administrative tasks as well as management. Speed and learning ability are prized here, there will not always be a clear path to the work you have to do here, so you will have to figure some of it out on your own.
To apply, contact arnav@stpkr.in with the subject line "HN - Human" and a brief intro for further communication. Attach any documents you deem useful there. Please include the role you are applying for at the top of the email if it is one of the above mentioned, otherwise whatever role fits you best. Shortlisting will be online, interviews will be in person. We are hiring quickly, expect to hear back from us within 2-3 days of applying. If you don't, assume you will not. If you are using an AI agent to mass apply for jobs and we can tell, then you will not hear back. Use an expensive one :P (reiterating this, because we receive so much AI spam now.

Proxybase | Backend Systems Engineer (Rust) | Remote, Global | Full-Time
Hi HN, I’m the founder of Proxybase [0]. We’re building a SOCKS5 proxy network focused on transparency and ethical sourcing in the residential proxy market. A quick note for anyone who applied last month: thank you to everyone who reached out. We received far more strong applications than expected, and between running day-to-day operations and working through the backlog, we took much longer to reply than we should have. If you applied last month and haven’t heard back yet, I’m sorry for the delay. We’re actively reviewing those applications alongside this new batch.
Why Proxybase? The residential proxy industry has a rough history. Some providers rely on hidden background scrapers bundled into TV firmware or mobile apps, while others use payout systems that can hold provider funds for months.
We’re trying to build something better: Open-source clients: Our GUI [1] and CLI [2] are fully open source, so anyone can inspect and audit what runs on their device. Explicit consent: Providers knowingly opt in. No stealth bundling. Fair, fast payouts: The minimum payout is $1, sent directly to provider wallets in USD stablecoins. We do not hold funds to earn interest on them.
We’re hiring a Backend Systems Engineer with Rust experience to help build:
Asynchronous SOCKS5 routing infrastructure, Daemon and node orchestration, Automated bandwidth-allocation pipelines
Stack: Rust, Tokio, Axum, SOCKS5, Linux systemd daemons, SQLite
Location: Fully remote, async-friendly, flexible time zones Compensation: Competitive salary plus equity. USD or stablecoin payment options are available.
If you’re interested in building infrastructure for an industry that needs better standards, email jobs@proxybase.xyz with your GitHub, résumé, and a short note about what you’ve been working on recently.
I’ll also be around in the comments to answer questions and hear feedback.

Stand | San Francisco, CA | ONSITE
We're building the intelligence layer for physical risk: digital twins of individual homes, run through physics-informed AI World Models, to see exactly how a specific property will perform in a wildfire or hurricane — traditional models only guess at the neighborhood level. That precision lets us do what insurers historically couldn't: measure how much a new roof, cleared vegetation, or better siding actually cuts risk, then price coverage accordingly, turning mitigation into a real financial incentive instead of just advice.
We've scaled to ~$10B in insured assets in just two states in under a year. The interesting problems: ML surrogates that run physics simulations 1,000x+ faster without losing accuracy, structure-level digital twins built from imagery and property data at scale, and systems that reason across risk, cost, and homeowner tradeoffs — we're hiring across engineering and applied science.

The hiring market is structurally broken: 44% of resumes contain fabrications, ATS filters reject 88% of qualified candidates, and 27% of posted jobs are ghost jobs — while regulation (EU AI Act, Mobley v. Workday, FCRA suits) is forcing enterprises to rethink hiring AI. We're building the fix.
You'll own the intelligence layer: LLM-powered agentic workflows (tool use, structured outputs, multi-step orchestration), RAG/retrieval pipelines, lightweight ML for classification/ranking/entity matching, and evaluation loops for hallucination risk and output quality.
Looking for: 6+ years professional SW engineering (Python/TypeScript/APIs/DBs), hands-on experience with LLM APIs and agentic workflows, and ideally RAG/embeddings/vector DB experience beyond basic chatbots.
Stage: pre-launch, pre-seed, founding team, equity-only until seed round closes (~4-6 months), then competitive salary + refresh grants.

But also: while I didn't post this, that's not uncommon for a founding engineer. They're looking for someone to help start the company from scratch, typically with a healthy dose of equity. It's a calculated risk for the engineer, possibly worth anywhere from zero to a gazillion dollars depending on outcome.
I normally wouldn't comment, but expecting someone with that skillset and those kind of opportunities available to them to work for free for 4-6 months with the promise of actual pay "when our seed round closes" was so egregious I couldn't help myself, sorry.
That's common for founders, though. The CEO and CTO etc. are almost certainly in the same boat. They're not so much saying "come work for free" as "come join this group of us who are taking a leap from our current jobs and building something brand new, in hopes it'll pay off wildly."
It's not typical for founding engineers. It's plausible for a cofounder, with 30%-50% equity.

Hi, I applied for the junior role two months ago. I never heard anything back, but I'm also somewhat concerned my email got lost entirely because I sent emails from two separate addresses - one got an immediate automated response, the other got nothing. (The second email that received a response was just a generic inquiry checking on the first, so I'm concerned that one got tossed by the automated system as well). I'd be grateful if you could let me know if it was ever seen!
Hey, sorry about that. Send me a direct email julien at serpapi.com and I’ll investigate.
Same here, I sent an application a month ago I believe.
Same, applied multiple times since 2025, they always post the same ads.

New Lantern | https://newlantern.ai | Software engineers (backend and generalist product engineers, founding recruiter) | Full time in San Francisco, CA (ONSITE)
New Lantern is building an AI radiology resident—think Cursor for radiologists. Our application integrates the three software tools radiologists use all day [1], together with AI, to create a platform that saves radiologists toil and lets them focus on reading images and finding disease.
We are a series A startup with ~20 engineers (~40 total staff), have a number of live customers generating revenue, plenty of runway, and are backed by Benchmark, Anthropic, and other great investors. Our customers have told us they would cry if they couldn't use our product anymore.
We're hiring for backend and product engineering, as well as a founding recruiter to help us scale. You'll work directly with our founder/CEO, our staff radiologists, and our end users to build a product that radiologists rely on daily. You'll have real ownership and autonomy, and ship meaningful work frequently.
I'm Steve, New Lantern's Head of Engineering. If you're interested or want to learn more, shoot me a note at (my HN username)@newlantern.ai. I've already hired one engineer from HN this year and interviewed many more!

Search Atlas | Product Engineer (Product Manager role, not a Full-stack role) | REMOTE (anywhere, EST hours) | Full-time contractor | $23-$34 USD/hour | https://careers.searchatlas.com/jobs/599248-product-engineer...
We're ~160 people, fully remote, building an AI marketing platform. Our main product is OTTO, which runs a site's SEO on its own - it reads live search data and pushes the technical and on-page fixes itself, nobody queues them up. Around that we've got ad automation for Google and Meta, GBP management for multi-location brands, content gen, and LLM visibility tracking (whether ChatGPT and co are citing you). Autotrader, Hyundai, P&G, Vendasta are some of our customers.
Work happens in pods, 1 PM and 2-4 engineers. You own your pod's roadmap and ship it with them, no veteran PM signing off on your specs first. That's the part most PM roles won't hand you.
Looking for 3+ years PM in B2B SaaS with an actual technical background - eng or QA before PM, or a PM who's been getting into the codebase themselves. You should be able to read Python and TS, write your own SQL, find your way around an API, and not need an engineer to tell you what a stack trace says. We're Django on the back, React/Next on the front. QA is yours end to end including release sign-off, people tend to underestimate that bit. And you're already using Claude Code or similar daily, not "open to it".
Process is screen with me, a take-home that runs about 75 mins, technical round with one of our senior PMs, then a call with our Director of Product (who you'd report to). I usually come back to people within 2 business days.
Our ATS forces us to list specific countries but we hire from anywhere as long as you can do EST hours, so apply even if yours isn't on there.
Apply at the link and mention HN somewhere, in your pitch or wherever it fits. I'm João Pedro, I read all of them. joao.pedro@searchatlas.com if you need me, though the link's faster.
