I'm Daniel, co-founder. Lumen Labs is building the cognitive layer for physical AI. Nearly every major robotics effort today teaches machines by showing them thousands of hours of human teleoperation. We think that paradigm has a ceiling, and we're working on nature-inspired architectures for unstructured environments (construction sites, mining, pipelines, battlefield). Pre-seed, backed by top VC funds and operators from robotics/AI companies.
We're a team of two and hiring teammate #3 to own the hardware and infrastructure that keeps our research platforms running: the ROS2 (Humble) stack across onboard and offboard compute, sensor integration and calibration (LiDAR, depth, IMU, encoders), the safety pipeline during autonomous runs, and getting trained policies onto real hardware. Today that's wheeled navigation; we're dipping our toes into drones and eyeing weirder platforms like pipeline inspection. Where we're at: zero-shot sim2real transfer with a policy that runs at 100Hz on an ESP32 and took under a day to train.
You: hands-on with real mobile robots (UART, encoders, PWM, IMU, LiDAR), strong Python + embedded, comfortable reading code you didn't write, and can debug hardware and firmware at the same time. If "full-stack" to you means firmware, a multimeter, and a ROS node in the same afternoon, you'll fit right in. Visa/relocation support for the right person.
Full posting: https://desert-bearskin-26d.notion.site/Robotics-Engineer-Ro...
Email hi@lumenresearch.co, mention HN, and tell us about a project you've built. If you can link to a time you got a trained policy running on real hardware, you go to the top of the pile.
A hedge fund analyst covering therapeutics has to watch hundreds of companies at once: press releases, SEC filings, management calls, updates on government sites, clinical data publications. Obi9 ingests all of it and surface what matters. Hedge funds pay for it today.
We are early and the team is small, so you would own entire surfaces of the product rather than pick up tickets:
- Ship full-stack features end to end, from the data model to the interface.
- Build the ingestion and enrichment pipelines that turn raw data into rich insights and alerts.
- Work on AI-backed features, from ideation to serving them in the webapp and over MCP.
- Make heavy data legible: dense tables, financial charts, document viewers, a live alert stream.
Stack: React + TypeScript, Node, Elixir, Python, distributed AI pipelines.
Beyond full-stack ability we want someone who already understands one of these worlds. One is enough, we are not asking for all four:
- Financial information systems. Bloomberg, FactSet, AlphaSense, Capital IQ, PitchBook. You know what entity resolution, identifier mapping and point-in-time data cost to get right.
- Financial domain knowledge in healthcare. Equity research, valuation, or time spent living inside filings and models.
- Audio and transcription. OtterAI Deepgram, AssemblyAI, Whisper. Diarization, speaker attribution, turning messy call audio into something quotable.
- AI-intensive products where the pipeline IS the product. Legal AI, document intelligence, medical coding. You know what evals, grounding and extraction schemas that hold actually cost.
Minimum: 5+ years building production web applications, a technical degree, fluency with current AI tooling, and eight continuous hours inside the 8:30am to 5:00pm ET window.

We're a consumer fintech with 25M+ users who trust us to budget, save, invest, and bank in one place. Profitable for 4+ years. And as of today, our average employee tenure is 3.6 years, a number you almost never see in startup tech, and one we're quietly proud of. People stay because the work is good, the people are sharp, and we've built something worth staying for.
Now we're building net-new consumer products from zero, and we're looking for people who love to tinker and build stuff to ship them with us.
The kind of person we're looking for: • Top fraction of a percentile in craft, the kind of good that's hard to fake • Builds for fun, not just for work. The kind who ships a working prototype over the weekend and can't help themselves • Comfortable owning 0 to 1 consumer products end-to-end • Allergic to politics, theater, and bureaucracy
What you get: • Remote, anywhere with reasonable timezone overlap (and for someone truly exceptional, we'll make async work) • Real scale from day one (20M+ users, real money, real consequences) • Compensation that beats the market. We pay well and we mean it. Base, discretionary year-end bonus, meaningful 401(k) match, and meaningful equity in a profitable, growing unicorn (the kind that's actually worth something) • Platinum PPO health benefits with Blue Shield, top of the top of the line, covering your entire family • A mission worth your time: make money simple, so people spend less time managing it and keep more of it • Small senior-heavy teams, direct ownership, no layers • Forthcoming with the business metrics that matter, so you always know how the company is actually doing • The startup perks done right: catered lunches, wellness stipend, team offsites, casual dress. The stuff that compounds when you're showing up engaged for years, not months • Profitable for 4+ years, so you build with conviction, not runway anxiety
Stack: python, claude, postgres, react.js /react native

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.

Happy to share more details with qualified candidates. Thanks for reading.
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 your emails. joao.pedro@searchatlas.com if you need me, though the link's faster.
P.S: If you're not a PM, you can still reach out, explain your role briefly and I can redirect you to an appropriate role, or you could just check out our careers page and apply directly to the role that suits you best (preferred method).
We are a people-first, boutique tech agency creating on-demand teams and software solutions for long-standing clients. These clients trust us to practice engineering excellence as though we were members of their own staff. Our leadership team is ex-Fortune 100 with software engineering backgrounds: we’re still coding. Notable recent projects include a gigantic ERP migration for Anduril, and working with Surge Labs to help develop some of the frontier LLM models from the big guys themselves (yes, seriously). This is a remote-first agency, but some projects involve onsite work.
I’m the founder and CEO, and I’m trying to do what I call “enlightened business”. I take responsibility for both staff and clients, and I look for people who approach their work with a similar sense of ownership.
For September 2026: our current work would especially benefit from from ai-forward senior engineering expertise that can design RL benchmarks, red-team model outputs, and create rubrics to evaluate and enhance the agentic coding capabilities of various frontier models. We received 216 applications in our August posting, and issued offers to approximately 10 (still following up with a few).
Applicants must meet a high bar - I intend to have a personal relationship with every hire. In return you’ll get:
* 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 Feel free to submit, even if you already did in the past.Current roles available:
Back-end, Front-end, and Full-Stack Software Engineers, Tiers 3 and 4 (Typescript/Javascript, React, NextJS; Ruby on Rails; Python; DevOps, and third-party API integrations)
Tier 3 roles are typically 5-10 years experience with $140-$180K total comp. Tier 4 roles are 11-20 years experience, $210-$264K total comp. Higher tiers exist, and we always welcome exceptional applications.

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 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.

Questions welcome in the replies here.
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.

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.

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.
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.

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
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.

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.

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. :)

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.
When you look at the headers of major websites, you’ll see us. If it has to be performant, secure, scaled worldwide, and always-on, it uses Fastly.
We're a global edge cloud platform for performance and security, emphasizing open standards, sustainable engineering, and resilience-by-design.
We're hiring across compute, security, platform engineering, network and edge protocols, release engineering, network architecture, client services engineering, and more.
Onsite preferred, but remote candidates with a strong fit are welcome!
Rather than building walled gardens, we co-founded the Bytecode Alliance, heavily upstream our work to open standards, actively author IETF drafts, and power the global infrastructure for open-source Python, Rust, Ruby, OpenStreetMap, and much more.
* The Stack: Rust, C/C++, Go, Javascript, Typescript, WebAssembly (Wasm/WASI), Wasmtime, Cranelift, eBPF/XDP, QUIC, HTTP, TLS, TCP, Varnish/VCL, Linux kernel internals, distributed systems, professional services. * Apply: https://www.fastly.com/about/careers
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.
