Robotics startup (STEALTH + YC S26) | Principal Mechanical + Firmware + SWE | SF Bay Area | ONSITE | $200–250k + 1–2% equity + benefits

We are a new robotics company based in Palo Alto, California, building wearable robotic devices that improve the endurance of humans on foot.

Our first product is a lightweight, bilateral hip product that reduces the physical cost of carrying heavy loads over distance, allowing personnel to move farther, carry more, and arrive at the objective less fatigued and more effective. The company is early but already operating in the field, with a direct feedback loop in the most demanding conditions imaginable.

We are backed by Y Combinator and a group of leading deep-technology investors.

We've recently moved to the Bay area to grow the team, and are hiring three lead engineers who will own product/ their domains, and have full authority with no inherited design decisions and no one between them and the problem. What you build will be worn in weeks by real users:

- Mechanical: structures, joints, actuator integration, ruggedness

- Firmware: real-time motor control, sensor fusion, embedded systems

- Software: device-to-cloud telemetry, test infrastructure, user apps

Shoot me (founder) a text (+1 857-327-3414) and I'll tell you exactly what we're building :)

BREAKFAST Studio | Senior Technical Program Manager | Brooklyn, NYC (ONSITE) | Full-time | $180k–$210k base + bonus | theartistbreakfast.com

We're BREAKFAST Studio, a kinetic-art studio at the Brooklyn Navy Yard. We build one-of-a-kind electro-mechanical sculptures, pieces with thousands of individually controlled moving parts, for museums, exhibitions, and collectors. We built The Pearl, the largest computer controlled kinetic sculpture on the planet (https://theartistbreakfast.com/works/the-pearl). Every piece is a custom machine: custom PCBs, stepper motion-control, molded parts, firmware, software, overseas manufacturing, all converging into something that has to run flawlessly for a decade.

We're hiring a Senior TPM to own delivery across all of it: fluent enough in mechanical, electrical, firmware, and industrial design to hold your own with every engineer, and good enough to keep a complex build from slipping between disciplines. You'll own each piece from prototype through tooling, production, test, and install — including deciding what "properly tested" means for a machine no one has built before.

You: 8–12 yrs shipping complex hardware (motors, electronics, firmware, overseas manufacturing), real factory/vendor experience, calm under install deadlines, and an eye for aesthetics — the tech serves the art.

On-site daily in Brooklyn. ~15% travel. Health/dental/vision, open vacation, summer Fridays.

Email lipton@breakfaststudio.com with "HN — Senior TPM" in the subject. I'm the MD and co-founder — I read every email and reply. OR, go here for more info and to apply: https://theartistbreakfast.com/jobs#senior-technical-program...

Junior | Remote | Any Time Zone

I don't think I can afford hiring someone in north america, I'm not a company, this is a small project that'll take more than a year

I'm looking for someone who understands C/C++ and would be willing to learn C++20. The codebase is small (<100k lines), and you'll be working with me to complete a project. I'll help you learn C++20 and various tools. I don't mind if you know very little, but you'll need to understand every line you write and be able to explain it to me. You'll be expect to problem solve alone.

Email me something to look at. JurassicTyler@proton.me I don't need a resume. I rather look at code you written entirely yourself. Pick a specific file you think is interesting.

I think some idea of what the project does might motivate?

I just wanted to say I love your ad, I have no experience with C++ but I like how straightforward and honest you are. Best of luck.

Sounds interesting and like it could be a fit for me, email sent from danlugo92 [at] gmail.com

Likely scam, rarely does someone have a first name of Jurassic.

There's usually a freelancer thread too you may have better luck there

MeanderX, formerly Orbio Earth, YC S23 | Senior Full-Stack Engineer | Germany, London, or Cape Town preferred | Full-time

MeanderX is building AI-powered grid intelligence for renewable energy developers.

The hard part of clean energy is not just building solar, wind, and storage. It is knowing where new energy generation can connect fastest to the grid.

We’re hiring a Senior Full-Stack Engineer to own high-leverage systems end-to-end: AI data analysis pipelines, scraping infrastructure, LLM extraction workflows, internal AI tools, and our customer-facing platform.

You should be excellent at coding, fast at shipping, self-directed, comfortable using modern AI tools, and excited to work across product, data, infrastructure, and automation.

Bonus points for experience in power engineering, renewables, grid infrastructure, geospatial data, scraping, document AI, or large-scale data pipelines.

High ownership, very little bureaucracy, and real impact on renewable energy deployment.

Trinsic | Senior Product Engineer | REMOTE (Europe) | Full-time

We're building the first Identity Acceptance Network, the "Visa for ID." Humanity is editing genes, starting space tourism, and verging on artificial general intelligence. Meanwhile, identity verification is still done by taking pictures of plastic cards.

Role - Senior Product Engineer (#5 on the team; ~20% of engineering capacity). High ownership, product-minded, backend and systems leaning. - This is not a ticket-churning role. You should want to understand the competitive landscape, listen in on customer calls, bring engineering insight to product discussions, and own features end-to-end. - You should be a Barrel: someone who can take on ambiguous work, pull together the right context, make tradeoffs explicit, and drive without needing to be told every next step. Revenue is surging, we need judgement to help shape the product. - Strong backend/platform experience; generalist enough to move up/down the stack when the product needs it. - You care deeply about user privacy and data security. We work on identity. Sloppiness here is not an option.

Stack & ways of working - .NET (C#) backend, React + TypeScript frontend, Azure Container Apps, Azure SQL/Storage, Bicep IaC, GitHub CI/CD. - Remote-first; North America (CT +/- 2) or Europe (CET +/- 1). Strong async work habits; 4 hrs/week of scheduled meetings on average; pairing/huddles when useful. - We use AI aggressively and prudently. You'll have a large token budget, but we expect strong judgment around the risks.

Comp & apply

- Salary is set by our compensation philosophy, with meaningful equity. We discuss compensation early so neither side wastes time.

- Apply: https://www.trinsic.id/careers/senior-product-engineer?utm_s...

If you're in a workable timezone and excited about identity infrastructure, I'd love to talk.

Kog (https://kog.ai) | GPU Engineer | Paris, France | REMOTE within a Europe-compatible timezone, one week per month onsite in Paris

We are hiring a GPU Engineer to work on the fastest LLM inference engine on standard datacenter GPUs.

You would own low-level kernel work in CUDA/PTX or HIP/CDNA ISA, the monokernel pipeline, profiling infrastructure inside it, scaling to the frontier MoE models that run in production, and building our own agents that optimize kernels and inference autonomously.

We generate 3,000 tokens/s per request on 8x AMD MI300X and 2,100 on 8x NVIDIA H200, at batch size 1, FP16, no speculative decoding.

At batch size 1, the decode is GEMV, so it is memory bandwidth bound, and MBU is what counts.

We rewrote the whole hot path ourselves, from the assembly on the chip up to the Transformer we designed around it, with the full decode running as a single persistent GPU kernel.

Try it at https://playground.kog.ai

Showing your code is part of the process.

If you are outside a Europe-compatible timezone, relocation to one is required.

ALBERT | REMOTE ALMOST ANYWHERE IN THE WORLD| Hiring principal and distinguished engineers to build net new products | up to ~ $750k Hiring: exceptional consumer product engineers at Albert.

We're a consumer fintech with 20M+ 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

If this is you, email us at recruiting@albert.com

Edit: we are in the process of rebuilding our career site to speak to how we hire (e.g. hunt, dont post, find the best). Just an FYI

Also, we carefully review every application. If we think there may be a fit, we'll reach out within a few business days. Either way, thank you for your interest in what we're building and for taking the time to connect with us.

Prior Labs | Berlin / Freiburg / NYC | ONSITE | Full-time | Multiple Roles | https://priorlabs.ai/

Deep learning transformed text and images but mostly skipped tables, even though they're 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. We're building the foundation-model approach for tabular data. We started with TabPFN. v2 was published in Nature and set a new state of the art on tabular benchmarks; since release we've scaled capabilities ~20x and crossed 3M+ downloads and 7.5k+ GitHub stars. The hard problems are still open: scaling to millions of rows, low-latency inference, new data modalities, and the infrastructure to run all of it in production.

Spacelift | Remote (Europe) | Full-time | Senior Software Engineer | $80k-$110k+ (can go higher)

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.

We The Flywheel | AI-Native Engineers & Operators | REMOTE (worldwide) | Contract / Part-time (10–40 hrs/wk)

We're a remote-first digital product studio building across sports media, AI, fitness, and personal branding — 500+ web properties and deeply AI-native workflows.

SmarterDx | 150-250k+ + equity + benefits | Remote (US only) | Multiple roles | https://smarterdx.com/careers

SmarterDx builds clinical AI for one of healthcare’s most broken systems: how hospitals get paid for the care they actually deliver.

Our physician-designed clinical AI platform reviews the clinical record, understands the nuance of patient care, and helps hospitals capture appropriate reimbursement across the revenue cycle. The core problem is hard: messy clinical data, complex regulations, payer rules, medical reasoning, and real financial stakes. When we get it right, hospitals recover millions in earned revenue, reduce manual review burden, and keep clinical and revenue teams focused on higher-value work.

We’ve hit serious scale while keeping the team unusually strong and technical: MD/data scientist hybrids, Stanford LLM researchers, former Google and Amazon engineers, former ASF board member, and others who are among the best in their fields. Many teammates have been here since we bootstrapped to $1M+ in contracted revenue before raising capital.

In 2025, SmarterDx became part of Smarter Technologies through a $1.1B deal with New Mountain Capital, reaching unicorn status while continuing to operate with the autonomy, urgency, and product velocity that got us here. Before that, we raised $71M from Floodgate, Transformation Capital, and Bessemer, including a $50M Series B.

We have real product-market fit: 85+ health systems, 300+ hospital sites, rapid customer growth, and 150% YoY headcount growth (currently at ~550). Now we’re scaling the platform.

ProxyBase (https://proxybase.xyz) | Rust Backend Engineers & Full-Stack Developers | Remote (Global) | Full-Time | $100k-$160k + Equity

Hey HN, we’re ProxyBase. We’re building an API-first, fully headless SOCKS5 proxy network designed specifically for autonomous AI agents, LLM tool-calling, and large-scale web scraping.

Most traditional proxy networks operate in a bit of a gray area—they buy bandwidth harvested from sneaky, hidden SDK bundles embedded inside free apps. We're doing things differently:

100% Ethical Sourcing: We pay our node operators directly. People run our open-source CLI client to share their bandwidth and earn microcredits in real-time. It’s fully transparent, consent-driven, and compensated.

Built for Swarms, Not Dashboards: AI agents and automated workflows can provision, utilize, dynamically route (via metadata in the SOCKS5 auth string), and settle proxy fees entirely programmatically using US based stable coins without ever touching a manual web dashboard.

Our Tech Stack:

Backend: Rust (Actix-web, SQLite/DashMap, WebSockets, Yamux stream multiplexing) Frontend / Desktop: React, TypeScript, Tauri (our client-side bridge app)

What we're looking for:

Backend Engineer (Rust): Help us scale our high-concurrency SOCKS5-to-WebSocket relay gateway and real-time ledger settlement engines. Full-Stack Developer (TypeScript / Tauri / Rust): Own our local proxy bridging software, client-side developer portal, and integration libraries. If you like systems-level programming (TCP/UDP, tunnel multiplexing, concurrent state) and want to work on clean, developer-first infrastructure, we'd love to chat.

Drop us a line at

jobs@proxybase.xyz with a bit about what you've built.

I am curious if I got it right, but the business of the company is providing exit nodes for AI bots/ strangers via peoples residential IP's? This is my impression from accessing the website. I was interested at first, but now I got a bit of ethical doubts about it.

Yep, everyone comes out happy here. It's a win-win-win. Unlike other proxy businesses, we always get our providers' consent before adding them to our pool.

What about the people receiving traffic that fraudulently looks like it's coming from a different location?

I think OPs mantra is "Scrape. Automate. Scale." It feels like people who consent to this "passive" income, do not understand what they consent to. The business model seems grey towards black. "Signup to be part of 3rd party bot farms exit node, you get paid, all will be good. Nothing bad happens, you consent"

I think you’re steering this conversation in a direction that isn’t really meaningful. We have security mechanism in place that prevents misuse and fraud.

Nice! I'll send it to a friend

Lunt | Databricks Eng (Solutions Architect, FDE) | Remote, US Only | Full time or full time contract | 120-140/hr (depending on exp, ~240-260 FTE)

I have ~10 opportunities for Databricks engineers as subcontractors to help large Databricks customers migrate to the platform. The Solutions Architect roles are heavily data-pipeline focused, and for the FDEs (Forward Deployed Engineers) want Databricks experience plus full stack experience to stand up Databricks apps for customers.

These opportunities vary from short to long term (though shorter term is probably ~6 months), and are full time even on contract. If that's you, drop me an email k at lunt dot co -- a PDF resume and phone number is the fastest way to proceed. Several of these need to start as soon as Aug 1. not dot com.

If you're deep in Databricks, hmu.

FusionAuth | Principal Software Engineer, Senior Java Engineer - Cloud, Account Executive | Varies between REMOTE (in USA, also in Europe but only for the account exec position) and ONSITE in Denver, CO, USA, details in each job desc | Salary ranges for the Principal Software Engineer it is 225k-270k, but the Euro positions don't have them :(

At FusionAuth, our mission is to make authentication and authorization simple and secure for every developer building web and mobile applications. We want devs to stop worrying about auth and focus on building something awesome.

There are a lot of companies in the auth space, but we feel like we have something special:

* a relatively unique deployment model (self-host on-prem, run in your cloud or let us operate it for you in ours)

* A well designed API first approach; one customer compared our APIs to petrichor

* a mature product (the code base is nine+ years old and we've found and fixed a lot of the sharp edges around core login use cases; but don't worry, there are plenty more features to add)

* a full featured free-as-in-beer version which makes the sales cycle easier; prospects often come in having prototyped an integration

Our core software is commercial. We open source much of our supporting infrastructure. Technologies and standards that you will work with: modern Java, PostgreSQL, Docker, Kubernetes, MySQL, OAuth, SAML, OIDC.

Puntt AI | SF Hybrid (M/W/F in our new office) - no visa sposorship. | Founding Forward Deployed Engineers | Founding Applied AI Engineers | Salary: $180,000 - $220,000 USD + equity, benefits and unlimited PTO

Our customers (real customers you've heard of) have thousands of packaging assets spread across dozens of markets, languages, regulations, and brand standards.

Every change needs to be reviewed before launch. Humans currently do most of that work.

We are automating it. The challenge isn't generating text. The challenge is building systems that can be wrong almost never.

We're looking for:

- Forward Deployed Engineers who enjoy sitting with customers, figuring out what's actually broken, and building solutions faster than a roadmap ever could.

- Applied AI Engineers who obsess over retrieval, evaluation, orchestration, reliability, and all the ways AI systems fail in production.

- Account Executives

Ditto | Engineering & Product | Remote (US: Atlanta, Austin, SF, Seattle) + APAC | Full-time https://jobs.ashbyhq.com/ditto

https://docs.ditto.live/home/about-ditto

I've been obsessed with CRDTs since I first saw them at Strange Loop years ago, and I still can't quite believe I now get to work on them for a living — in some of the most challenging environments there are: disconnected, degraded, contested, out where the cloud isn't. If that's your kind of problem, come build with us.

Ditto is the edge-native data platform that keeps distributed systems in sync when the network doesn't cooperate — an offline-first, CRDT-based layer syncing any device (phone, vehicle, sensor, server) over Bluetooth LE, P2P Wi-Fi, LAN, and tactical radio, with or without connectivity. Same core, commercial to defense; operationally deployed and network-agnostic. The problems are the fun kind: conflict-free replication with no server and no synchronized clock, multi-transport routing that never drops the connection, moving a coherent picture over links as thin as an HF radio shot, and human-in-the-loop robotics/autonomy where a detection may have to be physically carried by a moving node. Concept to field in days, not months.

Most roles are open to anyone authorized to work in the U.S.; Public Sector and forward-deployed roles require U.S. person status. Remote in the U.S. (hubs: Atlanta, Austin, SF, Seattle) unless noted.

Product — Senior PM: Cloud Database & Integrations; Cloud Infrastructure & Platform

Engineering — Engineering Manager, Data Sync

Public Sector (U.S. persons) — Senior SWE: Autonomy · Systems FDE · Portal (ATL/remote) · FDE (SF, on-site); SWE, Public Sector Application

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 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!

Syntropic (thesyntropic.com) | Founding CTO / GPU Systems Engineer | Remote (US) | Equity-heavy

We compress LLM KV cache. Measured: 8× at 3-bit with 0.43% quality delta (GPU-validated); 22× live end-to-end on a 5-tenant workload, GPU-verified this week (quantization × prefix dedup, decomposition always stated); 16.89× tenant density on a single V100-32GB. Validated across Mistral/Qwen/Llama with zero re-tuning. 90+ patents pending; design-partner pipeline; seed round in motion.

The gap: our throughput path is a reference implementation. First job is the fused Triton/CUDA dequant+attention kernel — turning a validated 22× memory result into production speed. Then you own the serving stack.

Process: call → NDA → paid 1–2 week trial on the real kernel → decide together. We report negative results straight; you should want to work somewhere that does.

RedLine Solutions is hiring a fully remote mid-level C#/.NET developer. We are looking at an early September start date. I'm posting this way ahead of time to try something weird: If you are an interested developer, please do NOT contact me directly. Instead, find someone who will vouch for you and have them send me your resume`. I do NOT need them to write a full-on recommendation--a simple, "Ross was a great developer and fun colleague. You should check him out" will be fine.

1. Please make sure your contact information is on your resume`!

2. We need a developer located within three hours of Pacific timezone.

No, I'm not on some kind of power trip (yet). I just got my fill of automated application spam a long time ago; the tales I could tell. This is my modestly creative attempt to circumvent the AI's. Might be good practice for SkyNet, eh?

We are not looking for a know-it-all. Instead, we desire a "wants to learn it all". We're a small company, but our System Architect / Dev Lead is seriously a unicorn. If he mentors you for a year or two, your career is golden with or without AI. Back in the day, I secretly believed I was one of the best around. Then I worked with Stephen. I've learned a ton from him, and I'm his boss.

We're a small, agile, creative and laid-back team who work hard but value work-life balance. I take great pains to make it so. If you're smart, work hard, and love writing software, ask a friend or former boss to vouch for you and have them send your resume`.

Here's a link to the official job listing:

You’ll work end-to-end: learn the domain, talk to users, design the UX, build the full-stack app, integrate LLMs/GenAI, and ship products used by customers and internal teams. Think human-in-the-loop review, decision support, workflow automation, escalation flows, and AI-native interfaces beyond chat.

This is a high-ownership, high-visibility role for an early-career builder who has already shipped real things. We’re looking for 0–3 years of experience, strong product taste, full-stack ability, hands-on AI/LLM experience, and a portfolio of apps, demos, repos, or case studies.

Bonus: React, Figma, enterprise SaaS/internal tools, workflow products, customer-facing work, or solo-shipped projects.

DoubleVerify (DV Scibids) | Sr. Data Engineer I | ONSITE/HYBRID - New York, NY (3x/week) | Full-time | $89K–$178K

DV Scibids is the AI-powered digital campaign activation arm of DoubleVerify — the market standard for digital media measurement trusted by hundreds of Fortune 500 brands. Our Data Engineering team owns the critical integrations and data flows that connect Scibids' optimization engine to the broader adtech ecosystem.

In this role you will own and build backend services and data pipelines that power product expansion — exploring external partner APIs, designing reliable ingestion and reconciliation layers, exposing internal endpoints for other DV teams, and keeping production systems observable and performant at scale.

Stack: Python, SQL, BigQuery, Cloud SQL, Cloud Datastore, Cloud Run (GCP), Prefect, Docker, CI/CD, Git. Java or Rust a plus.

Looking for: 3+ years in data engineering or backend engineering. Strong Python and SQL. Experience integrating with external APIs and operating production data systems at scale.

Tower (tower.dev) | Senior Backend / Platform Engineer | London or Berlin | HYBRID | Full-time

Tower is a Python-native serverless data platform. Data teams write plain Python, and we handle packaging, dependency resolution, scheduling, and execution across a serverless runtime built on Apache Iceberg. There's no clusters to manage, no YAML to write, no pipelines to rewrite to fit someone else's engine. If you've ever wanted your local Python script to just run in production at scale without a Databricks detour, that's the product.

We're a small, senior team split between London and Berlin. We've built a lot of tech: Custom run dispatch service, multi-region routing, storage based on Apache Iceberg, and the runtime itself, to name a few. This is deep systems work--things like scheduling, distributed execution, and performance. We're not gluing SaaS together.

Stack: Go and Rust for the platform, Python everywhere it matters, Kubernetes (EKS + Karpenter) on AWS, RDS Postgres, ElastiCache Redis, S3/Iceberg, WorkOS for auth.

Looking for:

* strong distributed-systems fundamentals

* comfort owning a system end to end

* taste for correctness under load

Bonus: data-platform, query-engine, or Iceberg experience; async Rust; Kubernetes internals.

Apply / questions: Email in bio — mention HN.

Odin | Lead Platform Engineer & Lead Software Engineer | Remote (US) | Full-time

Odin is the workforce visibility and compliance platform for critical infrastructure. We protect the world's largest construction projects, data centers, and critical assets, from groundbreak to post-turnover, unifying every layer of site security into a single command center: physical access control, workforce compliance, video monitoring, and drone surveillance. We're already on 500+ active projects with 100K+ workers on the platform, securing over $100B in construction value.

Our stack is TypeScript end to end, Node and GraphQL on the backend, React on web, React Native on mobile, Postgres and Kubernetes on GCP. We also integrate deeply with field hardware such as badge readers, kiosks, turnstiles, and cameras.

Obsidian Security | Staff Software Engineer | Philadelphia or Palo Alto | Full-time | $176k-$196k + equity + 401k | https://job-boards.greenhouse.io/obsidiansecurity/jobs/51527...

We secure the SaaS apps companies actually run on: M365, Salesforce, and hundreds more. You’d be on the Threat product team working full-stack. That means browser extension code (content/background scripts, manifest v3, message passing), backend services chewing through millions of events, and the data pipelines feeding our detection engine. One day you’re in TypeScript debugging why a content script won’t capture form submissions on some vendor’s weird SPA. The next you’re in Python fixing a Kafka consumer that’s falling behind. Sometimes you’re in Rust optimizing a hot path in the telemetry collector.

Big current focus is shadow AI, i.e. catching when employees paste sensitive data into ChatGPT, Claude, or whatever LLM showed up this week. You’d build the systems that detect it.

Looking for ~8+ yrs experience, real browser knowledge (DOM, event loop, SPA routing, CORS, not just “I used React”), prior browser extension work, strong TypeScript, comfortable in Python, willing to write Rust, plus data-at-scale chops (event streaming, Postgres, Elasticsearch, Kafka). Bonus: AI security (prompt injection, exfiltration), detection engineering/SIEM, or security tooling.

Stealth | Founding Engineer | NYC | ONSITE | Full-time | $180k-$220k base + equity

We're working in the AI for science space, specifically at the point of experimental execution. Scientific labs run on expensive instruments locked behind proprietary software with no real API. Getting an agent to actually operate these machines is unsolved, and it's the bottleneck between "AI can design experiments" and "AI can run them." That's what we're building.

Small, technical, well-funded team with real design partners already pulling on us. You'd be one of the first engineers, working directly with the founders across the stack: agents, low-level systems, ML infra, and the runtime that ties it together. Lots of hard, unglamorous, high-leverage problems.

You might be a good fit if:

- You're a strong generalist who's shipped real systems and can go deep when needed

- You're comfortable in messy, low-level territory

- Bonus: ML/agents, scientific instrumentation, or industrial automation

- You want high ownership, high pace, onsite in NYC

We're mostly a Python/Rust/Typescript shop. We care about what you've built, not credentials.

To apply, email contact@tetherline.dev with a bit about yourself and something you've built you're proud of.

Kanary | Full Stack Engineer | Remote (US) | Competitive Salary + Equity + Benefits | Python / React

Kanary is a personal security platform that monitors the web to identify and reduce risk based on an individual's threat model.

We've been building since 2020, started in campaign security and data science, backed by Mozilla and Y Combinator. We have 200+ organizations on the platform and are funded by our customers.

Attackers have never had better tools. LLMs, social media, and search surface personal data in new ways. A few prompts can launch a deepfake and impersonation campaign. Risk sources appear and disappear across social platforms, telegram chats, and private data broker platforms. Kanary exists to play the cat and mouse game for people at the speed and scale of an agentic internet.

Kanary is a combination of software workflows (crawling, scraping, automation), AI (data classification, research, code generation), and people (analysts trained to support customers and escalate). This is an exciting opportunity for those who are interested in building systems and agents to solve hard and often adversarial problems.

We’re growing our team, and seeking a multifaceted engineer (2+ years experience). We’re looking for engineers with web scraping, data pipelines, or security tooling experience. Experience with Python/Django, Typescript, React, and LLM APIs is a plus. Must be authorized to work in the US.

Email steven@kanary.com with something you've built and why it was hard. Also be sure to include the keyword I’ve put in my HN profile.

Ro (ro.co) | direct-to-patient telehealth | NYC (hybrid, 2x a week in office)

Lots of open eng roles :) but we want to specifically highlight a brand new one for us: - Senior AI Engineer: https://jobs.lever.co/ro/81dd41da-ba24-435b-83c4-bd19a312744...

This is on a new team we’re building from the ground up. We've got an awesome Engineering Manager you'll work alongside, and you'll own AI features from prototype through production and spend as much time improving workflows with clinical operators as writing code.

Most of your work will involve building orchestration layers, prompts, evaluations, retrieval systems, and tooling that make LLMs reliable enough for real-world healthcare operations.

Relevant Healthcare | Software Engineers (multiple levels) | Remote (US/Canada) | Full-time

Relevant builds a data platform that helps safety-net healthcare providers deliver better care using data from their electronic health records. Our customers are non-profit clinics called Community Health Centers. You can read more about them, us, and the roles on our jobs page: https://relevant.healthcare/jobs/

We're a small team (~25 overall). We're bootstrapped (no external capital whatsoever, VC or otherwise) and profitable. We've got a modern tech stack (Rails, Typescript, React, GraphQL, d3) and a healthy approach to both tech debt and work/life balance… and we’re also a very nice group of people that get to work on interesting problems for some of the few unimpeachably good actors in healthcare!

Rivio.ai | Senior / Staff Software Engineer | SF, hybrid/remote (US only) | $200-$250k + equity | Apply: https://www.rivio.ai/careers/senior-software-engineer-ai

Rivio embeds procurement intelligence directly into sourcing and negotiation workflows — helping teams capture savings and build institutional knowledge without adding headcount.

Backed by Google, MIT, S32. Customers include Checkr, Cribl, Brex, Harvey, Oura.

What Makes This Role Different:

- Building across AI agents, knowledge graphs, and integrations as a full-stack generalist, wherever the hardest problem lives

- Real product with real customers, not internal tooling

- Everyone at the company is an AI power user, and we’re pushing the boundaries of native AI engineering

- High ownership, no bureaucracy, outsized equity at an early stage

- We think the best engineers today have the judgment needed to direct their army of agents, and do the work themselves when needed.

Reach out directly with any questions: llarrere@rivio.ai

3Play Media | Principal Front-End Engineer (Growth) | Boston, MA | 1-day-in-office hybrid or fully remote (USA only) | Full-time | 3playmedia.com | $200–250k + bonus + equity

3Play makes content accessible across disability and language. Our human-QA'd captioning, audio description, subtitling, and dubbing services are used by over 10,000 media, higher ed, creator, enterprise, and government customers. We’ve worked on really cool projects: recent examples including captioning the 2024 Paris Olympics and providing quality AI dubbing for high-profile YouTube creators.

I'm leading the Growth team, and we're working to build new, beautiful UI experiences on our long-loved services. Our stack is a Remix/Rails product and Astro/Sanity marketing site, both backed with modern design system foundation (what you might expect with Typescript, Tailwind, ShadCN, Tanstack, etc). I'm looking for a principal-level engineer with strong taste in front-end: someone who cares about UX and styling, takes accessibility and page weight seriously, builds strong validation / testing harnesses, and keeps a dependency tree sane instead of letting it metastasize.

The other part of this role is contributing to our agents and workflows. We've invested heavily here with the right mix of enthusiasm, guardrails, and budget. You'll have heavy influence over how it evolves: what we hand to agents vs. keep in human hands, how work gets specified and parallelized, how we keep the results beautiful, and where the security and review gates live. There’s a ton of opportunity to work with the latest AI tooling and determine best practices as the industry matures. We’re a small team happily working over 15 years with high impact, high autonomy, and low bureaucracy. Come join us! Apply at https://www.3playmedia.com/company/jobs-post/?gh_jid=7761973.... Mention HN when you apply!
