Mozilla | Sr. Staff Software Engineer, Browser (New Products) | REMOTE (US or Canada) | Full-time
Mozilla's New Products group is a small team building new things on top of browser engine technology. We're hiring a hands-on, senior IC to run experiments inside browser engine internals and find out which ideas actually hold up.
What you'd do: design and build experiments in engine subsystems (DOM, layout, accessibility, JS runtime, networking), prototype features that let programs interact with web pages reliably, and measure everything. That means repeatable benchmarks, profiling overhead, and writing up the experiments that didn't work too. You'll use AI tools heavily, but you'll verify what they produce by testing and measuring it.
You likely have: deep experience in at least one browser subsystem, strong C++ or Rust, comfort in a very large codebase, a solid grasp of how the web platform behaves, and a real interest in AI agents and their tooling. Contributions to Gecko, Servo, Blink or WebKit are a big plus.

Sidekick Labs | Senior Technical Product Manager | REMOTE (US Timezones) | Full-time | $170k to $230k Base + Equity + Health
Sidekick builds AI security software for enterprises. Our sensors observe AI behavior and use in situ. From those observations, our reasoning pipeline produces an application inventory and a risk picture, allowing us to provide real-time intervention and coaching right when it matters.
Compensation: base salary scaled to experience, meaningful early-stage equity, and 100% covered health insurance for you and your immediate family.
We are a highly senior team. Most of us have been founders or on early founding teams, so we operate with high ownership. The PM team is small, and everyone on it has a real, current AI-assisted practice: we design, prototype, and build with AI tools every day.
The role: You'll spend your time with customers and in the product. You'll run discovery with CISOs and IT teams, guide pilots, and turn what you learn into clear direction for engineering. You'll also build: design and prototype with AI tools, make your own tools for research, analysis, and reporting, and open PRs against the product when that's the fastest way to get something done. On a small team, expect to take on whatever the company needs.
What we're looking for:
- 10+ years building B2B software, at least 5 of them as a PM
- Customer discovery and pilots you ran yourself, ideally with enterprise IT or security teams
- Things you built yourself that you can walk us through: prototypes, internal tools, or merged PRs
- Crisp, clear communication, written and spoken, with customers, engineers, and executives
- Security experience is a plus
To apply: Send an email to hiring@sidekicklabs.com with "Senior Technical Product Manager" in the subject. Include a PDF of your resume, links to your LinkedIn and any GitHub or personal site, and a short description of something you built yourself (a prototype, a tool, a PR): what it does and why you built it. Include a link if you can share one.
I'm Paul, VP of Product: https://www.linkedin.com/in/paul-riegle/

Helmsted | Founding AI Engineer | REMOTE (US) | Full-time | $160K–$200K + equity | https://helmsted.ai/careers
Helmsted is the AI-native operating system for wealth advisors of complex households: planning, tax and estate analysis, meetings and the client portal, run by agents that do the work. Small team, live with pilot firms, shipping daily.
You'd build the agents and the intelligence behind them with our CTO: evals and systems that improve from their own usage, long-term memory, retrieval over millions of documents, model routing and cost, and secure, permissioned access to client data. Fintech experience is a plus, not a requirement.
Remote in the US today, with eventual relocation as the team centralizes. Paid sick leave; health insurance and 401(k) under discussion. Applications accepted on an ongoing basis.
To apply, email careers@helmsted.ai with a resume and short answers to the questions in the full JD: https://helmsted.ai/careers/helmsted-founding-ai-engineer.pd...
AI x Healthcare Startup | bracehealth.com | Boston, MA Onsite | Full-time | Early Engineer
We're looking for a backend-leaning fullstack dev. You will be one of the first engineers outside of the founding team. Here is a bit more about us: We're a seed stage AI startup backed by top tier investors. We're on a mission to ensure every patient gets covered for the care they need and every doctor gets paid for the work they do.
We’re building deep, vertically integrated technology systems to solve fundamental problems in US healthcare - the biggest market in the world ($5T). We use AWS, K8s, React, and Rust but there is no requirement to have prior experience with them specifically. We'll teach you!
We are a founding team made up of ex-YC, Amazon, Meta, Microsoft, and Harvard Business School with previous successful exits.
You’ll own entire product areas and be expected to play a true full-stack role, with the ability to go from customer need to end-state product. You’ll work directly with the CTO at the edge of what's possible with LLMs and agentic systems applied to a hard domain. You'll contribute to technical strategy, make real architectural decisions, and write vast amounts of production code with AI first developer workflows. Most importantly, the technology you build will have real impact on real people - clinics staying open, clinicians getting paid, patients getting care.
This is an opportunity to work in a fast paced, high ownership environment while solving real problems in healthcare.
We're happy to share more details on the role in person/on zoom. Please fill out this form if interested!
Mesmer (YC P25) | Founding Engineer | Berlin | ONSITE | VISA + relocation | €100–140k + 0.5–1% equity
Mesmer builds software factories for engineering teams. Keeping a team at the state of the art with agents is a full-time job, so we do it for our customers: we're always finding the biggest bottleneck in how their team ships and fixing it in their factory.
As a founding engineer you'd do both halves. You'd work in customers' factories, at the frontier of how software gets built with agents, and you'd build the product that makes that work repeatable. We're seven people, repeat founders and CTOs, in one office in Berlin.
We're looking for senior engineers who use coding agents every day and have strong opinions about how the work around them should change.
About two weeks from first call to offer, no live coding or take-home. Email hiring@mesmer.co with a short intro and something you've built.
Thunder Compute (YC S24) | C++ Systems Engineer | San Francisco (Onsite) | Full-time | Visa sponsorship | https://www.thundercompute.com
We run a GPU cloud on systems software we built from scratch in C++. We're hiring for our systems engineering team; designing the distributed system behind what is essentially a hypervisor for GPUs.
You'd report to Brian, our CTO (ex-Citadel Securities quant dev). Team is from Citadel Securities, Aquatic, Old Mission and AWS. Series A, $17.5M+ from Matrix and YC.
Comp: $250–325K base, 0.1–0.3% equity, highly competitive profit-sharing bonus pool. Currently there are $3.3M in bonuses entering this pool tied to gross-profit milestones.
Apply: https://jobs.ashbyhq.com/thundercompute/2efae53b-817c-43e7-9...
If you're cracked at systems software and want to do something more meaningful than creating liquidity, reach out.

Voluntas | Remote | Full Time | Software Engineer
Voluntas is a trading firm written 100% in Rust. We run systematic strategies, currently specializing in prediction markets, looking to expand our systems more broadly.
We're looking for someone passionate about data collection, clean abstractions, and processing trillions of rows of data. We are about the quality of the code we write, and we prioritize time for our engineers to properly build their systems, instead of pressuring them to churn out AI generated code.
If you're interested, send an email to jobs@voluntas.io with a little bit about yourself. We'll respond with a link to our engineering challenge (in Rust).
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, ~16 people, $8M from Greylock, 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)

I’m Shay, a founding engineer at Opsin. We build security software that helps enterprises understand which AI agents they have, what those agents can access, and where they pose a risk. We recently raised funding (https://www.opsinsecurity.com/blog/opsin-raises-21m-to-expan...) and are growing our engineering team.
We’re hiring across three roles, from 3+ years of experience through Staff level: - Product Engineer: Build customer-facing features end to end, from understanding the problem to shipping and iterating. https://www.opsinsecurity.com/jobs/product-engineer - Backend Engineer: Build and operate APIs, services, and data workflows behind our security platform. https://www.opsinsecurity.com/jobs/backend-engineer - AI Engineer: Build production AI systems that evaluate agents and turn identity, permissions, data, and activity into explainable risk insights. https://www.opsinsecurity.com/jobs/ai-engineer
Location: San Francisco / San Jose preferred; Boston and NYC areas also welcome. Hybrid means 2–3 days together in person each week. Fully remote within the US is also possible for the right person.
Compensation: $175K–$250K annual base, depending on level and qualifications, plus meaningful early-stage equity and comprehensive benefits through Justworks. Visa sponsorship available.

Stratirus (a Tennetech company) | AI Developer + Linux Admin (junior to mid) | REMOTE (US only, Central Time hours) | US work authorization required, no sponsorship | Full-time or part-time, contract or hire | $65k to $100k | No agencies
Our optional take-home is a broken Ubuntu server: a service that won't stay up, a nightly report that hasn't gone out in days, and a disk that keeps filling. Fix it, write a script that heals a fresh box, and build a small read-only MCP tool so an AI agent can check on it. 60 to 90 minutes, unpaid, no LeetCode. If that sounds like fun, read on.
We're a small and growing AI and Microsoft 365 consultancy in Franklin, TN. We build AI agents and automation for small and mid-sized businesses, and harden and run the systems underneath: Microsoft 365 tenants, SharePoint, and Linux boxes. We're AI-agnostic and use what fits the client, mostly Claude Code, the Microsoft 365 stack with Copilot and Copilot Studio, Gemini and Gemini Studio, and Oracle OBI. The role is about 60% agent development (MCP servers, Claude Code, Copilot Studio, Power Automate, Gemini) and 40% Ubuntu administration (systemd, Docker, patching, backups, monitoring). PeopleSoft experience is a plus. You'll work directly with clients, so explaining things clearly to a small-business owner matters as much as the code. Early-career and career-switchers welcome.
We expect you to use AI every day. What we hire for is knowing when it's wrong, so one of our three application questions asks about a time it fooled you.
To apply, email your resume to hiring@stratirus.com with short answers to: a time a client or boss made an unreasonable demand and how you handled it; a time an AI confidently gave you a wrong answer you followed, and how you caught it; and something you've built with AI that you still use. Work samples get strong preference. We read every application ourselves and reply to everyone, so please write your answers yourself.
Process: email application, a 45-minute video call where you walk us through something you've built, then a conversation about the role.
Remote within the US only, Central Time business hours. Must be legally authorized to work in the US without visa sponsorship, now or in the future. No recruiters or agencies, please.
