The role

You’ll own the core intelligence of their agents: how they plan, reason, use tools, check their own work and get better over time. This is systems engineering, not prompt engineering.

• Build the systems that let agents test, verify and improve their own output

• Connect agents to browsers, development environments and internal tools


• Improve orchestration across generation, validation, deployment and monitoring, at real production scale

What they’re looking for

• You’ve built agent harnesses or multi-step agent systems in production and owned the core architecture


• Strong engineering fundamentals and a track record of shipping reliable production systems


• You know how to build dependable systems around non-deterministic model behaviour


• Strong full-stack skills (TypeScript, React, Python) and sound product judgement


• Experience with automated testing, evals and parallel execution

Nice to have

• Multi-agent systems


• Code generation products


• Browser agents, computer use or developer tooling


• Previous founder or founding engineer experience


• Competitive programming or open-source contributions

Package

• $250,000 to $300,000 base plus equity


• On-site five days a week in the San Francisco Bay Area


• Relocation support available. TN, H-1B transfer and F-1 OPT welcome (no new H-1B sponsorship)


• Unlimited PTO, 401k match, full medical, dental and vision, and meals in the office

Salary: USD 250000-300000 per year
