Founding Engineer (Europe to San Francisco)

About the Role This is a founding engineering role at an early-stage AI infrastructure startup building the operating layer for AI-native service businesses: an agentic workforce, a company knowledge layer, a human trust layer, and a unified cockpit to run operations. You will join as a founding team member, shaping the platform from scratch with no legacy code and no pre-written roadmap. The role carries real ownership and real accountability from day one. What You'll Do Build the full platform end to end, making architectural and product decisions yourself. Talk directly to users, define the right outcomes, and ship to production, without waiting on a ticket. Iterate rapidly on agentic AI systems, tooling, and core infrastructure in a very small, high-trust team. Own what breaks, diagnose it, and fix it, then raise the bar so it does not break the same way again. What We're Looking For A proven builder who has shipped something real to real users and can speak honestly about what broke and how they fixed it. A product-engineer mindset: you define the outcome, not just the implementation. AI-native: you use AI tooling to write and ship code at a pace that would have looked unreasonable a couple of years ago. Intensity and drive, ideally with experience founding something or joining a startup at an early stage. Firm commitment to relocating to San Francisco by January 2027, this is a firm requirement, not exploratory. Compensation & Benefits Competitive salary while based in Europe, switching to a San Francisco-equivalent salary on the day you arrive. Meaningful early equity. Visa sponsorship is fully covered, as is the cost of relocation. Location On-site. Currently based in Europe, with relocation to San Francisco required by January 2027. The company operates in person in both locations. Visa sponsorship is available.
