Overview
ABOUT THE ROLE
Full job description
ABOUT THE ROLE This is the first engineering hire at a pre-seed-funded AI infrastructure startup building the operating layer for AI-native service companies. The product is live and generating real revenue across two verticals, and your job is to turn a working system into agentic infrastructure that can scale to millions of users. You will own the architecture alongside the solo founder, with a clear path to a CTO seat as the team grows. WHAT YOU'LL DO
- Rebuild a working product into agentic infrastructure designed to hold real scale.
- Design and operate the agent runtime: orchestration, memory, verification, and the machinery that makes an AI workforce reliable.
- Own work end to end across backend, infrastructure, frontend, and agent systems.
- Set the technical stack, quality bar, and engineering culture from day one.
- Ship weekly to real businesses running live on the platform. WHAT WE'RE LOOKING FOR
- At least 2 years shipping production software, or an equivalent track record as a founder or solo builder. Exceptional engineers earlier in their career are explicitly welcome.
- Demonstrated experience building and running LLM or AI agent systems in production, with real users depending on them. Side projects and demos do not count.
- Full-stack range: able to move from backend and infrastructure through to the UI without waiting for a specialist.
- Ability to turn a working prototype into infrastructure that holds real load: architecture, data models, runtime, and orchestration.
- Has owned technical decisions with no engineering organisation above them, whether as a founder, early hire, or solo technical lead.
- Founder instincts and a track record of shipping things that real people depended on.
- Experience with agent orchestration, agent memory, evals, verification systems, or multi-agent workflows is a strong plus.
- Background in recruiting, agency, or service-delivery businesses is a plus, given the active verticals.
- Based in Europe and genuinely open to relocating to San Francisco within the first year. COMPENSATION & BENEFITS Salary: 80,000 to 140,000 EUR annually. Visa sponsorship and relocation support to San Francisco are provided from day one. LOCATION Fully remote within Europe to start, with planned in-person relocation to San Francisco. Visa sponsorship is available and relocation assistance is part of the offer.
