ABOUT THE ROLE

Join an early-stage AI company as its first engineering hire, partnering with the founder to turn a working product into reliable infrastructure for AI-powered service businesses. You will help shape the architecture, agent runtime, and engineering practices as the product scales.

WHAT YOU'LL DO

- Rebuild the existing product into infrastructure designed to support significant growth.

- Design and operate agent systems, including orchestration, memory, and verification.

- Own projects end to end across backend, infrastructure, frontend, and AI agents.

- Set technical direction, choose the stack, and establish a high-quality engineering culture.

- Ship improvements weekly or faster to customers using the product in their businesses.

WHAT WE'RE LOOKING FOR

- At least two years shipping production software, or an equivalent record as a founder, solo builder, or exceptional early-career engineer.

- Full-stack range, with the ability to work across backend, infrastructure, and user interfaces.

- Experience building and operating production LLM or AI agent systems relied on by real users.

- Experience evolving a working prototype into scalable infrastructure, including architecture, data models, runtime, and orchestration.

- Evidence of owning technical decisions in an early-stage environment, and the ability to explain the difficult parts of systems you have shipped.

- Experience with agent orchestration, memory, evaluations, verification, or multi-agent workflows is useful.

- Founder experience or familiarity with recruiting, agencies, or other service-delivery businesses is a plus.

- Based in Europe and willing to relocate to San Francisco within the first year.

COMPENSATION & BENEFITS

Base salary: €80,000 to €140,000 annually. Equity is part of the founding-level opportunity. Visa sponsorship and relocation support are available for a move to San Francisco.

LOCATION

Remote within Europe, with an expectation to relocate to San Francisco within the first year.
