About the Role

Join an early-stage AI infrastructure startup as its first engineer. You will work directly with the founder to evolve a functioning product into scalable infrastructure for AI-powered service businesses, with broad ownership across the product and its technical direction.

What You'll Do

• Develop the architecture and infrastructure needed to scale the product to a large user base.

• Build and operate the agent runtime, including orchestration, memory, verification, and supporting systems.

• Take projects end to end across backend, infrastructure, frontend, and AI agents.

• Set technical standards and guide how the engineering team builds as it grows.

• Ship improvements regularly to users operating real businesses.

What We're Looking For

• At least 2 years of experience shipping production software, or an equivalent record as a founder, solo builder, or exceptional early-career engineer.

• Experience building and running LLM or AI agent systems in production, with real users relying on them.

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

• Experience turning prototypes into dependable systems through sound architecture, data models, runtime design, and orchestration.

• Evidence of owning technical decisions and delivering quickly in an early-stage or independent environment.

• Strong generalist engineering skills and practical experience with agent workflows, memory, evaluations, or verification are valuable.

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