Founding Engineer

About the Role

Join an early-stage AI company as its first engineering hire, working directly with the founder. You will turn a functioning product into scalable infrastructure for AI-powered service businesses, with the opportunity to grow into a CTO role as the company develops.

What You'll Do

• Build scalable agentic infrastructure to support substantial growth in users and workloads.
• Design and operate the agent runtime, including orchestration, memory, and systems for verification.
• Own engineering work end to end across backend, infrastructure, frontend, and AI agents.
• Set the architecture, technology choices, and engineering practices.
• Ship improvements regularly to customers running real businesses on the product.

What We're Looking For

• At least 2 years of production software experience, or an equivalent record of building and shipping real systems as a founder, solo builder, or exceptional early-career engineer.
• Experience building and operating LLM or AI agent systems used by real customers in production.
• Full-stack range, with the ability to take work from backend and infrastructure through to the user interface.
• Experience scaling a working product, including architecture, data models, runtime, or orchestration.
• Technical ownership in a founder, early-hire, or solo-lead role, with a track record of frequent production releases.
• Agent orchestration, memory, evaluation, verification, or multi-agent workflow experience is valuable; experience in recruiting, agencies, or service delivery is also relevant.
• Based in Europe and open to relocating to San Francisco within the first year.
