Founding Engineer

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.
