• Who We're Looking ForStrong Software Engineering / AI Engineering background.
• Hands-on experience building production applications with modern AI technologies.
• Strong knowledge of Python and backend engineering.
• Experience with LLMs, RAG, AI Agents or Agentic workflows.
• Strong understanding of software architecture and system design.
• Comfortable owning problems end-to-end rather than working within a narrow engineering remit.
• Previous startup experience is highly desirable.
• Founding Engineer, early employee or entrepreneurial experience would be particularly attractive.
• Evidence of building and shipping products quickly.
• High level of ownership, autonomy and commercial awareness.
• Comfortable working directly with founders in a fast-moving environment.
• Genuine interest in AI beyond simply integrating third-party APIs.
• Fluent German and English.
• Willingness to work predominantly on-site in Berlin, ideally 5 days per week.

• Why Join?Join as one of the founding engineers, not employee #200.
• Meaningful equity participation and long-term upside.
• Direct influence over the product, architecture and technical roadmap.
• Work side-by-side with the founders.
• Build an AI-native product from its earliest stages.
• Significant autonomy and technical ownership.
• Opportunity to shape the engineering culture and future team.
• Work in-person with a highly ambitious team in Berlin.

This is particularly suited to engineers who have already experienced startup or founding environments and want their next role to give them considerably more ownership, influence and upside.
