Software Engineer, Foundation

ABOUT THE ROLE Join the foundation engineering team at a Series B education technology company building an AI-powered learning platform. You will strengthen shared mobile, AI, and developer infrastructure while also contributing to product software used by students. WHAT YOU'LL DO - Own and improve core parts of a Flutter mobile app, including shared components, design systems, state management, performance, and tooling. - Build and support agentic and AI infrastructure, including MCP servers, background agent platforms, evaluations, and feedback loops. - Integrate agentic coding tools into engineering workflows and improve CI/CD, release tooling, and developer feedback cycles. - Ship user-facing product features alongside platform work. - Keep shared systems reliable so product engineers can build on them with confidence. WHAT WE'RE LOOKING FOR - Two to four years of production experience building mobile or web applications, with professional backend engineering experience. - Hands-on experience shipping product or backend software in production; research-only work is not a substitute. - Flutter and Dart experience is a plus, but strong web application experience is also relevant. Deep platform engineering or architecture tenure is not required. - Daily, fluent use of agentic coding tools such as Claude Code, Codex, or similar, with a considered perspective on their strengths and limitations. - A strong academic background, entrepreneurial experience such as startup or founding-engineer work, and clear English communication. - Good design judgment and an interest in improving systems that help other engineers work effectively. COMPENSATION & BENEFITS Base salary: €80,000 to €110,000 annually. Visa sponsorship is not available. LOCATION On-site in Berlin, Germany.
