Software Engineer, Foundation

ABOUT THE ROLE This is a foundation engineering role on the mobile platform team at a Series B EdTech company, where your work sits beneath everything product engineers build and ships to millions of students worldwide. You will own core infrastructure across a Flutter mobile app, agentic and AI tooling, and developer experience, multiplying the output of 25+ engineers every day. WHAT YOU'LL DO - Own shared components, the design system, state management, performance, and tooling within the Flutter mobile app. - Build and maintain agentic and AI infrastructure, including custom MCP servers, a background agent platform, and evaluation and feedback loops. - Integrate agentic coding tooling into day-to-day engineering workflows across the team. - Improve developer experience through CI/CD pipelines, release tooling, and faster feedback loops between writing code and seeing it live. - Ship user-facing product features alongside platform and infrastructure work. - Keep the existing foundation reliable so a growing team of engineers can build on it with confidence. WHAT WE'RE LOOKING FOR - 2 to 4 years of production experience building mobile apps with Flutter and Dart, or equivalent web application experience. - Daily, fluent use of agentic coding tools (such as Claude Code, Codex, or similar), with a genuine point of view on where they excel and where they fall short. - An eye for design: you notice inconsistent spacing, animations that feel slightly off, and components that are close but not quite right. - Strong academic background in Computer Science or a related field from a well-regarded university. - Clear written and spoken communication in English, and a genuine drive to improve systems that slow other people down, even when the work is not directly visible. COMPENSATION & BENEFITS Salary range: 80,000 to 110,000 EUR annually. Visa sponsorship is not available for this role. LOCATION On-site in Berlin, Germany.
