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 .
