Flutter Developer

You build the app 40,000 professional car dealers open to buy, price and move vehicles, in a team where coding agents write the first draft and your judgement decides what survives review. You own mobile features end to end: design, build and maintain scalable Flutter and Dart applications, from concept to production.

What you'll do

• Own mobile features end to end: design, build and maintain scalable Flutter and Dart applications, from concept to production
• Build AI-first: coding agents, LLMs and AI-assisted development are part of the daily workflow, and you decide where they accelerate the work and where they don't
• Set the technical bar for state management, networking and UI components, and write code that is clean, testable and reviewed
• Drive performance: profile, debug and optimise the app until it holds up in the yard, on a dealer's phone, on a weak connection
• Shape architecture and technical direction together with product managers, designers and backend engineers
• Mentor less experienced engineers, review their work and raise the standard of the whole team
• Track what moves in Flutter, Dart and mobile development, and bring tools worth adopting into the team

What you'll need

• 3+ years of professional experience building production apps with Flutter and Dart
• Proven depth in complex mobile applications: state management, networking, API integration, UI and UX components
• Command of mobile fundamentals: performance optimisation, security and accessibility
• Experience with CI/CD pipelines and agile delivery
• AI-native way of working: use tools like Claude, ChatGPT or Copilot actively in development workflow and have real judgement about their limits
• English at C1 level, and communicate clearly across an international team
• Based in Berlin or ready to relocate

Nice to have

• Experience in automotive, marketplace or B2B platform environments
• German at B2 level

What they offer

• Hybrid working: 3 days in office, 2 days remote
• 28 days annual leave
• Company pension with 20% employer contribution
• Subsidised Deutschlandticket and FitX membership or Urban Sports Club subsidy
• Structured onboarding with buddy programme
