Stellenbeschreibung:

Company Description

ABOUT YOU is one of Europe’s fastest growing e-commerce companies. Based in Hamburg and Berlin, we operate at the intersection of fashion and technology. Our mission is to rethink online shopping and make it personal and seamless. This takes more than good ideas. It takes people who take initiative and challenge the status quo. We believe in flat hierarchies, direct communication, and pragmatic decisions. No long approval chains. Just ownership, trust, and clear responsibility. We work hard, but we also believe in enjoying the ride together - over team lunches, afterwork drinks, company events, or a quick coffee in between meetings. If this sounds like you, ABOUT YOU could be the right place to bring in your perspective.

Job Description

  • Build and maintain a high-quality mobile application using Flutter for iOS and Android platforms
  • Participate as a solution architect from the very beginning of new projects; you will not just implement changes but think them through deeply and be responsible for the implementation across all stacks
  • Gain significant exposure to other teams, such as Shop Backend and Webstacks, to align solutions and drive the tech stack of all teams forward
  • Drive technical discussions forward with the team and lead architectural alignment
  • Lead by example and set coding standards, review pull requests and mentor other engineers in the team
  • Empower the team to deliver mission‑critical features in quality & time
  • Contribute to architectural decisions across multiple stacks
  • Closely collaborate with Product Managers, Designers, Testers and other stacks (Backend and Web)
  • Introduce new technologies, tools or processes that improve developer productivity and product quality
  • Debug performance and reliability issues across the stacks

Qualifications

  • 8+ years of programming experience, with at least 3 years of native or hybrid App development experience
  • Expert-level Dart & Flutter knowledge
  • CI/CD experience – Google Play Store, App Store deployments (fastlane, GitHub Actions or similar)
  • Experience with Unit and Golden Tests
  • Experience of performance optimisation and profiling (using Flutter DevTools)
  • Mobile native experience – iOS or Android
  • Experience with monitoring tools – Firebase Crashlytics, Sentry, DataDog etc.
  • Figma knowledge
  • Experience using AI (e.g. Copilot or Cursor) to speed up coding experience
  • Experience with Backend development
  • Mobile automated testing
  • Excellent problem‑solving: You can solve conceptual, non‑standard problems and exercise solid judgement based on analysing multiple sources of information
  • High autonomy and ownership: You are motivated, take matters into your own hands, and can lead a complex project or process with little oversight from your manager
  • Strong communicator: You can communicate transparently, honestly, and effectively with both technical and non‑technical stakeholders (e.g. Product, Design)
  • Team player: You actively share knowledge, inspire other team members, and aim to fulfil team goals

Nice To have

  • Experience in Web Development
  • DevOps experience (e.g. CI/CD pipelines, AWS)
