Jobbeschreibung

Join the ride!

You own our consumer mobile app end to end, from architecture to store release. One

React Native codebase ships to iOS and Android, and you are accountable for its code, its

native layer, its releases and the app side of every API contract.

The app is how our customers experience the product every day. Your work keeps it fast,

stable and safe to change, and raises its quality and release confidence with every

version.

This position is Berlin based.

Your Responsibility

• Own the app's architecture, code quality, performance and stability on iOS and Android
• Build and maintain native modules in Swift or Kotlin where React Native is not enough

• Build and maintain automated test coverage and run it in CI
• Keep the codebase's AI tooling in version control and review it like code
• Effectively deploy and use AI agents.

Your Experience

• 5+ years of React Native in production, shipped to both the App Store and Google Play
• Solid native knowledge: Swift or Objective-C with Xcode, Kotlin or Java with Android, Studio and Gradle
• Strong TypeScript and JavaScript, and experience with modern state management
• REST API integration with deliberate handling of async, offline and error states
• Automated testing with Jest and Detox or Maestro, run in CI such as GitLab CI or GitHub Actions
• Store releases with fastlane: signing, pre-release test tracks and staged rollouts
• Fluent in English, and eligible to work in Germany

Highly desired

• Experience in mobility, logistics or another operations-heavy consumer product
• Map-heavy apps: location permissions, push notifications and deep linking
• Payment SDK integration in a consumer app
• Comfortable reading backend code in a typed language and SQL
• Accessibility and localisation for a multi-language audience
• Daily use of AI coding agents, reviewing their output like any pull request

Nice to have

• A valid driving licence (EU category B or equivalent). Testing the product includes trip on the road.
