Job description

Frontend Engineer (Flutter)

We’re looking for a Frontend Engineer to build fast, reliable, and maintainable applications used daily in our electric mobility and battery‑swap ecosystem. You will ship features end-to-end using Flutter across Android, iOS, and Web — ensuring great experience, high performance, and scalability as we grow.

What You Will Do

• Build and ship end-to-end product features in Flutter for Android, iOS, and Web.
• Translate product requirements into production‑ready UI/UX flows, reusable widgets, and clean architecture.
• Implement state management, data fetching, and API integrations (REST/GraphQL/WebSockets).
• Own app performance and reliability through profiling and proactive optimization.
• Collaborate closely with Product, Design, Backend, and QA to ensure seamless delivery.
• Maintain code quality via reviews, testing, and CI/CD best practices (feature flags, safe rollout).
• Monitor app health using Firebase tools (Crashlytics, Performance, Analytics) and iterate continuously.
• Contribute to and expand Flutter Design System (component library, theming) for consistency across products.

Experience

• 5+ years developing production‑scale apps; 3+ years hands‑on with Flutter/Dart.
• Demonstrated success delivering features across multiple platforms (Android, iOS, Web).
• Experience with other frontend frameworks (React Native/React/Next.js) and Android native (Kotlin) is a strong plus.

Skills

• Strong in state management patterns (Bloc/Cubit, Riverpod, Provider, etc.).
• Skilled in API integration using Dio/Retrofit/http with robust error handling and caching.
• Solid UI/UX execution: responsive layouts, animations, accessibility, theming.
• CI/CD awareness (GitHub Actions) and release workflows (multi‑flavor, environment configs).
• Firebase knowledge: Auth, Firestore, Crashlytics, Performance, Analytics, Remote Config.
• Competent with Flutter DevTools for performance/memory/network debugging.
• Strong communication and teamwork with cross‑functional partners.

Nice to Have

• Experience building or maintaining a Flutter Design System (design tokens, reusable components).
• Knowledge of Flutter Web deployment nuances (routing, asset optimization, web constraints).
• Comfortable using AI‑driven tooling to improve developer productivity (assistants, auto‑tests, code suggestions).
