• Define and maintain clean, scalable application architecture and reusable components.
• Build complex UI, application state, navigation, API integrations, and data-driven features.
• Implement offline-first functionality, including local persistence, caching, synchronization, conflict handling, and recovery from interrupted operations.
• Handle complex file workflows, including uploads, downloads, local storage, caching, large files, and retry/resume scenarios.
• Integrate REST APIs, authentication, push notifications, analytics, and third-party SDKs.
• Diagnose and resolve complex bugs across Flutter, native platforms, web, networking, storage, and application lifecycle.
• Optimize application startup time, rendering, memory usage, network usage, and overall performance.
• Write unit, widget, and integration tests and maintain high engineering standards through code reviews.

About you

• 5+ years of software development experience, with strong production experience in Flutter/Dart.
• Proven experience shipping and maintaining Flutter applications on iOS and Android, with Flutter Web experience.
• Strong knowledge of Flutter internals, widget lifecycle, rendering, asynchronous programming, isolates, and performance optimization.
• Strong understanding of application architecture and design patterns such as Clean Architecture, MVVM, or similar.
• Strong experience with state management such as BLoC/Cubit, Riverpod, Provider, or equivalent.
• Experience with local persistence using SQLite, Drift, Isar, Hive, or similar.
• Experience designing offline data synchronization, retry mechanisms, conflict resolution, and connectivity-aware workflows.
• Strong experience with file handling, storage, uploads/downloads, permissions, and cross-platform differences between mobile and web.
• Strong knowledge of REST APIs, JSON serialization, authentication, error handling, and networking.
• Familiarity with native Android/iOS concepts and Flutter platform channels.
