Skills requirements

Must-have (table stakes)

Platform & language (pick the primary track)

• Android: Kotlin (preferred), Java for legacy; Android SDK, Jetpack (ViewModel, Navigation, Room, WorkManager), Jetpack Compose
• iOS: Swift (preferred), UIKit + SwiftUI; Xcode, Combine or Swift Concurrency (async/await)
• Cross-platform: Flutter + Dart or React Native + TypeScript (New Architecture: Fabric / TurboModules)

Core engineering

• App architecture: MVVM, Clean Architecture, modularization
• State management relevant to stack (StateFlow / Compose state, Combine, Riverpod/BLoC, Redux/Zustand)
• Networking: REST, JSON, error handling, retries, offline-first patterns
• Local storage: Room / Core Data / SQLite / Hive / SharedPreferences / Keychain-Keystore
• Git (branching, PRs, code review)
• Debugging and profiling (Android Studio Profiler / Instruments)
• Publishing: App Store Connect + TestFlight and/or Google Play Console (AAB, signing, staged rollout)

Quality & process

• Unit + UI testing (JUnit/Espresso/XCTest/Widget tests/Detox/Maestro)

• Basic mobile security: secure storage, certificate pinning awareness, no secrets in the client

Strongly preferred

• CI/CD: GitHub Actions, Bitrise, Fastlane, Codemagic, or Xcode Cloud
