Mobile App Developer

KEY RESPONSIBILITIES
Core Frontend (Angular + Ionic)

• Angular 16/17+ fundamentals: standalone components, routing & lazy loading, dependency injection, signals or RxJS.
• Minimum 3+ years of hands-on Angular development experience required.
• TypeScript strict mode, strong typing of API/DTOs, guards/type-narrowing in templates (strictTemplates).
• Minimum 2+ years of TypeScript development experience required.
• Ionic components & patterns: navigation, lifecycle (Ionic vs Angular), ion-img, virtual scroll, theming with CSS variables.
• Minimum 2+ years of Ionic framework experience required.

Capacitor Platform & Plugins

• Capacitor lifecycle and bridge basics; wrapping plugins behind services.
• Official plugins (v5 line): App, Filesystem, Geolocation, Network, Clipboard, Share, Local Notifications.
• Community/third-party plugins and compatibility strategy, e.g., @capacitor-community/barcode-scanner, wifiwizard2, capacitor-native-settings.
• Migrating away from Cordova plugins; replacing cordova-plugin-advanced-http with CapacitorHttp.
• Permissions flows (Android/iOS) for camera, location, notifications; graceful "ask/deny" UX.

Android Native (must-have)

• Gradle/AGP basics; versionCode/versionName; target/compile SDK alignment (SDK 34+).
• Network Security Config for dev cleartext hosts; keeping cleartext off in release.
• BroadcastReceiver and Android 13/14 changes (e.g., RECEIVER_EXPORTED/NOT_EXPORTED, FLAG_IMMUTABLE), foreground services.
• Manifest hygiene: permissions, queries, FileProvider, intent filters.
• R8/ProGuard rules for reflection-heavy libs; reading Logcat/ANR traces.

iOS Native (must-have)

• Xcode targets/schemes, signing, provisioning, device testing.
• capabilities & privacy strings (camera, location, NFC, etc.).
• App Transport Security (ATS) exceptions (minimize, scope narrowly).
• Understanding of background modes when relevant (BLE, location, etc.).
• Reading device logs (Xcode console) and crash reports.

Networking & Security

• HTTP stacks: Angular HttpClient (web) vs CapacitorHttp (native) and when to use each.
• CORS vs native networking differences; cookies vs token auth.
• TLS/SSL basics, self-signed certs in dev, pinning awareness.
• Secrets handling (env files, build-time injection, never hardcode).

API / Storage

• IndexedDB/Capacitor Storage, simple repositories, sync strategies.
• DTO → Domain mapping, validation, and error boundaries.

Performance & UX on Mobile

• Bundle control: Angular budgets, code-splitting, dynamic import of heavy libs.
• Profiling start-up & runtime (Chrome DevTools remote debugging, Android Profiler, Instruments).
• List virtualization, image lazy-loading, avoiding layout thrash.
• Perceived performance: splash → first paint, skeletons, optimistic UI.

Testing & Quality

• Unit tests for services/components; mocking Capacitor plugins.
• E2E (Playwright/WebKit/Android emulator or BrowserStack).
• Linting (ESLint), type checks, commit hooks (Husky + lint-staged).
• Error monitoring & analytics (Sentry/Crashlytics), release health.

Build, CI/CD, and Release Management

• npm dependency hygiene (peer deps, overrides), workspace awareness.
• Automated version sync + Android/iOS) and build numbers.
• GitHub Actions/GitLab CI: lint + typecheck → build, Capacitor sync, platform builds.
• Store packaging: app icons/splash, privacy labels, Play/App Store submission checklists.

Troubleshooting Playbook (specific to your app's issues)

• Resolve plugin/core mismatches (keep all @capacitor/* on the same major).
• Fix Android 14 receiver crashes (Share/others) or remove/patch until upgrading to Capacitor 6+.
• Cleartext errors: apply scoped Network Security Config for local IPs only.
• Consolidate HTTP to CapacitorHttp; remove Cordova HTTP to avoid double stacks.
• Barcode/Camera permission prompts and cleanup on view leave.

Nice-to-Have Specialties

• BLE/Wi-Fi provisioning flows (e.g., WifiWizard2 nuances on Android 10+).
• App architecture with Component Store/NgRx for larger features.
• Internationalization, accessibility (screen readers, focus management).
• Fastlane for automated signing/builds, Play/App Store APIs.

Minimum 3-4 years of mobile app development experience required.

Bachelor's degree required for this position.
