Job Requisition Id: 65716
Location: IN Bangalore, KA, IN
Responsibilities
- Build and enhance features for a hybrid mobile application targeting iOS, Android, and PWA using Angular, Ionic, and Capacitor.
- Develop standalone Angular components with lazy-loaded routing, Angular Signals, and reactive patterns (RxJS) to deliver responsive and maintainable UIs.
- Implement and consume native device capabilities (camera, geolocation, push notifications, filesystem, and platform sensors) through Capacitor plugins.
- Write and maintain unit tests using Jest with Angular TestBed, MockStore, and HttpClient testing utilities to ensure code reliability.
- Work within an NX monorepo containing multiple feature and shared libraries.
- Translate high-level designs into low-level implementation, creating models, services, and facades that align with established architectural patterns.
- Monitor and optimize mobile UI performance through lazy loading, code splitting, caching, and bundle-size management.
- Troubleshoot platform-specific issues across iOS, Android, and web, analyzing logs, native bridges, and runtime behavior.
Required Skills
- Angular 19+ (Standalone Components): Standalone component architecture, dependency injection via inject(), Angular Signals, lazy-loaded routing with guards, and HTTP interceptors.
- Ionic 7 + Capacitor 7: Hybrid mobile development with Ionic UI components, Capacitor native bridge, platform-specific behavior handling, Auth Connect, and Identity Vault.
- TypeScript 5.5+ (Strict Mode): Strong typing with interfaces, generics, type guards, strict null checks, and no implicit any.
- RxJS 7: Reactive programming with Observables, Subjects, key operators (switchMap, combineLatest, forkJoin, etc.), and subscription lifecycle management.
- NX Monorepo (pnpm): Workspace architecture with 80+ libraries, project boundaries, affected-based CI, and pnpm package management.
- Mobile and Native Patterns: Capacitor plugin integration (camera, geolocation, push notifications, filesystem), deep linking, PWA/Service Worker, and app lifecycle management across iOS, Android, and web.
- Unit Testing with Jest: Angular TestBed testing with mocking (jest.fn, jest.spyOn, provideMockStore), fakeAsync/tick, and Ionic web component schemas.
- Data Visualization: Chart.js for graphs, Google Maps API for map rendering and geofences, and D3.js for Gantt/timeline charts.
- Real-Time Communication: WebSocket integration using RxJS webSocket() for live data updates with authenticated connections.
- Internationalization (i18n): Multi-language support using TranslateModule/Transloco patterns with language selection flows and translation key conventions.
- Firebase Analytics: Custom event tracking and screen view logging integration.
- Facade Pattern: Abstraction layer over state management, encapsulating store dispatch and selector logic behind clean service APIs.
