Job Title: Mobile
Developer

Experience: 4-5

About the Role

We are looking for a Mobile Developer with 3–5 years of experience in
React Native to join our engineering team. You will own the development,
maintenance, and enhancement of our cross-platform mobile application used
across 30+ client organizations.

The app operates in demanding field environments — offline mode, low
connectivity, GPS tracking, image capture, bulk data sync, and real-time call
integration. You will work closely with backend engineers and product managers
to deliver features that directly impact field collections performance.

Key Responsibilities

· Build and maintain cross-platform mobile features in
React Native (iOS + Android) aligned with backend APIs.

· Implement offline-first data sync mechanisms for field
use cases where connectivity is unreliable.

· Integrate with REST APIs (Spring Boot 3.x backend)
including JWT/OAuth2 authentication flows via Keycloak.

· Implement Firebase Cloud Messaging (FCM) for push
notifications — activity alerts, call assignments, settlement approvals.

· Work with device capabilities: GPS location tracking,
camera (photo/document capture), file system (bulk upload).

· Build call center integrations: click-to-call flows,
call status tracking.





· Maintain per-client build configurations — 30+
org-specific auth configs, themes, and feature flags.

· Write clean, testable component code; participate in
code reviews and maintain quality standards.

· Optimise app performance: memory, bundle size,
startup time, list rendering for large datasets.

· Collaborate with backend and product teams in an agile
delivery environment.
