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.

Authentication:

General:

·       Understanding of REST API design; ability to read
backend API contracts
