Developer - React Native - US

The React Native Developer is responsible for building high-quality, performant, maintainable mobile applications for iOS and Android using the React Native framework. This role involves delivering feature-rich user experiences, integrating with backend and BFF services, implementing secure mobile interactions, performing advanced debugging, and ensuring smooth releases. The developer will work closely with architects, backend teams, QA, and DevOps to deliver a modernized, production-grade mobile application.

Key Responsibilities

1. Mobile Application Development

Design and implement end-to-end mobile features , screens, flows, and reusable components in React Native.

Develop responsive UIs that adapt to different device sizes, orientations, and accessibility settings.

Implement pixel-perfect UI based on Figma/Sketch/Adobe XD designs using styling best practices.

Utilize platform-specific modules when needed (e.g., file system, camera, Bluetooth, biometrics).

Implement advanced navigation flows using React Navigation (multi-stack, tabs, modals, deep linking).

Ensure all features run smoothly on both iOS and Android with full cross-platform compatibility.

2. State Management & Data Integration

Implement state management using Redux, Redux Toolkit, Zustand, Recoil, Jotai, or MobX (depending on architecture).

Integrate the mobile application with REST/GraphQL endpoints via Axios, Fetch, or Apollo.

Implement caching, offline support, and retry logic for unstable network conditions.

Handle secure storage of tokens/credentials using Keychain/Keystore.

3. API, BFF & Backend Integration

Work closely with BFF developers to consume consolidated backend services.

Handle pagination, data transformation, error codes, and API response normalization.

Implement authentication/authorization flows:

OAuth2

JWT tokens

Multi-factor authentication (MFA)

Ensure API calls follow best practices for performance, security, and resiliency.

4. Performance Optimization

Conduct performance profiling and optimize:

Rendering cycles

Component re-renders

JavaScript thread bottlenecks

Memory usage and leaks

Bundle size and startup time

Implement lazy loading, deferred loading, and code splitting where appropriate.

Optimize animations using Reanimated or Native Driver.

5. Testing & Quality Assurance

Write unit tests using Jest , React Native Testing Library, and Mocks.

Implement integration and UI tests using Detox or Appium.

Collaborate with QA engineers to support test automation and regression testing.

Ensure proper error handling, graceful degradation, and fallback UIs.

6. Native Module Integration & Bridging (Intermediate to Advanced)

Integrate with native iOS/Android modules when React Native doesn’t provide required functionality.

Understand how to bridge Swift/Kotlin/Java modules into JavaScript.

Work with hardware features (GPS, camera, sensors, file system, biometrics).

Troubleshoot native-level crashes and logs using Xcode/Android Studio.

7. Build, Deployment, and DevOps Collaboration

Work with DevOps on CI/CD pipelines for mobile apps (App Center, Fastlane, Azure DevOps).

Configure app signing, certificates, provisioning profiles, and versioning.

Support creation of release builds for TestFlight, Google Play Internal Test Track, or OTA (CodePush).

Troubleshoot build issues and maintain build scripts.

8. Security, Compliance & Data Governance

Implement secure coding practices:

Secure API calls

Jailbreak/root detection

Obfuscation/minification

Secure storage for credentials

Work with architects to ensure compliance with:

Data separation

Role-based access controls (RBAC)

Encryption at rest/in transit

App transport security requirements

Adhere to enterprise mobile security guidelines (OWASP Mobile ASVS).

9. Documentation & Collaboration

Create and maintain documentation for:

Components

Feature flows

API contracts

Edge cases

Technical constraints

Participate in grooming, sprint planning, story estimation, and retrospectives.

Collaborate with designers to validate UI/UX requirements.

Participate in code reviews and enforce coding standards.
