Software Engineer- (React & React Native Developer)

Role Overview:

As a React & React Native Developer (0-2 years’ experience), you will collaborate with UI/UX designers, backend engineers, and product owners to architect, develop, and maintain both web and mobile codebases. You’ll be instrumental in translating designs into pixel-perfect interfaces, optimizing performance, and ensuring robust offline and real-time data handling

Key Responsibilities:

● Component Development

○ Create modular, reusable UI components in React and React Native.

○ Translate Figma/Sketch designs into pixel-perfect layouts.

● API Integration

○ Consume RESTful and GraphQL services with error handling, caching, and retry logic for offline support.

○ Implement JWT token management and robust data synchronization.

● Performance & Optimization

○ Profile and optimize rendering (e.g., FlatList/SectionList), bundle size, and network calls.

○ Apply code-splitting, lazy loading, and Redux performance tuning.

● Testing & QA

○ Author unit and integration tests with Jest and React Testing Library.

○ Build end-to-end suites using Cypress/Playwright for web and Detox/Appium for mobile.

● CI/CD & Releases

○ Configure pipelines (GitHub Actions, CircleCI, Jenkins) and mobile delivery (Fastlane for TestFlight/App Store & Play Store).

○ Manage versioning, branching strategies, and release notes.

● Collaboration & Support

○ Participate in Agile ceremonies, sprint planning, and peer code reviews.

○ Monitor production issues via Sentry/Bugsnag, analyze logs, and deploy hotfixes.

Required Qualifications:

● React & React Native Expertise

○ Deep understanding of component lifecycle, reconciliation, Hooks (useReducer, useMemo, useCallback), and Context API.

● State Management

○ Proficient with Redux Toolkit (slices, middleware), MobX, or Recoil.

● Styling

○ Experience with CSS-in-JS (styled-components, Emotion), Tailwind CSS, or BEM.

● Mobile App Delivery

○ iOS and Android build processes, provisioning profiles, and App Store/TestFlight/Google Play deployments.

● Native Module Integration

○ Bridging in Objective-C/Swift and Java/Kotlin for custom functionality.

● Performance Tuning

○ JS thread profiling, memory leak detection, and efficient list rendering strategies.

● Modern JavaScript & TypeScript

○ ESNext features (async/await, dynamic imports, proxies) and strong TS skills (generics, discriminated unions,

mapped types).

● Tooling & Linting

○ Custom ESLint rules, Prettier, Husky, and lint-staged for code quality enforcement.

● Testing Frameworks

○ Jest with coverage thresholds, React Testing Library best practices, and E2E tools (Cypress/Playwright, Detox/Appium).

● Monitoring & Analysis

○ Lighthouse audits, bundle-analyzer, and error tracking with Sentry or Bugsnag.

● Data Storage & Offline

○ AsyncStorage, MMKV, SQLite/Realm, and conflict resolution sync patterns.

● Build & Bundler

○ Webpack and Metro customizations, tree-shaking, and code splitting.

● CI/CD & DevOps Basics

○ Familiarity with GitHub Actions, CircleCI/Jenkins, Fastlane, and Docker. Kubernetes knowledge is a plus.

● Version Control & Monorepo

○ Advanced Git (merge/rebase), Lerna or Yarn Workspaces.

● Agile Practices

○ Backlog grooming, estimation (Planning Poker), and JIRA/Azure DevOps.

Preferred Experience:

● Google Maps APIs, KML exports, and geospatial visualizations.

● Flask or Node.js backend collaboration.

● Docker and Kubernetes orchestration
