SDE II - React Native

Role

We are hiring a React Native developer to build flexible, well-structured front-end architecture and high-performance mobile applications capable of rendering large quantities of data. The role covers building UI components, integrating native APIs and modules, optimizing performance, and maintaining CI/CD/testing workflows for Android and iOS.

Key Responsibilities

• Design and implement user interface components for JavaScript/TypeScript-based web and mobile applications using the React ecosystem.
• Work with wireframes and design systems (Figma, Sketch, Adobe XD) to deliver consistent UI/UX.
• Integrate native modules and use platform APIs for Android and iOS.
• Write automated unit and integration tests with frameworks such as Jest, Detox, or Cypress/Appium.
• Optimize bundle size and startup time using techniques like the Hermes engine, lazy loading, and code splitting.
• Build reusable front-end modules and implement smooth animations and gesture handling.
• Use Redux and middlewares to manage state and improve performance.
• Integrate third-party libraries, APIs, payment gateways, and services (Firebase, AWS Amplify, Stripe, Razorpay, Apple Pay, Google Pay).
• Implement CI/CD pipelines and automated builds/deployments (Fastlane, Bitrise, GitHub Actions, Jenkins, etc.).
• Handle deep linking and navigation (React Navigation, Dynamic Links, Universal Links).
• Debug and profile front-end performance using tools like Flipper and React Profiler.
• Coordinate with cross-functional teams to deliver features on time and within budget.
• Keep up with React Native updates, libraries, and AI-assisted development tools to improve productivity.
