Requirements

We are looking for a highly experienced React Native engineer to develop, maintain, and optimize our mobile application infrastructure. The ideal candidate must have successfully released a product into the Apple App Store and Google Play Store and must be capable of owning the entire mobile development lifecycle, including deployment, compliance, and ongoing maintenance.This role requires deep expertise in React Native, strong knowledge of API integrations, and the ability to debug complex issues across frontend and backend systems. Since the entire backend is built on AWS, the ideal candidate must also be comfortable integrating AWS services into a mobile application.

Responsibilities:

• Work with cross-functional teams, including designers, product managers, and backend engineers, to develop world-class mobile applications.

• Own the mobile application development lifecycle from planning, development, and testing to deployment and compliance with Apple App Store and Google Play requirements.
• Design, develop, and optimize high-performance, scalable, and maintainable React Native applications for iOS and Android.
• Translate designs and wireframes into pixel-perfect, high-quality mobile applications.
• Own compliance responsibilities, ensuring that all app store requirements, security guidelines, and best practices are met.
• Ensure the highest level of performance, security, and responsiveness for the mobile application.
• Integrate and debug communication between frontend and backend services, using tools like Fiddler to diagnose and resolve API issues.
• Develop and integrate APIs with a strong focus on RESTful APIs, GraphQL, and WebSockets for real-time data handling—this is a critical requirement.
• Integrate AWS backend services such as AWS Amplify, AWS AppSync, AWS Lambda, AWS API Gateway, AWS Cognito (for authentication), S3 (for storage), and DynamoDB.
• Implement and maintain CI/CD pipelines for mobile applications using Fastlane—this is a core requirement.
• Work with debugging and performance profiling tools, including Flipper, Reactotron, Xcode Instruments, and BrowserStack for robust testing across multiple devices and network conditions.
• Ensure app stability by writing and maintaining unit tests, integration tests, and end-to-end tests using Jest and Detox.
• Implement push notifications, deep linking, and in-app messaging as required.
• Handle offline data storage and synchronization strategies to support a seamless user experience. Stay updated with emerging mobile development trends, frameworks, and best practices.
• Write and maintain technical documentation, process flows, and architectural diagrams.
  
  
  
  Desired Skills:
  
  
• 5+ years of proven experience as a React Native Developer with at least one product successfully released to the Apple App Store and Google Play Store.

• Expertise in React Native, including core APIs, hooks, animations, and performance optimizations.
• Strong proficiency in JavaScript, TypeScript, and ES6+.
• Hands-on experience with state management using Redux, Recoil, or Context API.
• Strong knowledge of RESTful APIs, GraphQL, and WebSockets for real-time data handling (critical skill).

• Experience debugging frontend-to-backend communication using Fiddler, Charles Proxy, or similar tools.
• Experience integrating third-party libraries and frameworks, such as React Navigation, Native Base, Reanimated, and FlashList.
• Hands-on experience handling offline data storage and synchronization techniques.
• Proficiency in debugging and performance profiling tools, including Flipper, Reactotron, Xcode Instruments, and BrowserStack.
• Expert-level experience with Fastlane, ensuring smooth CI/CD pipelines and automated deployments.
• Experience integrating native SDKs (e.g., HealthKit, Google Fit, Camera Bluetooth, Maps).
• Familiarity with push notifications, deep linking, and in-app messaging.
• Proficiency in unit testing (Jest, React Native Testing Library) and end-to-end testing (Detox, Appium).
• Experience publishing and maintaining apps in the App Store and Google Play, including handling updates, compliance requirements, and approvals.
• Strong understanding of Git-based version control systems (GitHub, Bitbucket).
