Description
We're looking for a Senior React Native engineer to lead the development, maintenance, and optimization of a React Native SDK built using React Native Bridge and Turbo Modules. The ideal candidate will have hands-on experience successfully building and publishing a React Native SDKeither to package managers like NPM or Yarn, or through GitHub releases. Youll be responsible for the entire SDK lifecycle from development and deployment to compliance and long-term maintenance. This role demands deep expertise in React Native, including Bridge and Turbo Modules, as well as strong proficiency in native mobile development (Kotlin for Android and Swift/Objective-C for iOS). A solid understanding of API integration and the ability to troubleshoot complex cross-platform issues end to end is essential. Requirements Design and Develop React Native SDKs -Build robust, scalable, and modular SDKs using React Native Bridge and Turbo Modules, following industry best practices. Maintain and Optimize SDK Codebase - Continuously improve performance, stability, and maintainability of the SDK, including refactoring and optimizing legacy code. Manage SDK Release Lifecycle - Own the full release process from versioning and packaging to publishing the SDK on NPM or Yarn and handling updates. Ensure Cross-Platform Compatibility - Develop and test the SDK to work seamlessly across both iOS and Android platforms, accounting for platform-specific nuances. Implement Native Modules - Write and integrate native modules in Kotlin (Android) and Swift/Objective-C (iOS) where necessary to extend React Native capabilities. Collaborate with Product and Engineering Teams - Work closely with internal teams to define SDK features, provide technical guidance, and support integration into various apps. Troubleshoot and Debug Issues - Diagnose and resolve complex bugs and performance issues across the entire tech stack from JavaScript to native layers. Ensure Security and Compliance - Build SDKs that meet data privacy, platform compliance, and security standards required for public distribution. Document SDK Usage and Integration - Write clear, comprehensive documentation and examples to help external developers easily integrate and use the SDK. Stay Up to Date with Industry Trends - Keep current with the latest developments in React Native, mobile platforms, and SDK tooling to continuously improve the product. Lead Architecture Decisions - Define the SDK's architecture and design patterns to ensure scalability, modularity, and long-term maintainability. Monitor SDK Usage and Performance - Set up analytics and monitoring tools to track adoption, usage patterns, and performance in real-world applications. Provide Developer Support - Assist internal and external developers with integration issues, troubleshooting, and best practices for using the SDK. Review Code and Enforce Quality Standards - Conduct thorough code reviews and enforce coding standards, test coverage, and CI/CD practices across the SDK repository. Write Unit, Integration, and E2E Tests - Develop comprehensive test suites to ensure code reliability and reduce regressions during updates and releases. Integrate CI/CD Pipelines - Set up and maintain automated build, test, and release pipelines for the SDK using tools like GitHub Actions, Bitrise, or CircleCI if required. Evaluate and Integrate 3rd Party Libraries - Research, evaluate, and safely incorporate third-party libraries where needed, ensuring minimal bloat and maximum stability. Manage SDK Versioning and Backward Compatibility - Carefully handle version updates, changelogs, and ensure that new releases maintain backward compatibility or provide proper migration paths. Contribute to Internal Tools and Templates - Create reusable templates, CLI tools, or internal documentation that streamline development and testing of apps using the SDK. Desired Skills: Expertise in React Native - Deep understanding of the React Native framework, especially around performance optimization, modular architecture, and ecosystem tools. Proficiency with React Native Bridge and Turbo Modules - Experience building and exposing native modules to JavaScript using both the legacy bridge and the newer Turbo Modules architecture. Native Mobile Development - Proficient in one or both of the following: Android (Kotlin/Java) and iOS (Swift/Objective-C), with the flexibility to contribute across both: Android: Kotlin and/or Java iOS: Swift and Objective-C Ability to write, maintain, and debug native code for both platforms. SDK Development Experience - Proven experience designing, developing, publishing, and maintaining SDKs or libraries used by other developers. Package Management Tools - Experience publishing packages to NPM, Yarn, or similar, including semantic versioning, changelogs, and dependency management. API Integration & Data Handling - Strong understanding of REST/GraphQL APIs, WebSockets, and secure data handling (OAuth, encryption, etc.). Testing and QA - Proficiency in writing unit, integration, and E2E tests using tools like Jest, Detox, and native test frameworks. CI/CD for Mobile SDKs - Familiarity with CI/CD systems like GitHub Actions, CircleCI, Bitrise, or Fastlane for automated builds, testing, and deployment. Debugging & Performance Profiling - Skilled at diagnosing performance bottlenecks and platform-specific bugs using tools like Flipper, Xcode Instruments, and Android Studio Profiler. Cross-Platform Tooling Knowledge - Familiarity with tools like CodePush, App Center, Firebase, Sentry, etc., to improve release management and error tracking.
