SDK Developer - React & React Native

Job Description:

Responsibilities

• Design and develop robust, well-documented SDKs for web and mobile platforms using React and React Native.
• Collaborate with backend engineers to understand APIs and translate them into intuitive SDK interfaces.
• Build, test, and publish SDK packages — managing versioning, changelogs, and release pipelines.
• Write clear developer-facing documentation, usage guides, and code samples.
• Work closely with product and design teams to ensure seamless developer experience (DX).
• Review backend code and REST/GraphQL API contracts to ensure SDK compatibility.
• Identify and resolve performance bottlenecks, bugs, and integration issues reported by SDK consumers.
• Contribute to iOS and Android native integrations as needed, bridging native modules with React Native.

Qualification & Experience 

• React & React Native
• 3–5 years of hands-on experience with React for web and React Native for cross-platform mobile development.
• Deep understanding of component lifecycle, hooks, state management (Redux / Context API), and performance optimisation.
• Proficient in publishing and consuming npm packages; familiar with module bundlers (Webpack, Metro, Rollup).
• Strong grasp of JavaScript/TypeScript — generics, type utilities, strict-mode best practices.
• SDK Development Experience
• Demonstrable experience having shipped at least one production-grade SDK or developer library.
• Familiarity with SDK design principles: backward compatibility, versioning (SemVer), minimal surface area, and ergonomic APIs.
• Experience writing unit, integration, and end-to-end tests for SDK code.
• Brownie Points (Good to Have)
• iOS & Android Native Experience
• Exposure to native iOS development (Swift / Objective-C) or Android development (Kotlin / Java).
• Experience writing React Native bridge modules or Turbo Modules to expose native functionality.
• Understanding of platform-specific build toolchains — Xcode, Gradle, CocoaPods, and the App Store / Play Store release process.
