We're looking for a Senior React Native SDK Engineer to build cross-platform mobile SDKs enabling large hotel brands and enterprise customers to embed Canary's platform into their own React Native applications. You'll own the Canary React Native package, building Swift View Managers (iOS) and Kotlin View Managers (Android) that expose our native Canary Kit SDK to React Native. Beyond building the SDK, you'll work directly with enterprise customers to integrate it into their apps—debugging issues, providing technical guidance, and ensuring smooth rollouts.

The role requires deep React Native expertise, native development skills for robust bridges, and strong communication skills for client-facing work.

• SDK Development
• Own the design, development, and maintenance of Canary's React Native SDK that powers guest and staff experiences for large hotel brands.
• Build and maintain Swift View Managers (iOS) that bridge Canary Kit to React Native.
• Build and maintain Kotlin View Managers (Android) that bridge the Android SDK to React Native.
• Create best-in-class developer experiences: clear Type Script APIs, custom React hooks, robust samples, and documentation.
• Ensure feature parity and consistent behavior across iOS and Android platforms.
• Client Integration & Support
• Work directly with enterprise customers to integrate the SDK into their React Native applications.
• Debug complex integration issues across different React Native versions, Expo vs bare workflow, and client app architectures.
• Provide technical guidance and code reviews to client engineering teams during integration.
• Build sample apps and integration guides tailored to specific customer requirements.
• Collaboration & Quality
• Partner with native iOS and Android engineers to coordinate SDK releases and API contracts.
• Partner with Product and Design to scope, sequence, and ship customer-impacting work.
• Establish SDK versioning, release processes, and semantic change management for npm packages.
• Improve code quality through testing (Jest, @testing-library/react-native), automation, and thoughtful architecture.
• Drive operational excellence including crash analytics and debugging across platforms.

• 5+ years building mobile applications, with at least 3+ years focused on React Native application development.
• Deep understanding of React Native internals: bridge architecture, native module lifecycle, threading, and performance optimization.
• Proven experience building native modules and View Managers for React Native (both iOS and Android).
• Strong Type Script skills with experience publishing and maintaining npm packages.
• Working knowledge of Swift for iOS native bridge development.
• Working knowledge of Kotlin for Android native bridge development.
• Experience debugging complex issues across different React Native versions and app configurations (Expo, bare workflow, monorepos).
• Experience with React Native build tooling:
  Cocoa Pods
  , Swift Package Manager (SPM),
  Gradle
  , and Expo.
• Strong communication skills for working directly with external engineering teams during integrations.
• Quality mindset:
  Jest
  , @testing-library/react-native
  , automation, and observability best practices.
• Self-starter who thrives in ambiguity and can context-switch between SDK development and client support.

• Experience designing and shipping public SDKs consumed by external developers.
• Deep expertise in either iOS (Swift/Swift
  
  UI) or Android…
