You’ll implement native modules, integrate third-party SDKs, and ensure compliance with App Store guidelines, ATT, and privacy standards in a fast-paced, hybrid-work environment.

Qualifications

• 5+ years of professional mobile or frontend experience, including 3+ years of React Native.
• At least one React Native app shipped to the App Store and maintained in production.

• Hands-on iOS tooling: Xcode, CocoaPods, signing and provisioning, TestFlight, App Store Connect.
• Experience integrating third-party native SDKs (attribution, ads, push, analytics) in React Native.
• Working knowledge of Swift or Objective-C for native modules and debugging.
• Solid understanding of App Store Review Guidelines, ATT and Apple’s privacy requirements.
• Testing experience with Jest plus a mobile end-to-end framework (Maestro, Detox or similar).

• Implement App Tracking Transparency, SKAdNetwork, privacy manifests, deep links and universal links.
• Design iOS alternatives for features built on Android-only APIs, with product.
• Write native Swift or Objective-C modules where React Native libraries fall short.
• Build the iOS release pipeline in CircleCI with fastlane: code signing, TestFlight and App Store Connect.
• Own App Store submissions and App Review, including the guidelines that apply to rewards and incentive apps.
• Keep shared code platform-agnostic so Android and iOS stay in sync.
• Maintain testing on both platforms with Jest and Maestro end-to-end tests.

Nice-to-Have:

• Experience with rewards, offerwall, gaming or ad-monetised apps and how they fare in App Review.

• Sign in with Apple.
• React web experience (React Query, MUI), to help on the web app.
• CI/CD for mobile (CircleCI, fastlane, Firebase App Distribution).
• Google Cloud and Firebase.
• Sentry or similar crash reporting.

Why Join Us?
