Your expertise in React and React Native will drive the creation of cutting‑edge solutions that delight our users.

What You’ll Do:

• Configure and integrate native SDKs on iOS: Firebase (messaging/APNs, analytics, App Check), AppsFlyer, AppLovin MAX, Google Sign-In, the Facebook SDK and Intercom.
• Implement App Tracking Transparency, SKAdNetwork, privacy manifests, deep links and universal links.
• Design iOS alternatives for features built on Android‑only APIs, with product.

What you need to have:

• 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.
• Strong knowledge in TypeScript and JavaScript.
• 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).
• Strong problem‑solving skills and comfort in a fast‑paced environment.

Nice‑to‑Have:

• Experience with rewards, offerwall, gaming or ad‑monetised apps and how they fare in App Review.
• WebView‑based hybrid apps (JS‑to‑native messaging, cookie and session handling).
• 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?
