We are looking for an experienced React Native developer to implement marketing tracking for our iOS mobile application. You will be responsible for: Installing and configuring the Meta (Facebook) SDK in a React Native iOS app. Installing and configuring the TikTok SDK in the same app. Setting up Conversion API (CAPI) events so that key in‑app actions are tracked server-side. Tracking conversions through RevenueCat so that purchases / subscriptions are properly attributed. Requirements: Strong experience with React Native (iOS). Hands-on experience integrating marketing/analytics SDKs (e.g., Meta, TikTok) in mobile apps. Familiarity with Conversion API (CAPI) setups and event tracking flows. Experience with RevenueCat integration and event tracking is a strong plus. Ability to communicate clearly and provide brief implementation documentation (what was added, where, and how to test). Scope & collaboration: Less than 30 hours per week, expected duration less than 1 month. You will work directly with the app owner; access to codebase and relevant accounts will be provided. Please include: A short note on your past projects where you integrated Meta/TikTok tracking in React Native apps. Any examples of using RevenueCat for conversion tracking. Only apply if you have done similar work before and can start soon.
