  • Implement in-app payment integration using Apple App Store and Google Play billing systems
  • Connect mobile payment flows with backend services and external systems (e.g., CRM / licensing)
  • Ensure secure handling of purchase validation and entitlement activation on mobile
  • Collaborate with the client’s backend and product teams to align payment logic and user flows
  • Contribute to overall mobile app stability and code quality within the React Native codebase

Requirements:

  • Strong hands-on experience with React Native using Expo (including Dev Client / Continuous Native Generation)
  • Solid experience working with a shared TypeScript codebase across iOS and Android (web experience is a plus)
  • Experience integrating mobile apps with CRM or licensing backends (e.g., Salesforce)
  • Experience with Zustand (or similar lightweight state management) for centralized app logic
  • Experience integrating GraphQL APIs using Apollo Client
  • Proven experience implementing Apple App Store & Google Play in-app purchases / subscriptions, including purchase validation and entitlement handling
  • Understanding of mobile background services and push/foreground/background data handling
