Mobile App Engineer (React Native)

Tasks

What You'll Be Doing

Joining as an early-stage Mobile Software Developer, you'll take heavy ownership of the app's architecture and user experience. You will build out our mobile technical foundation from scratch, making the key decisions on UI architecture, state management, API integration, and performance monitoring.

  • Own the product beyond the interface: You will take full accountability for your features from end to end. This means managing complex local state, building smooth user journeys, and ensuring native-level performance. You're going to write, ship, and iterate on your own code.
  • Design scalable, smart architecture: You will build out a robust mobile foundation using patterns like MVVM or TCA to connect seamlessly with our Effect-based backend and AI systems. Expect to tackle tough engineering challenges involving real-time synchronization, offline-first capabilities, and streaming AI responses.
  • Keep the technical bar high: You'll actively hunt down and fix performance issues like sluggish render cycles or slow app startup times. At the same time, you'll push for better maintainability, strict type safety, and a consistent UX throughout the codebase.

Requirements

What We're Looking For

  • Strong experience with TypeScript & React Native.
  • End-to-End Ownership: You don’t throw things over the wall. You own your features until they are running successfully in production and used by real learners.
  • Startup experience: You’re comfortable in fast-paced, evolving environments
  • Balanced AI approach: You knew how to code before Cursor and Claude Code, but understand how to leverage them effectively
  • Product passion: High identification with our mission to transform education
