About The Job

We have launched Keet Mobile on iOS and Android, bringing our full P2P technology stack to everyone. Keet Mobile is not your average app: it’s heavy lifting is performed by a custom JS runtime specially designed for peer-to-peer usage (in fact, it reuses 100% of Keet Desktop’s code!). The UI logic, on the other hand, is 100% React Native, giving us flexibility and the ability to iterate quickly.

We believe this pattern opens the door to huge possibilities in the future, and we need your help getting there!

You will:

• Build and polish features across chat, voice and video calls, media sharing, device pairing and identity backup
• Integrate native platform capabilities such as push notifications, camera, bio-mics and background tasks on both iOS and Android
• Profile and optimise performance on real devices, including startup time, long chats, media handling, battery and network use
• Write unit and end‑to‑end tests, and help keep releases stable through CI and crash reporting
• Work closely with the core P2P, design and product teams, and review code with a high bar for quality
• Significant experience with React Native, Redux for state management and Redux‑Saga
• Highly proficient in JavaScript and ES6+.
