React Native Developer

About the role

ClassOwl is a school-management system used by schools. We are hiring a Middle+ / Senior React Native Developer to work on the existing mobile product for iOS and Android

The application is built with React Native CLI and TypeScript. Most tasks involve extending and improving the current application: adding product functionality, integrating APIs, working with authentication, push notifications and device features, and investigating issues reported from staging or production

The developer will take part in a feature from clarification and estimation to implementation, code review and release. It is important to understand an existing codebase, make changes carefully, account for differences between iOS and Android, and handle changes in network and application state reliably
