React Native Mobile Application Developer
About The Position
Xentity is seeking to fill a React Native Mobile Application Developer position to lead the development and continued enhancement of mobile applications supporting the wildland fire community. The developer will be responsible for designing and implementing mobile experiences used by field personnel and fire management teams, with an emphasis on reliable operation in challenging environments where connectivity may be limited or unavailable. The position will focus primarily on React Native mobile application development while also contributing to Xentity's React-based web applications. The successful candidate will have hands-on experience developing and supporting at least one production mobile application that has been published to the Apple App Store or Google Play Store and will be able to demonstrate their specific development contributions to that application. The developer will work extensively with React Native, offline application capabilities, local data storage, mobile mapping, and Esri ArcGIS technologies. The role requires an understanding of the complete mobile application lifecycle, including local development, testing, application configuration, signing, builds, and store submission processes. The developer will not be responsible for operating the mobile CI/CD deployment pipeline, but must have sufficient knowledge of mobile build and deployment processes to define requirements, troubleshoot issues, and effectively support the team responsible for mobile CI/CD.
