React Native Mobile Application Developer
Start Date: November 2026
Job Type: Full-Time
Labor Category: TECH
Location: Remote
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.

- Troubleshoot mobile build, device, operating system, performance, connectivity, and application issues and work with the appropriate team members to resolve them.
- Help establish approaches for offline data storage, synchronization, caching, and recovery for field applications.
- Support application testing across iOS and Android devices and operating system versions.
- Work directly with product owners, project managers, GIS specialists, UX designers, and wildland fire subject matter experts to translate operational requirements into effective mobile solutions.
