Trilon is building a supercharged, technology-enabled future for our people and partners. The React Native Engineer plays a critical role in that mission by building the mobile application that connects field teams directly to the Digital Platform.

Responsibilities:

• Design, build, and maintain cross-platform mobile applications using React Native
• Develop intuitive user interfaces for field data capture and interaction
• Ensure high performance and responsiveness across a range of mobile devices
• Maintain code quality, testing, and application stability
• Design and implement offline-capable workflows for unreliable connectivity environments
• Build robust data synchronization mechanisms between mobile devices and backend systems
• Handle conflict resolution, data integrity, and retry logic for field-collected data
• Optimize performance for low-bandwidth and intermittent network conditions
• Integrate with device capabilities such as GPS, camera, photo capture, and sensors
• Build workflows for capturing, storing, and transmitting images and geospatial data
• Ensure seamless interaction between native modules and React Native components
• Integrate mobile applications with backend APIs and platform services
• Ensure field data flows cleanly into the data and AI layers of the platform
• Collaborate with backend and AI engineers to support end-to-end workflows
• Maintain consistency with platform architecture and data models
• Partner with the Senior Product Designer to implement consistent, intuitive user experiences
• Work with Product Support Analysts to identify usability issues and friction points
• Incorporate feedback from field users to improve workflows and adoption
• Participate in field engagements or project hackathons to understand real-world usage
• Build and maintain mobile CI/CD pipelines for iOS and Android deployments
• Manage app releases, versioning, and distribution processes
• Monitor application performance and resolve production issues

Requirements:

• 4+ years of experience in mobile application development
• Strong proficiency in React Native and TypeScript
