Your work will directly enable first responders, emergency management teams, and defense personnel to maintain situational awareness and communicate effectively during life-saving operations—even in environments with limited or no connectivity. You'll craft robust user interfaces for handheld radios and situational awareness software, working at the intersection of application development and low- level hardware integration. From day one, you'll own the full development lifecycle: building Android UI components for critical field applications, integrating with peripheral devices like handheld radios, USB hardware, and network adapters, writing and maintaining FFI bindings between Kotlin/Java and native C/C++ code, authoring comprehensive automated tests, and streamlining CI/CD pipelines for reliable releases. You'll work directly with public sector customers and field personnel to diagnose integration issues, conduct field testing to ensure applications perform flawlessly under real-world emergency conditions, and iterate quickly on feedback from those whose lives depend on your work. You'll join a dedicated US-based team that values trust, clear communication, and continuous improvement. In our async-first culture, your written design docs and code reviews carry as much weight as face-to-face meetings, and occasional field deployments and offsite gatherings bring us together to test our solutions in real-world scenarios.
