SoftwareEngineer–SpaceSystems

Xona is the navigational intelligence company bringing real-time, centimeter-level certainty to any device, anywhere on Earth. With Pulsar – the world’s most advanced PNT satellite infrastructure in Low Earth Orbit – Xona will offer a future-proof, backwards-compatible global positioning system optimized for absolute precision, superior power, and robust protection. Overview   GNSS (GPS) supports hundreds of billions of dollars in economic activity annually, powering everything from consumer applications to transportation and critical infrastructure. As industries move toward autonomy, the demand for resilient, secure, and high-accuracy Position, Navigation, and Timing (PNT) systems continues to grow beyond what traditional GNSS can provide.   At Xona Space Systems, we are building a next-generation commercial satellite network designed to deliver secure and reliable high-precision navigation and timing services at global scale. Leveraging advancements in satellite technology, software infrastructure, and modern aerospace development practices, our mission is to build the first truly independent high-accuracy alternative to legacy GNSS systems.   As a Software Engineer on the Payload team, you will play a critical role in validating and integrating the software systems powering our satellite platform. You will work across software, hardware, and integration boundaries to ensure reliable communication between payload systems, embedded software, and the satellite bus. This role is highly collaborative and hands-on, involving system-level testing, automation, interface development, and operational reliability across both simulated and hardware-integrated environments.   What You'll Do - Develop and maintain software infrastructure supporting payload and spacecraft system integration. - Design, implement, and validate communication interfaces between payload systems, embedded software, and spacecraft hardware. - Execute full-system software and hardware integration test
