Key skills for this role
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.
