GNC Engineer
About The Position
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. We are seeking a GNC Engineer to join our Guidance, Navigation, and Control (GNC) team. In this role, you will lead the development and integration of flight software that enables autonomous operation of spacecraft. You’ll work closely with GNC engineers to deploy estimators, controllers, and state machines in real-time flight environments, supporting missions from simulation through on-orbit or in-flight operation.
Requirements
- You have deployed estimators and controllers on spacecraft, UAVs, or autonomous systems
- You understand flight software design and integration for GNC applications
- You have experience with state machines and fault management logic in flight-critical systems
- You are detail-oriented in testing and validation
- You work effectively in Git and Linux-based development environments
- You are motivated by building robust and autonomous flight systems
Nice To Haves
- Bachelor’s, Master’s, or PhD in Aerospace, Mechanical, Electrical, or Computer Engineering
- Expertise in Python, C++, and MATLAB
- Hands-on experience with SIL/HIL environments
- Familiarity with model-based development and autocoding workflows (e.g., Simulink + Embedded Coder)
- Experience developing test infrastructure for mission-critical systems
Responsibilities
- Develop and integrate GNC algorithms using model-based development processes
- Implement state machines and FDIR (Fault Detection, Isolation, and Recovery) logic for robust autonomous operations
- Build and maintain GNC software interfaces within the flight software architecture
- Design, implement, and maintain software- and hardware-in-the-loop (SIL/HIL) test campaigns to validate GNC performance and reliability
- Develop unit tests and regression tests to ensure software reliability
- Collaborate across simulation, hardware, and embedded software teams to support end-to-end GNC system validation
