GNC HIL and Test 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're seeking a GNC HIL and Test Engineer to design, develop, and validate high-fidelity simulations and control algorithms for advanced aerospace systems. This role is ideal for an engineer with strong analytical skills and hands-on experience in guidance, navigation, and control (GNC) who thrives at the intersection of modeling, coding, and flight system development.
Requirements
- Master's or Ph.D. in Aerospace Engineering, Control Systems, Applied Physics, or a related field
- Experience with GNC algorithm development for LEO, GEO, or interplanetary satellite platforms
- Strong understanding of orbital mechanics, rigid body dynamics, and estimation theory
- Demonstrated expertise in Monte Carlo analysis, system identification, and HIL testing
Nice To Haves
- You have deep experience with spacecraft dynamics and control, including 6DOF simulation environments
- You've developed and tested flight control and estimation software for real space/aerial/ground missions
- You're comfortable building estimators like Kalman filters and validating them with data
- You're skilled in MATLAB and C++, and experienced working in version-controlled Linux-based environments
- You have a strong understanding of system modeling, identification, and performance analysis
- You thrive in a fast-paced, hands-on engineering environment and enjoy solving hard technical problems
Responsibilities
- Develop and maintain 6-DOF attitude and orbit simulations, including modeling of spacecraft dynamics, environmental disturbances, and sensor/actuator behavior
- Perform Monte Carlo analyses to evaluate system performance and robustness
- Design and implement control algorithms (PID, LQR, optimal controllers) and state estimators (Kalman filters)
- Conduct Monte Carlo simulations for performance validation, fault injection, and design robustness
- Conduct system identification and model validation from flight or test data
- Write, test, and optimize algorithms in MATLAB and C++
- Collaborate in a Git-based, Linux development environment alongside multidisciplinary teams
