Sr. GNC Orbit Controls Engineer

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 looking for a Sr. GNC Orbit Controls Engineer to design and implement the algorithms and onboard software that handle orbit determination, guidance, maneuver execution, and post-maneuver analysis to deliver safe, efficient, and highly automated station-keeping and disposal. We’re building the software that keeps our spacecraft exactly where they need to be.

What You’ll Do

• Develop open-loop and closed-loop controllers for RAAN and LTAN control, altitude management, station-keeping, and end-of-life disposal

• Implement and maintain onboard orbit propagators, select and validate integrators, and ensure numerical consistency with ground truth

• Build and validate orbit determination pipelines using <
