Sr. GNC Software Engineer
Xona Space Systems, Inc, Burlingame, California, United States, 94012
We are seeking a Senior GNC Software 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.
What You'll Do
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
You Might Be a Fit If
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
Requirements
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
To comply with U.S. Government space technology export regulations, applicant must be a U.S. citizen, lawful permanent resident of the United States (i.e. Green Card holder), or other protected individual as defined by 8 U.S.C. 1324b(a)(3).
