Senior Gnc Software Engineer
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
