Guidance, Navigation, and Control (GNC) Engineer - Navigation

What You'll Do

As a GNC Engineer, you will focus on developing the navigation and state-estimation capabilities that enable precise and autonomous spacecraft operations. You will work on spacecraft state estimation, sensor fusion, GNSS/INS navigation, attitude and orbit determination, and relative navigation for rendezvous and proximity operations.

Responsibilities

• Design, implement, test, and validate spacecraft navigation and state-estimation algorithms
• Develop and tune Extended Kalman Filters (EKF) and other state-estimation algorithms for spacecraft applications
• Support navigation algorithm development for rendezvous, proximity operations, and autonomous spacecraft operations
• Develop high-fidelity sensor models including measurement noise, bias, scale factor, misalignment, latency, and other error sources
• Analyze navigation performance and troubleshoot estimation issues using simulation and test data
• Perform navigation error analysis, observability analysis, covariance analysis, Monte Carlo simulations, and performance assessment
• Support the implementation and integration of navigation algorithms on flight hardware and participate in SIL, PIL, and HIL testing and validation activities
• Collaborate with GNC, flight software, systems, and mission design teams to integrate navigation solutions into the spacecraft

What We Look for

Minimum Requirements

• Bachelor's or Master's degree in Aerospace, Electronics, Control Systems, or a related engineering discipline
• 1+ years of experience in spacecraft navigation, state estimation, GNSS/INS, robotics, or a related field
• Experience with MATLAB, Simulink, C/C++, and/or Python
• Strong understanding of estimation theory, Kalman filtering, state-space models, probability, and sensor fusion
• Understanding of spacecraft navigation sensors such as GNSS, IMU, star trackers, and optical navigation sensors
• Experience with numerical analysis, simulation, and algorithm development
• You thrive in fast-paced, dynamic environments, adapt quickly, and enjoy solving hard problems
