C++MATLABEKFGNSSonboard propagators
Full Job Posting
What You’ll Do
Develop open-loop and closed-loop controllers for 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 orbit determination pipelines using EKF with GNSS
Design burns and long-arc trajectories, and optimize delta V and timelines under comm visibility, power and thermal, and operations constraints
Coordinate burn pointing and wheel momentum strategy with ADCS
Maintain numerically consistent MATLAB and C++ simulators, create Monte Carlo campaigns, run SIL and HIL tests, and perform post-maneuver reconstruction
Required Qualifications
- You are familiar with orbital mechanics and simulation and have had exposure with onboard propagators with perturbation models and integrators on flight targets
- You have GNC software experience in C++ and MATLAB for analysis, modeling, and test-vector generation
- You have supported real maneuvers and can reconcile plan versus truth with post-burn estimation
- You are comfortable at the ADCS and propulsion interface for burn pointing and momentum management
Desired Qualifications
- B.S. or M.S. in Aerospace Engineering, Control Systems, Applied Physics, or a related field
- Familiar with electric propulsion including thrust modeling and calibration, long-burn guidance, duty-cycle planning, and thermal constraints
- Experience with orbit propagation algorithms
- Trajectory design and optimization expertise
- Familiarity with CCSDS ephemeris and attitude formats
