GNC Orbit Controls Engineer

We're looking for a 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 D

• oDevelop open-loop and closed-loop controllers for RAAN and LTAN control, altitude management, station-keeping, and end-of-life disposa
• lImplement and maintain onboard orbit propagators, select and validate integrators, and ensure numerical consistency with ground trut
• hBuild and validate orbit determination pipelines using EKF or UKF with GNSS, and manage navigation readiness and covariance gating for maneuver
• sDesign burns and long-arc trajectories, and optimize delta V and timelines under comm visibility, power and thermal, and operations constraint
• sPlan and execute electric-propulsion long burns, including throttle profile generation, power and duty-cycle scheduling, thermal considerations, ignition and re-ignition logic, progress monitoring, and correction strategie
• sCoordinate burn pointing and wheel momentum strategy with ADC
• SMaintain numerically consistent MATLAB and C++ simulators, create Monte Carlo campaigns, run SIL and HIL tests, and perform post-maneuver reconstructio
