Principal Guidance, Navigation, and Controls Engineer

About this Role

As a Principal Guidance, Navigation, and Controls Engineer, you will own the full life cycle of GNC development at Varda, from design through to unit, hardware-in-the-loop, on-vehicle functionality, and flight testing. You will perform system analyses, including simulations and Monte Carlo, to satisfy specifications and requirements and to drive system-level architectural and business decisions.

You will contribute to a sophisticated multi-degree of freedom in-house aerospace simulation and test framework and develop and maintain design descriptions and supporting documentation. You'll see end to end execution of the GNC subsystem from initial analysis/design through vehicle integration, mission planning and flight through support of on-orbit and reentry mission operations.

Responsibilities

• ADCS hardware performance specification including sizing of reaction wheels, torque rods, IMU/GPS, and star trackers
• Design and implementation of autonomous satellite attitude control, collision avoidance, orbital rendezvous, burn planning and atmospheric re-entry algorithms
• Perform trajectory design, optimization, and dispersion analysis for the reentry of a space capsule
• Develop 6 degree of freedom vehicle simulation using C++ and Python.
• Running Monte Carlo analysis to characterize performance of new vehicle and mission capabilities
• Integration and testing of GNC sensors, actuators, and software in hardware-in-the-loop environment
• Design and implementation of ground tooling necessary to facilitate fully automated maneuver responsibility and maneuver scheduling decisions
