Principal Guidance, Navigation, and Controls Engineer

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.

• ◆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
• ◆Monitoring on-orbit system performance; troubleshooting where necessary
• ◆Coordination with other spacecraft operators, 3rd party agencies, and the US government

Varda, like all employers, must ensure that its employees working in the United States are lawfully authorized to work in the U.S. Additionally, our employees are exposed to and have access to certain export-controlled items. Because our employees are provided access to export-controlled items, our policy is to only hire “U.S. persons” who are permitted to have access to our technology without an export license.

“US person” means: U.S. citizen, U.S. lawful permanent resident, or protected individual as defined by 8 U.S.C. 1324b(a)(3) (i.e., individual admitted to the U.S. as a refugee or granted asylum).
