Senior Space Guidance, Navigation, and Controls (GNC) Engineer

Varda Space•El Segundo, CA

2d•Onsite

About The Position

Varda is developing commercial space infrastructure, including in-orbit pharmaceutical processing and reentry capsules. Its W-Series vehicles and associated systems are designed, built, and operated in-house. Varda is headquartered in El Segundo, California, with additional offices in Washington, DC, and Huntsville, Alabama. As a Senior Space Guidance, Navigation, and Controls (GNC) Engineer, you will own the full life cycle of GNC development, from design through unit testing, hardware-in-the-loop testing, on-vehicle functionality, and flight testing. You will perform system analyses, including simulations and Monte Carlo analyses, to meet specifications and requirements and inform system-level architectural and business decisions. You will contribute to Varda’s in-house aerospace simulation and test framework and develop and maintain design descriptions and supporting documentation. The role spans initial analysis and design, vehicle integration, mission planning, flight, and support of on-orbit and reentry operations. The position is on-site in El Segundo, California.

Responsibilities

Specify ADCS hardware performance, including sizing reaction wheels, torque rods, IMU/GPS, and star trackers.
Design and implement autonomous satellite attitude control, collision avoidance, orbital rendezvous, burn planning, and atmospheric reentry algorithms.
Perform trajectory design, optimization, and dispersion analysis for space-capsule reentry.
Develop six-degree-of-freedom vehicle simulations using C++, Python, and MATLAB/Simulink.
Run Monte Carlo analyses to characterize performance of new vehicle and mission capabilities.
Integrate and test GNC sensors, actuators, and software in a hardware-in-the-loop environment.
Design and implement ground tooling to facilitate automated maneuver responsibility and maneuver-scheduling decisions.
Monitor on-orbit system performance and troubleshoot as necessary.
Coordinate with other spacecraft operators, third-party agencies, and the U.S. government.
Contribute to the in-house aerospace simulation and test framework and maintain design descriptions and supporting documentation.
Support GNC execution from initial analysis and design through vehicle integration, mission planning, flight, and on-orbit and reentry mission operations.
