Overview:

The Sr Aerospace Navigation Lead Engineer assists a team of navigation engineers across NASA centers that perform independent navigation analysis and simulation for the Human Lander System (HLS) program to assess and communicate risk to the HLS Chief Engineer and HLS commercial partners. This position will require demonstrated strong leadership and communications skills as well as strong technical background, including deep space navigation and orbit determination. The engineer will assist a navigation team that performs high fidelity analysis of the HLS navigation architecture to assess mission risk.

Description:

The Amentum Space Exploration Division (ASED) Guidance, Navigation, and Control (GN&C) team is a high performing group executing challenging tasks to design and integrate GN&C systems for NASA projects ranging from NASA’s Space Launch System(SLS) to NASA’s Human Lander System. We are searching for highly qualified candidates to support NASA’s Flight Dynamics Team in the Guidance, Navigation, & Mission Analysis branch at NASA’s Marshall Space Flight Center. This exciting work will serve as a critical step in sending humans back to the Moon, Mars and beyond!
