Senior Aerospace Engineer (Guidance, Navigation & Control)

Troy 7 Inc.

Regular

PRIMARY FUNCTION

Troy 7, Inc. is seeking an Aerospace Engineer GN&C to support the Jacobs Space Exploration Group (JSEG) Guidance, Navigation, and Control (GN&C) team.  This high-performing group executes challenging tasks to design and integrate GN&C systems for projects ranging from CubeSats, to Mars sample return, to NASA’s Space Launch System (SLS).  In this position, the selected candidate will support the Human Lander System in the Control Systems Design and Analysis branch at NASA’s Marshall Space Flight Center. Successful candidates will serve as a Dynamics, Controls, Modeling, Simulation, and Analysis Engineer. This exciting work will serve as a critical step in sending humans back to the Moon, Mars and beyond.

ESSENTIAL FUNCTIONS:

•    Create, edit, and debug software written in C/C++, Matlab, Simulink, and/or other languages
•    Develop, modify, maintain, and improve software simulations, tools, and scripts
•    Support the design, integration, analysis, and documentation of GN&C products
•    Prepare and present technical reports and/or briefings including visualization of results
•    Create and review engineering and software documentation
