Senior GN&C Engineer

Qualis Corporation team is a high performing group executing 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).

We are searching for highly qualified candidates to support the SLS program and/or the Mars Ascent Vehicle in the Control Systems Design and Analysis branch at NASA’s Marshall Space Flight Center. Successful candidates will serve as a Senior 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!

Responsibilities include but are not limited to:

• Serve as the control systems expert representing MSFC in project/program interface meetings with other MSFC Branches, other NASA centers, and contractors developing the systems
• Provide technical leadership, guidance, and mentoring to project/program team members
• Develop, model, simulate, and analyze launch vehicle and spacecraft dynamics (including flexible body, slosh, actuators, etc.), control systems, performance, and stability in both the frequency and time domains with varying levels of fidelity

• Conduct trades studies and/or sensitivity analyses related to launch vehicles and spacecraft
• 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
