About The Team

Our Guidance, Navigation, and Control (GNC) group challenges convention and drives innovation to transform how missions are executed. We design and develop the hardware, algorithms, and software that enable precision control of complex systems in demanding, zero-gravity environments. Through digital modernization, advanced analytics, and emerging technologies, we push the boundaries of national security and defense.

While much of the work on this program remains classified, you will play a key role in developing end-to-end solutions that deliver tangible impact. You’ll collaborate with some of the brightest minds in engineering to design, integrate, and deploy pioneering capabilities that shape the future of our mission.

About The Role

In this role, you will contribute to the design, analysis, and testing of guidance, navigation, and control systems that enable spacecraft to operate in complex space environments. You’ll collaborate closely with multidisciplinary teams to develop robust, flight‑proven GN&C solutions and ensure mission success through rigorous simulation and validation.

What You Will Be Doing

• Perform spacecraft controls design, analysis, simulation, and testing activities.
• Develop and validate GN&C algorithms and flight software.
• Utilize simulation and programming tools (e.g., MATLAB/Simulink, C++, Python).
• Apply Kalman Filtering and Attitude Determination techniques to mission design.
• Support hardware integration and mission operations in a dynamic, team‑oriented environment.

Applicants will generally possess a minimum of 3+ years of related experience and may have a post‑secondary degree or training in a related discipline.

Successful completion of customer required Polygraph Examination with favorable results is required for long term employment on this program

The information below reflects the standard job description for this position:

Designs, develops, implements and tests algorithms to perform guidance, navigation and control of aircraft, spacecraft, launch vehicles and upper stages during powered and coast phases of flight, earth orbit, interplanetary cruise and orbital insertion, as well as during staging events. Navigation functions include the statistical processing of measured data points and their substitution into algorithms simulating physical reality. Guidance functions include the formulation of specific equations and control laws to achieve a desired position in space. Control design and analyses processes consist of the development of the control requirements for aircraft, launch vehicles and/or spacecraft.

Basic Qualifications

Skill Requirements

• Strong experience in spacecraft controls design, analysis, simulation, and test.
• Experience with simulation and programming tools such as MATLAB/Simulink, C++, Python.
• Experience with Kalman Filtering and Attitude Determination.
