Guidance, Navigation, and Control Engineer

MTSI is seeking to a motivated engineer with experience in Guidance, Navigation, and Control (GNC) systems and modeling & simulation. The candidate will support a team delivering modeling, simulation, and analytical products of kinetic weapon system concepts for the Missile Defense Agency. This role offers the opportunity to work on exciting, high-visibility missile system programs and contribute to innovative solutions for national defense. Key Responsibilities: Conduct performance analysis and provide support for the design, integration, and testing of GNC systems for offensive and defensive missile programs. Perform modeling and simulation tasks using 6-DOF simulations to evaluate system behavior, dynamics, and performance under various conditions. Develop, modify, and run 6-DOF models to support analysis of guidance, navigation, and control performance. Collaborate with senior engineers and cross-functional teams to prototype, test, and refine weapon system concepts using legacy 6-DOF simulations in FORTRAN and C++. Develop analytical products, technical reports, and presentations for emerging missile and weapon system concepts supporting DoD programs. Contribute to ongoing missile programs by assisting with requirements analysis, scenario development, and corporate modeling tool improvement. Help maintain and enhance simulation fidelity, including integration of models from different sources and programming languages. Qualifications: US citizenship and an active secret clearance is required Bachelor’s degree in Aerospace Engineering, Mechanical Engineering, Electrical Engineering, Physics, or a related technical field (MS preferred). 3-5 years of hands-on experience in missile systems, aerospace engineering, or related modeling & simulation work. Familiarity with 6-DOF simulation models, including topics such as aerodynamics, guidance algorithms, navigation systems, and basic filtering techniques (e.g., Kalman filters). Some exposure to modeling and simulation tools, including FORTRAN, C++, MATLAB, and Python. Demonstrated ability to conduct system-level and subsystem-level analysis to support requirements development and performance assessment. Strong problem-solving, data analysis, and technical communication skills. #LI-JJ1
