Join us in shaping a new era in space and find a career that's built for you

About The Role

Leverage senior engineering experience by joining a Guidance Navigation Control (GN&C) team that designs, develops, and fields advanced control technologies for defense and commercial customers. As a senior engineer, you will collaborate and develop algorithms that will shape the next generation of flight, surface, and space control subsystems, ensuring they meet Lockheed Martin’s rigorous product standards and mission objectives.

What You'll Do

• Perform as a senior GN&C engineer and system integrator through concept, simulation, model based design, hardware in the loop testing, and flight ready prototype delivery.
• Produce detailed algorithmic specifications, implementation requirements, documentation, and verification plans.
• Coordinate closely with perception, mission planning, simulation, and test teams for seamless system integration.
• Translate customer operational needs into technical solutions that leverage cutting edge GN&C capabilities.
• Communicate technical strategies, risks, and progress to senior leadership, program managers, and external partners.

How You’ll Deliver

• End to end development cycles from initial concept through qualification and fielding.
• Develop and validate control algorithms using Matlab/Simulink and generate auto code for target hardware.
• Perform stability analysis, MonteCarlo simulations, and PID/PD controller tuning to meet performance targets.
• Mentor junior engineers, fostering a culture of technical excellence and continuous learning.
• Stay current with GN&C advancements and incorporate state of the art approaches across perception, planning, and control domains.
