Space is a critical domain, connecting our technologies, our security, and our humanity. While others view space as a destination, we see it as a realm of possibilities, where we can do more — we can innovate, invest, inspire, and integrate our capabilities to transform the future. At Lockheed Martin Space, we aim to harness the full potential of space to cultivate innovation, reduce costs, and push the boundaries of what technology can achieve.

We’re creating future-ready solutions, focusing on resiliency and urgency through our 21st Century Security vision. We’re erasing boundaries and forming partnerships across industries and around the world. We’re advancing spacecraft and the workforce to fuel the next generation. And we’re reimagining how space can connect us, ensuring security and prosperity.

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.

• 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.

• 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, Monte Carlo 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.

Successful applicants generally possess 1+ years of related experience and may have a post-secondary degree or training in a related discipline.

• Experience modeling and controlling 3 phase motor systems.
• Hands on work with FPGAs or microcontrollers, including auto code generation from Simulink.
• Leadership experience guiding small engineering teams.
• Design or test experience with missile or space segment subsystems.
• Familiarity with change control processes.
