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

Our Guidance, Navigation, and Control (GN&C) 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.

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.

Successful 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.

Desired skills:

• Active TS/SCI clearance with CI Poly.
• Experience with flight software development and autocode to C++.
• Jitter analysis experience (highly desired).
• Familiarity with a GN&C hardware suite for space applications.
• Mission operations experience.
• Ability to work in a fast-paced, dynamic, collaborative team environment.
• Strong communication skills with the ability to articulate complex technical issues to peers, management, subcontractors, and customers.
