Head of GNC

Long Wall Company was created in 2025 to accelerate missile defense technology for the U.S. and our allies. Building on the RS1 and GS0 launch systems, Long Wall develops containerized, mass-producible missile defense systems and offers rapid, low-cost flight testing. We believe that the future of global security and stability require defensive technology that is lower cost, higher performing, better tested, and more broadly distributed than is possible today. Join us.

What we look for

Mission-Driven Problem Solvers. The aerospace frontier demands ingenuity. We want engineers who approach challenges with curiosity, embrace failure as a learning opportunity, and stay focused on delivering the best solution for the mission.

Total Ownership. We seek engineers who take full responsibility for delivering flight-ready work while recognizing that no one succeeds alone. The best engineers make their teammates better, knowing that complementary skills create force multiplication and drive mission success.

A Head of GNC knows not only how to steer vehicles under both endo and exo-atmospheric conditions but can lead across teams to push complex problems to reliable, simple, robust solutions. You will have the opportunity to be a key member of a small team of mechanical, fluid, and electrical engineers working to develop innovative deployable launch solutions that enable the rapid deployment of Long Wall launch and test systems. This is a role that contributes to every mission and every flight we fly as we continue to reimagine the future of missile defense systems.

• Define, document, and refine GNC requirements to support mission and trajectory objectives.
• Develop, analyze, and validate GNC algorithms, models, and software to ensure system performance.
• Direct test planning, procedure development, and execution for GNC validation.
• Conduct modeling, simulation, and "Hardware in the Loop" (HITL) testing to verify design integrity.
• Oversee system integration, troubleshooting, and resolution of anomalies.
• Define and support avionics and sensor requirements, including IMUs and control actuators (e.g., thrust vector control, throttle valves).
• Perform mission-specific analysis for launches and contribute to business development efforts.
• Mentor junior engineers, providing technical guidance and fostering skill development.
• Take initiative in addressing complex technical challenges and driving innovation in GNC solutions.

•     B.S. degree from an accredited university
•     6 years of experience in the development of aircraft, missile, spacecraft or similar vehicle GNC system

• M.S. or PhD degree from an accredited university
• Demonstrated skills in modeling, simulation, and analysis software such as MATLAB/Simulink and
• Experience in at least one or more high-level programming languages (e.g. C, C , or FORTRAN)
• Experience modeling of interception control systems
• Experience with hypersonic flight regime control systems
• Proficiency in trajectory planning/design and optimization algorithms or tools (e.g. POST2)
• Day of launch or on-orbit systems support including launch limits and loads/GNC capabilities evaluation
• Demonstrated leadership of or within a small project team
• Demonstrated ability to solve complex and difficult technical problems with simple robust solutions
