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.
The Head of GNC knows not only how to steer vehicles under both endo- and exo- atmospheric conditions, but can also lead teams to push complex problems to reliable, simple, and robust solutions.
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.
Responsibilities
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.
Basic Qualifications
B.S. degree from an accredited university 5+ years of experience in the development of aircraft, missile, spacecraft or similar vehicle GNC system
