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. As a GNC Engineer, you will help design and implement robust control solutions for both endo- and exo-atmospheric flight systems. Youâll work closely with a cross-functional team of mechanical, fluid, and electrical engineers to develop innovative deployable launch platforms that support Long Wallâs rapid deployment goals. This role offers the opportunity to contribute across the full development lifecycleâfrom modeling and simulation to integration and flight testing. Your work will directly impact every mission and flight, playing a critical part in shaping the future of responsive missile defense systems.
