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.
Propulsion Engineers at Long Wall ensure the reliable operation of rocket engines and pressurization systems, delivering robust designs that perform seamlessly through all phases of flight. Their scope spans propellant management, pressurization, attitude control, pneumatics, and engine systems. A successful Propulsion Engineer takes full ownership—driving their system from concept to flight, integrating design, analysis, testing, and production into a streamlined, high-performance solution
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.
