Job description

Long Wall Company was created in 2024 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 requires 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 Team members 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 staff and engineers who take full responsibility for contributing to and delivering flight‑ready work while recognizing that no one succeeds alone. The best engineers, corporate professionals, and technicians make their teammates better. Knowing that complementary skills create force multiplication and drive mission success.
