The posting

Long Wall Company was created in 2024 to accelerate missile defense technology for the U.S. and our allies. We specialize in ballistic missile defense and are developing Cyclops, a low-cost, mass-producible interceptor. We also produce containerized launchers and offer low-cost targets for threat replication. The future of global security depends on defensive technology that redefines cost, magazine depth, and distribution to deter and defend against evolving threats. Join us.

WHAT WE LOOK FOR

Mission-Driven Problem Solvers – The problems in missile defense demand 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.
