About the role
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.
Sr. GNC Engineer
As a Senior GNC Engineer, you will help design and implement robust control solutions for both endo- and exo-atmospheric flight systems. You’ll work closely with a cross-functional team of mechanical, fluid, and electrical engineers to develop innovative, deployable launch platforms that support Long Wall’s rapid-deployment goals.
This role offers the opportunity to contribute across the full development lifecycle—from 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.
