The Head of GNC will define GNC requirements, develop and validate GNC algorithms, oversee system integration, mentor engineers, and address complex technical challenges in missile defense systems.
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.
A Head of GNC knows not only how to steer vehicles under both endo- and exo-atmospheric conditions but can also lead across teams to push complex problems toward reliable, simple, robust solutions. You will have the opportunity to be a key member of a small team of mechanical, fluid, and electrical engineers working to develop innovative deployable launch solutions that enable the rapid deployment of Long Wall launch and test systems. This is a role that contributes to every mission and every flight we fly as we continue to reimagine the future of missile defense systems.

What you need to know about the Los Angeles Tech Scene
Los Angeles is a global leader in entertainment, so it’s no surprise that many of the biggest players in streaming, digital media and game development call the city home. But the city boasts plenty of non-entertainment innovation as well, with tech companies spanning verticals like AI, fintech, e-commerce and biotech. With major universities like Caltech, UCLA, USC and the nearby UC Irvine, the city has a steady supply of top-flight tech and engineering talent — not counting the graduates flocking to Los Angeles from across the world to enjoy its beaches, culture and year-round temperate climate.
Key Facts About Los Angeles Tech
