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.

- Drive design for manufacturability (DFM) and design for assembly (DFA), partnering closely with technicians, machinists, and suppliers to deliver hardware on cost and schedule
- Write and execute test procedures (component qualification, acceptance, integrated checkouts); analyze data and iterate designs based on results
- Author and present technical documentation—requirements, ICDs, design reviews, test plans, and reports—to internal and external stakeholders
- Mentor junior engineers, lead design reviews, and serve as the go-to technical resource on your product line
Requirements
- Bachelor’s degree in mechanical, Aerospace, or related engineering discipline from an accredited university AND 8 years of related industry experience; • OR Master’s degree AND 6 years of related experience;
- OR Ph.D. AND 3 years of related experience
- Experience taking aerospace or defense hardware from prototype through flight qualification and field support
- Ability to develop scripts in Python or MATLAB for automation and analysis
- Hands-on experience with assembly, integration, and test of flight hardware in a fast-paced lab environment
- Experience designing for containerization, rate production, or other mass-producibility constraints
- Familiarity with U.S. missile defense, launch, or hypersonics programs
- Demonstrated ability to mentor junior engineers and lead technical design reviews
- Ability to sit or stand for extended periods of time
- Ability to use a computer to complete assignments
- Ability to communicate with individuals and groups in person, by phone and telepresence
