Sr. CNC Programmer and Machinist

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 require defensive technology that is lower cost, higher performing, better tested, and more broadly distributed than is possible today.

• 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.

We are looking for an experienced CNC programmer and machinist who is excited about manufacturing development and production parts for launch vehicles and defense systems. We seek team members who can think critically when programming and machining to improve hardware designs and manufacturing processes. This role will require specific skill sets with multi‑axis mill programming and machining. Programming will be completed using Mastercam and verified using Vericut.

Parts to be machined on Haas machining centers. Must have the ability and eagerness to both program and machine components. This role will primarily focus on 5th Axis milling work supporting both production and development hardware for various components, specifically launch vehicle engine and space system hardware. In an S5 level role, you will be expected to take projects to completion with a high level of autonomy, mentor junior machinists, and drive shop and process improvements.
