Principle Power Electronics Engineer

Overview

Long Wall Company was created in 2025 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.

Join us.

Mission-Driven Problem Solvers. The aerospace frontier demands 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.

As a Power Electronics Engineer, you will lead the development, design, build, and commissioning of power conversion systems at Long Wall to support product tests, operations, and launches. 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 individual will be responsible for electrical design, test, and integration, from concept to production, while ensuring alignment with strategic business goals. The engineer could also be involved in managing key vendor relationships and ensuring performance and reliability in our cutting-edge launch technologies. 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.
