Mechanical Engineer

About the role

This position focuses on the design and implementation of specialized machinery for testing Starlink satellite components. You will build test systems that validate flight hardware across electrical, mechanical, RF, optical, and propulsion disciplines to ensure mission success. In this role, you will own the full lifecycle of custom test equipment, from initial concept and mechanical design through fabrication, integration, and final acceptance testing. You will be responsible for translating high-level test requirements into detailed mechanical solutions that are robust, repeatable, and scalable for production environments. The position requires a hands-on engineer who actively builds and iterates on hardware while collaborating closely with cross-functional teams. You will troubleshoot test failures, optimize procedures, and document processes to support high-velocity development. Success in this role means ensuring that every test system you deliver enables the team to confidently validate flight hardware against strict performance and reliability standards.
