Principal Mechanical Design Engineer - Mechanical Systems

Shield AI is seeking a Principal Mechanical Design Engineer with deep expertise in mechanism design to support the development of our next-generation autonomous UAV platform. In this high-ownership role, you will lead the architecture, design, and development of precision mechanical systems and actuation mechanisms that are critical to mission success. You will work closely with cross-functional teams to create rugged, lightweight, and manufacturable mechanisms-ranging from landing gear to deployable payload systems-while delivering high performance in dynamic and harsh environments. What you'll do: Design complex electro-mechanical mechanisms for autonomous aircraft. Own the full design process: concept, CAD, tolerance analysis, material selection, and drawing release. Prototype, test, and iterate mechanism designs for functionality and reliability. Collaborate with electrical, avionics, flight controls, and propulsion teams.
