Mentor engineers through technical collaboration and example.
What We're Looking For
10 or more years designing and shipping complex hardware systems, with repeated experience taking products from prototype through manufacturing and field deployment.
Mechanical design is your primary discipline, including hands-on CAD, structures, mechanisms, and packaging.
Deep mechanical expertise and sound technical judgment in at least one adjacent area, such as electrical engineering, power electronics, or embedded systems.
Experience leading multidisciplinary hardware integration and designing equipment for demanding real-world environments.
Ability to correlate your own FEA or hand calculations with bench or field test data.
Background as a senior individual contributor or technical lead at a hardware company that shipped products.
Defense, aerospace, robotics, high-performance automotive, maritime, or directed-energy experience is relevant. Experience with ruggedized systems, thermal management, gimbals, qualification standards, or manufacturing setup is valuable.
