Balance cost, mass, reliability, schedule, and field performance in design and manufacturing decisions.
Share technical judgment and mentor engineers through direct collaboration and example.
What We're Looking For
At least 10 years of experience designing and shipping complex hardware systems.
Mechanical design as your primary discipline, including recent personal CAD and engineering analysis work.
Repeated experience taking hardware from prototype through manufacturing and field deployment.
Experience designing ruggedized systems for real-world conditions and correlating FEA or hand calculations with test data.
Strong mechanical expertise, with sound technical judgment in electrical engineering, power electronics, or embedded systems.
Experience owning mechanical architecture and integrating multiple engineering disciplines.
A senior individual contributor or technical lead background at a hardware company that has shipped products.
Relevant backgrounds may include defense, aerospace, high-performance automotive, maritime, robotics, or directed energy.
Experience with lasers or high-power systems, thermal management, gimbals or beam directors, military qualification standards, or production line development is useful.
