Principal Mechanical Engineer

• Lead mechanical architecture across the system and integrate it with electrical, power, embedded, and optics disciplines.
• Make technical decisions on challenging engineering problems from concept through production readiness.
• Guide hardware release and production processes in close collaboration with the manufacturing team.
• Identify technical risks early and review designs, analyses, documentation, and release standards.
• Perform hands-on design and analysis when your experience can resolve difficult problems quickly.
• Balance cost, mass, reliability, schedule, and field performance in design and manufacturing decisions.
• Share technical judgment and mentor engineers through direct collaboration and example.
• 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.
• This is an on-site role in San Francisco, California, United States.
