ABOUT THE ROLE
Join a small defense technology team developing autonomous directed-energy systems for counter-drone applications. As Principal Mechanical Engineer, you will own system-wide mechanical architecture and help take complex hardware from prototype through production and field deployment.
WHAT YOU'LL DO
- Lead mechanical architecture and integration across electrical, power, embedded, and optics subsystems.
- Make technical decisions on challenging hardware problems from concept through production readiness.
- Guide hardware release and production processes in partnership with manufacturing teams.
- Review designs, calculations, and test results to identify risks early and maintain high engineering standards.
- Personally execute mechanical design work when your experience can resolve a problem quickly.
- Balance cost, mass, reliability, schedule, and field performance in design and manufacturing decisions.
- Mentor engineers through hands-on technical leadership and design reviews.
WHAT WE'RE LOOKING FOR
- 10 or more years designing and shipping complex hardware systems, including multiple transitions from prototype through manufacturing and deployment.
- Mechanical engineering is your primary discipline, with recent hands-on experience in CAD, structures, mechanisms, and packaging.
- Deep mechanical expertise and sound judgment in at least one additional area, such as electrical engineering, power electronics, or embedded systems.
- Experience leading full-system hardware integration and designing equipment for demanding real-world environments.
- Ability to correlate FEA or hand calculations with bench or field test data.
- Background as a senior individual contributor or technical lead at a hardware organization that shipped products.
- Experience in defense hardware, aerospace, robotics, high-performance automotive, maritime, or a related field is valuable. Directed energy, laser or high-power systems, thermal management, ruggedized equipment, and manufacturing scale-up experience are also relevant.
