About the Role
Join a small defense technology engineering team developing autonomous, field-deployed directed energy systems. As Principal Mechanical Engineer, you will own system-level mechanical architecture and help take complex hardware from prototype through production and deployment.
What You'll Do
-
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.
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.
