The posting

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.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
