Mechanical Engineering Director (f/m/d)

Focused Energy is building the future of clean energy through laser-driven inertial fusion. Backed by our $240M Series A - the largest fully secured Series A in the global fusion industry we are scaling rapidly across multiple geographies.

Based in Germany and the US, we have brought together the top scientific and engineering minds using proven technologies to unlock fusion power at commercial scale. Focused Energy is working to realize game-changing scientific innovation that promises to deliver a clean, sustainable and abundant source of power globally.

As the Mechanical Engineering Director at Focused Energy, you will design, build, and lead the Mechanical Engineering department, establishing its organizational structure, operating model, engineering standards, and budget. You will oversee end-to-end mechanical capability across key delivery programs, managing peer Chief Mechanical Engineers. Your leadership will ensure that mechanical subsystems are rigorously designed, manufactured, verified, and delivered on schedule to Systems Integration.
