Laser Engineer

Your Role

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.

What You'll Do

• Own the hands-on setup, alignment, and execution of assigned FELA laser experiments including setting up the laser front end, running two-dimensional SSD, frequency tripling, FM-AM, and main amplifier characterization experiments.
• Lead bench-level troubleshooting.
• Drive the day-to-day experimental schedule, ensuring setups are ready and experiments run on time against the FELA build-out plan.
• Ensure all laser safety protocols and lab safety standards are followed without exception in a Class 3B/4 laser environment.
• Build and maintain organized, well-documented lab records covering equipment status, alignment logs, and experimental data.
• Improve experimental setups and procedures over time, identifying and proposing refinements based on hands-on experience.
• Partner with laser scientists on joint experimental sessions, providing reliable bench execution that enables scientific progress.
• Help the FELA facility scale its experimental program by building repeatable, well-documented setups that others can follow.

Who You Are

• Hands-on experience with fiber and free-space laser systems, nonlinear optics (frequency conversion, beam smoothing), laser beam characterization, and optical alignment and diagnostics.
• Comfortable working independently on bench-level setup, alignment, and troubleshooting, and know when to upscale a genuinely stuck problem rather than push through it.
• A systematic, methodical approach to experimental work, with strong lab notebook and data documentation habits.
• Working knowledge of laser safety standards (ANSI Z136) and experience operating safely in Class 3B/4 laser environments.
• Clear, proactive communicator — you flag issues early and keep your team members informed on progress and blockers.
• Take ownership of your work end-to-end and set a high bar for safety discipline and lab practice as the team grows around you.

Preferred

• Familiarity with laser modeling software (e.g. Miro, Zemax) and CAD tools (e.g. Inventor)
