Laser Technician (f/m/d)

Job description

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. Your Role Focused Energy's Power Amplifier development depends on laser systems that are built, aligned, and maintained to exacting standards. As our Laser Technician, you’ll be performing hands-on technical work, ensuring our laser and optical systems are assembled correctly, perform reliably, and stay in operational condition throughout the R&D cycle. Based onsite at our Darmstadt facility, you'll work alongside laser engineers, optical designers, and electronics specialists as a core member of the Laser team. You'll be a person who keeps the lab running: without this capability in-house, development velocity slows and engineers get pulled away from higher-level design work. You'll perform the hands-on lifecycle of our laser system hardware, from assembly and alignment through testing, maintenance, and documentation. What You'll Do Perform assembly, alignment, and testing of laser amplifier systems and beam delivery assemblies to specification. Lead preventive maintenance, calibration, and system upgrades to keep laser infrastructure in operational condition. Drive fault diagnosis across optical, electro-optical, and basic electronic subsystems, resolving issues or escalating with clear documentation. Ensure all work with high-energy lasers, high-voltage electronics, and controlled lab environments meets applicable safety standards. Build and wire laser-related electronics, including power supplies, drivers, and control subsystems. Improve system documentation — configurations, test results, and procedures — so engineers and future technicians can rely on it. Partner with laser engineers and scientists to support development, integration, and troubleshooting across the R&D program. Enable rapid development cycles by maintaining lab readiness and responding quickly when systems need attention. Who You…
