Laser Electronics Optical Technician

Focused Energy is a fusion energy startup with the goal of generating unlimited clean energy to responsibly meet future global demand. With the use and commercialization of laser‑induced inertial fusion, a clean and highly efficient power generation technology is coming within reach, suitable to ensure a secure and scalable future energy supply.

We are seeking a Laser Electronics & Optical Technician (LEOT) to support the assembly, integration, testing, and maintenance of advanced laser, optical, and electro‑optical systems used in our fusion energy R&D and prototype platforms. This is a highly hands‑on role, working closely with laser engineers, optical engineers, and systems engineers to bring complex, high‑power laser systems from design into operation.

You’ll play a critical role in ensuring our laser subsystems meet demanding performance, safety, and reliability requirements as we move from experimental setups toward scalable fusion systems.

• Assemble, align, and test advanced laser and optical systems, including beam delivery assemblies

• Perform precision optical alignment and verify laser performance (power, wavelength, beam quality, stability)

• Build, wire, and troubleshoot laser electronics, power supplies, drivers, and control subsystems

• Diagnose and resolve issues across optical, electronic, and electro‑optical systems in R&D and prototype environments

• Execute preventive maintenance, system upgrades, and calibration to meet performance and safety requirements

• Operate safely with high energy lasers, high‑voltage electronics, and controlled lab or cleanroom environments

• Document system configurations, test results, and procedures, and collaborate closely with engineers and scientists

• Must be able to work onsite in our facility in Darmstadt.

• Hands‑on experience in Electronics, Photonics, Optics, Laser Technology, or a related field

• Practical experience assembling, aligning, and testing laser and optical systems

• Strong electronics troubleshooting skills

• Ability to read electrical schematics and optical diagrams

• Experience using precision electrical and optical test equipment

• Experience with fiber‑laser or high‑energy laser systems

• Familiarity with laser safety programs or certification (LSO or equivalent)

• Exposure to CAD drawings, optical design tools, or lab automation systems

• Background in aerospace, defense, semiconductor, medical device, or advanced R&D environments

• Experience working in regulated or safety‑critical lab settings

• Innovative Technology & Mission:
  Be part of a cutting‑edge company working on groundbreaking research in clean energy and scientific discovery.
