Collaborating with multidisciplinary teams and leading experts worldwide, your work will directly influence cutting-edge fusion concepts. This is a hands-on opportunity to grow in a dynamic, multinational environment while making a lasting impact on sustainable energy.

• Build, operate and stabilize the frequency-comb front end — set up, run, lock and maintain the comb source in the lab.
• Build, stabilize and characterize cavities — assemble, align, lock and optimize the reference and enhancement cavities.
• Carry out the hands-on lab work of the subsystem — alignment, troubleshooting, measurement and optimization, working independently.
• Work with the multidisciplinary team to integrate your subsystem with the amplification, synthesis and other advanced technologies into the overall system design.
• Utilize common laser diagnostic and nonlinear techniques to measure and analyze ultrafast pulses.
• Document experimental procedures, results, and design recommendations in a structured and traceable manner
• Contribute to the continuous improvement of the laser system, diagnostics and workflows.
• Contribute to laser-operation procedures and safety protocols and ensure compliance with safety standards.

Requirements

• Master's degree or PhD in Physics, Optical Engineering, Laser Engineering, Photonics, or a related field.
• Experimental expertise across ultrafast-laser sources — diode-pumped solid-state, short-pulse and fiber lasers and amplifiers — and their diagnostics.
• Practical experience with optical alignment, laser operation, and laboratory troubleshooting.
• Hands-on experience in optical frequency combs and their stabilization
• Hands-on experience with high-finesse optical cavities — alignment, locking, mode-matching, and finesse/loss optimization
• Practical experience with locking electronics and feedback/servo loops
• Programming and data-analysis skills (e.g. Python) for measurement automation and analysis.
• Strong analytical and problem-solving skills with a structured approach to technical challenges
• A hands-on, self-driven and collaborative working style — you enjoy digging into complex problems with attention to detail in a dynamic, multidisciplinary team.
