About the Job

Requirements

A Master's degree or PhD in Physics, Optical Engineering, Laser Engineering, Photonics, or a related field is required.
Experimental expertise across ultrafast-laser sources, including diode-pumped solid-state, short-pulse, and fiber lasers and amplifiers, and their diagnostics is required.
Practical experience with optical alignment, laser operation, and laboratory troubleshooting is required.
Hands-on experience in optical frequency combs and their stabilization is required.
Hands-on experience with high-finesse optical cavities, including alignment, locking, mode-matching, and finesse/loss optimization, is required.
Practical experience with locking electronics and feedback/servo loops is required.
Programming and data-analysis skills, such as Python, for measurement automation and analysis are required.
Excellent written and verbal communication skills in English are required.

Responsibilities

Build, operate, and stabilize the frequency-comb front end by setting up, running, locking, and maintaining the comb source in the laboratory.
Build, stabilize, and characterize cavities by assembling, aligning, locking, and optimizing the reference and enhancement cavities.
Carry out hands-on subsystem laboratory work, including alignment, troubleshooting, measurement, and optimization, working independently.
Work with the multidisciplinary team to integrate the subsystem with amplification, synthesis, and other advanced technologies into the overall system design.
Use 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 continuous improvement of the laser system, diagnostics, and workflows.
Contribute to laser-operation procedures and safety protocols, and ensure compliance with safety standards.

About the Company

Marvel Fusion

Pursues laser-driven inertial confinement fusion

Marvel Fusion develops laser-driven fusion energy using non-thermal direct-drive inertial confinement with nanostructured fuel targets. It aims to trigger fusion reactions with low-neutronic fuels like hydrogen-boron, reducing long-lived radioactive waste. The company builds a new high-powered laser facility in collaboration with Colorado State University, housing multiple multi-petawatt lasers to conduct experiments and advance fusion research. Its approach differs from many competitors by applying direct-drive laser for fusion with nanostructured fuels and a focus on hydrogen-boron to minimize waste, supported by a strong academic and private funding network. The goal is to enable a safe, clean, and reliable fusion power plant that helps the world move toward sustainable energy.
