Xcimer Energy leverages decades of research on Inertial Fusion Energy (IFE) combined with groundbreaking new laser architecture. Our mission is to deploy fusion power plants to meet global decarbonization goals as fast as possible. Xcimer has assembled a team of leaders in tough tech, fusion science, and manufacturing with a track record of rapid execution. Supported by leading investors, Xcimer is uniquely positioned to deliver limitless, clean, fusion power to combat climate change. Join us in powering a better world with inertial fusion! This is a full-time, onsite role based at our headquarters in Denver, CO. As a Pulsed Power Physicist , you will work on the science and engineering of electron-beam cathode systems for Xcimer's pulsed power driven inertial fusion energy program. The core goal is maximizing beam efficiency and energy deposition on target. You will lead cathode development across multiple emitter technologies , design and optimize hibachi foil/anode structures for beam transport, and build complex experimental systems from concept through commissioning. This role carries significant independent scientific responsibility. We want someone who is strong in both theory and experiment and rigorous about documentation.
