Job Description

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!

As an Experimental Physicist, you will lead the design, execution, and interpretation of experiments central to Xcimer’s Vulcan fusion program which aims to demonstrate wall plug breakeven. This individual will translate the physics basis and risk retirement plan into executable experiments, own diagnostic requirements, and develop Vulcan test plans that validate facility and subsystem readiness for ignition physics.

As the first experimentalist in the program, this role bridges physics, engineering, and systems integration. This physicist will ensure that Vulcan’s design, diagnostics, and experimental capabilities align directly with the needs of the Fusion Pilot Plant physics basis. We are looking for our scientists to apply their leadership, technical expertise, curiosity, problem solving skills, and dedication to quality to positively impact the future of energy!
