Mechanical Engineer / Senior Mechanical Engineer, Opto-Mechanics

Xcimer Energy builds on decades of research in Inertial Fusion Energy (IFE), combined with a groundbreaking new laser architecture, to accelerate the deployment of fusion power plants. Our mission is to deploy fusion power plants to meet global decarbonization goals as fast as possible. Xcimer has assembled a world-class team spanning tough tech, fusion science, and advanced manufacturing, with a proven 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. 

 

Every mirror, window, lens, and diagnostic in Xcimer's deep-UV laser system depends on mechanical hardware that holds it precisely, keeps it stable, and lets us align and maintain it. We are looking for mechanical engineers with sound design fundamentals and an interest in opto-mechanics to design, build, and test that hardware. You will work across the full lifecycle: requirements, concept, analysis, drawings, procurement, assembly, alignment, and test. This is a hands-on role where you will spend time in the optics labs, cleanrooms and manufacturing floors. We are hiring at multiple levels, from engineers with a few years of solid design experience who want to deepen their opto-mechanics expertise, to senior engineers who can lead subsystem designs and mentor others.
