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 a Vacuum Systems Mechanical Engineer, you will lead the design, integration, and operation of vacuum systems for rare-gas/halide (excimer) lasers used in IFE power generation. Your work will begin with prototype systems and continue through the design and demonstration of power-producing IFE reactors. You will ensure that vacuum hardware meets flow and performance requirements throughout the product development lifecycle in a dynamic R&D environment. We are looking for our engineers to apply their technical expertise, problem solving skills, and dedication to quality to positively impact the future of energy!
