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 Computational Nonlinear Optical Physicist you will apply your skills to bring inexhaustible, carbon-free, and commercially viable inertial fusion energy through rigorous scientific investigation and innovative engineer. You will work with Xcimer and its scientific partners developing cutting-edge computational modeling tools for the propagation of high intensity beams utilizing stimulated Raman and Brillouin scattering (SRS / SBS), through neutral gas cells and plasmas. You will be an integral part of a design effort to optimize multi-pumped-beam driven amplifiers and pulse compressors, and work with our engineering team to build and test them. These designs are for the staged demonstration of unprecedented, multi-megajoule-scale, inertial fusion energy drivers. We are looking for our scientists to apply their technical expertise, problem solving skills, dedication, passion, and vision to positively impact the future of energy!
