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 Pulsed Power Physicist, you will be responsible for electrical design, hardware procurement support, overseeing of assembly, testing and operation of large pulsed power systems that power rare-gas/halide (excimer) lasers; initially for Xcimer prototype systems, and continuing through the design and demonstration of a power-producing IFE reactor. We are looking for physicists and engineers to apply their technical expertise, problem solving skills, and dedication to quality to positively impact the future of energy!


  • Perform electrical and magnetic field analysis for pulsed power and high voltage circuit elements and systems, using 2D and 3D electromagnetic finite element analysis (EM FEA) software, such as QuickField, Dassault CST Suite, or other, for static as well as transient responses.
  • Perform circuit simulations of transient circuits using lumped element codes such as SPICE and its derivatives and CASTLE (NRL), as well as some transmission line analysis using codes such as BERTHA (NRL) and SCREAMER (SNLA), as necessary
  • Communicate and interact with mechanical, laser and optical engineering members of the design team
  • Follow the design of the kJ-scale (optical) Phoenix laser system through Preliminary and Final Designs, and support procurement
  • Oversee and assist assembly by a team of interdisciplinary technicians
  • Support shake-down, testing and operation of pulsed power system(s) in support of laser development
  • Support and perform data acquisition and analysis
  • Continue above roles and responsibilities to participate in subsequent amplifier up-scaling leading to that which is needed for a power-producing IFE reactor
  • Participate in concept studies supporting the use of these lasers in a power-producing IFE reactor, and other applications


  • Bachelor’s or Advanced Degree in Pulsed Power Engineering, Physics, and/or Electrical Engineering
  • 5+ years experience working on Pulsed Power
  • A willingness to learn from senior technical staff of 40+ years of experience
  • Experience in computer simulation as an analysis and design tool
  • Deep knowledge of transmission line theory as applied to transient circuits
  • Working experience in a high voltage laboratory
  • Must be authorized to work in the United States for any employer


  • PhD in Pulsed Power Engineering or Physics
