Pulsed Power Physicist Engineer

Xcimer Energy, Inc., Denver, CO, United StatesEmployer Description

XCIMER Energy Company is a startup pursuing baseload energy production from inertial fusion.  We are using the same fundamental physics recently proven by the NIF (National Ignition Facility), made economically viable by XCIMER’s novel, low-cost laser architecture. XCIMER was founded in 2021 by a team of experts in high-energy laser systems, nuclear physics, and fusion engineering, and is backed by leading clean energy and deep-tech investors. XCIMER’s comprehensive, integrated design for a power plant has been analyzed and reviewed by independent experts and offers the most assured path to put fusion energy on the grid within 10 years. XCIMER is currently finalizing plans for construction of a prototype, multi-kJ laser facility to demonstrate critical aspects of the XCIMER laser architecture.

Job Description

Xcimer is looking for a pulsed power physicist/engineer, 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.
