About this role

Experimental Physicist San Leandro, California About Pacific Fusion Pacific Fusion was founded in 2023 with the mission to power the world with abundant, affordable, clean energy. We are rapidly designing and building a pulser-driven inertial fusion system to achieve net facility gain (more fusion energy output than stored energy input). In parallel, we are developing the key components required to build affordable fusion systems. Our plans are ambitious. We have raised over $900M so far from incredible investors, resourcing us to deliver on these plans. We are bringing together the best scientists, engineers, and operators from the fusion community, hard tech industry, and other sectors. We are united by a shared sense of urgency to provide clean power for the world, particularly managing climate change while meeting growing global energy demand. You can read more about us in this letter from our founders . Why This Role Matters Pacific Fusion is seeking an exceptional Experimental Physicist to join our dynamic team and create the path to commercial fusion energy. You will collaborate with engineers and scientists towards our demonstration of ignition and high-gain targets for fusion energy applications. What You'll Do - Run experiments at pulsed-power and other facilities to test aspects of our fusion target design. - Design and implement optical diagnostics for the Demonstration System - Develop analysis methods for experimental data. What You Bring - Experience with optical diagnostics in fusion or other experimental science, especially with interferometry, polarimetry, velocimetry, and similar techniques. - Experience conducting fusion
