    Job description

    About Pacific Fusion

    Pacific Fusion was founded in 2023 with the mission to power the world with abundant, affordable, clean energy.

    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.
