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 seeks accomplished scientists and engineers with expertise across the spectrum of fusion energy disciplines. This role is for professionals from U.S. national laboratories interested in pursuing an Outside Business Activity (OBA) in fusion energy under the expanded opportunities provided by Section 10720 of the CHIPS and Science Act. Under the new CHIPS Act framework, national laboratory staff can directly participate in advancing fusion energy science and technology as a Pacific Fusion employee outside of their day job at the lab.
