Summer 2026 Internship - Mechanical Engineering, Pulser

<div class="content-intro"><h2><strong>About Pacific Fusion</strong></h2> <p>Pacific Fusion was founded in 2023 with the mission to power the world with abundant, affordable, clean energy.</p> <p>We are rapidly designing and building a pulsed magnetic 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.</p> <p>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.
