Mechanical Engineering Internship/Co-op

Humanity faces two critical challenges: securing reliable energy and aggressively lowering our environmental impact. At Forge, we believe nuclear fission is the key to solving both at once. Today Forge is developing the technology to rapidly scale the deployment of nuclear fission.

As a mechanical engineering intern at Forge, you'll own real hardware on Ember, our 25 MWe nuclear reactor — not a side project. Interns are embedded directly in one of our mechanical teams — components (valves, control-rod drive mechanisms, heat exchangers), fluids (primary and secondary loops, steam generation, heat rejection), or reactor structures (pressure vessel and internals) — and matched to a team based on your interests and experience. You'll design, analyze, build, and test hardware alongside the engineers responsible for it, and see your work carried into a machine meant to power an abundant, clean future. Internship and co-op positions are available for the Spring 2027 and Summer 2027 terms; you'll indicate which term(s) you're available for when you apply.
