How to Break Into Fusion Energy
- Physics or engineering degree — PhD in plasma physics is the gold standard, but MS/BS in nuclear, mechanical, electrical, or materials engineering opens many doors.
- Fission experience transfers — Reactor engineers, health physicists, and nuclear safety professionals are highly valued. Your regulatory and safety culture experience is rare in the startup world.
- National lab connections — PPPL, ORNL, MIT PSFC, GA, and LLNL are the traditional pipelines. Internships and postdocs at these institutions lead directly to private fusion companies.
- Specialized engineering — Cryogenics, high-voltage power electronics, vacuum systems, and superconducting magnet design are specialized skills that fusion companies struggle to hire for.
- Software and controls — Real-time control systems, ML for plasma optimization, and high-throughput data acquisition are growing needs that don't require a physics PhD.
