Plasma & Fusion Expert

Role Overview

Mercor is partnering with a leading AI lab to strengthen expert-level scientific reasoning in frontier models. We are hiring plasma and fusion physics experts to author and review challenging problems in plasma physics and magnetic-confinement fusion and to evaluate AI-generated solutions for correctness and rigor.

What You'll Do

• Design expert-level problems in plasma physics and fusion: magnetic confinement, tokamak and stellarator design, magnetohydrodynamics (MHD), and gyrokinetics
• Review problems authored by peers for clarity, genuine difficulty, and ground-truth correctness
• Evaluate and compare AI model outputs, delivering Accept / Revise / Reject verdicts with detailed written rationale

Ideal Qualifications

• PhD or equivalent research experience in plasma physics, fusion energy, nuclear engineering, or a related field
• Hands-on experience with magnetic-confinement fusion (tokamak or stellarator), MHD, plasma transport, or gyrokinetic simulation
• Strong scientific writing and meticulous attention to detail
