Plasma & Fusion Expert

About this role

## 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
