About the Role
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. Design expert-level problems in plasma physics and fusion: magnetic confinement, tokamak and stellarator design, magnetohydrodynamics (MHD), and gyrokinetics
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
You're a Good Fit If You
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
We consider all qualified applicants without regard to legally protected characteristics and provide reasonable accommodations upon request.
Independent contractor engagement, fully remote. Mercor pays weekly via Stripe or Wise.
