PhD Physicist — Frontier Reasoning Trajectory Writer
MercorDescription
PhD Physicist — Frontier Reasoning Trajectory Writer
What you'll do
Produce "golden trajectories" for hard physics problems: complete, step-by-step solution walkthroughs where every reasoning step is sound, the final answer is correct, and the work is organized around a sensible upfront plan. You'll work in Studio, iterate with a frontier LLM to draft and refine the reasoning, and produce trajectories that are clean enough to use as training data. The problems are provably hard — we screen them by running a frontier LLM on each problem five times and requiring it to fail at least once.
Domain focus
We need physicists with a theoretical or computational specialization in one of: - Astrophysics (theory / numerical) - Condensed matter (theory) - Quantum physics / quantum information - Particle / high-energy physics
We are not looking for experimentalists, software engineers, or data scientists without a physics PhD background.
Requirements
- PhD in physics, or in the final 1-2 years of a PhD program, from a credible research institution
- Daily-driver fluency in LaTeX (for derivations) and Python (for numerical sanity checks and plotting)
- Comfort with iterative LLM workflows — willing to nudge models with hints, identify reasoning errors, and shape an exploration into a clean trajectory
- Detail-oriented; comfortable producing publication-grade derivations
Time commitment
Around 15 hours per week, roughly one to two tasks per week. Each task averages about 7 hours of writer time.
How to apply
Submit your application and complete the short technical assessment. Strong applicants will be invited to a follow-up interview.
