Theoretical Physicist - Trajectory Expert - AI Trainer

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.

• 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.

• 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

Around 15 hours per week, roughly one to two tasks per week. Each task averages about 7 hours of writer time.
