**New Role: Research Physics Expert — Remote | Flexible | Part-Time | $80–$140/hr | Worldwide** Train AI models for the CrypPt challenge | to fit around your day-job
Mercor are seeking seeking expert physics researchers to author and verify golden reference solutions for the CritPt benchmark (arXiv:2509.26574v3) — a frontier research-level physics benchmark. Participants will solve CritPt research-level problems end-to-end, audit solutions from other experts, or adjudicate between parallel solution attempts, producing 100%-human-verified reference data used to evaluate large language models on frontier physics reasoning.
**What the work involves**
- Solve frontier-level physics problems end-to-end with full derivations, code, and peer-reviewed references
- Decompose problems into checkpoint sub-problems and author Python answer templates with auto-grading functions
- Audit submitted solutions for correctness, scope, and method soundness; deliver structured feedback across iterations
- Adjudicate between parallel solver attempts to determine the golden reference solution
- All work remote and asynchronous — typically 10 hrs/week
**Who this suits**
- Solver role: PhD or postdoc in a relevant subfield (senior PhD student minimum)
- Auditor role: Postdoc or junior professor (PhD minimum)
- Adjudicator role: Full professor or industry research PI (senior postdoc or junior professor minimum)
- Subfields covered: HEP & Mathematical Physics, Biophysics, Statistical Physics, Condensed Matter, AMO, Gravitation, Cosmology, Astrophysics, Quantum Information, Optical/Magnetic Materials, Measurement in QM
- Working proficiency with LaTeX, Python, Jupyter, and SymPy required
- No H-1B or STEM OPT candidates
**What's available**
- Research Physics Expert — $80–$140/hr (set by role and demonstrated expertise)
