## Role Overview & Details

**Role Title:** Physics Expert (PhD / Postdoc)
**Role Type:** Contractor
**Location:** Remote (Worldwide)
**Schedule:** 10–15+ hours a week, Fully Flexible (Can accommodate working after hours/weekends)
**Compensation:** $100 - $200/hr
**Required Skills:** Physics mastery, Written technical communication, Technical problem-solving depth, Mathematical & computational fluency

## Role Description

We are engaging Physics Experts (PhD / Postdoc) to contribute deep scientific knowledge and problem-solving skills to a high-impact customer project. In this role, you'll apply your expertise to help train next-generation AI systems. Your work will shape how models learn, reason, and perform through high-quality, real-world input. No prior experience in AI is required — your domain knowledge is what matters.

## Scope of Work

* Solve advanced physics problems from your specialization, delivering rigorous, well-documented derivations and analyses.
* Produce technically precise, clearly written solutions, detailing all assumptions, approximations, and final results using LaTeX mathematical notation.
* Utilize SymPy, Python, and Jupyter for symbolic or numerical verification and clear computational workflows where relevant.
* Identify and articulate subtleties in problem statements, including special cases, boundary conditions, and dimensional consistency.
* Flag ambiguities in project materials, proposing well-reasoned interpretations and clarifications as needed.
* Iterate on submitted solutions in response to feedback from project reviewers, ensuring corrections are cleanly integrated.
* Uphold rigorous standards in documentation and reproducibility consistent with professional research practice.

## Preferred Qualifications

* PhD in physics or advanced-stage PhD candidacy, with active research experience in a relevant subfield.
* Research expertise in one or more of: High Energy Physics, Mathematical Physics, Biophysics, Statistical Physics, Condensed Matter (including moiré systems, magnetism, PXP/Rydberg), AMO/Quantum Optics, Gravitation, Cosmology, Astrophysics, Quantum Information, or Optical Properties of Materials.
* 2–5 recent representative publications (past ~5 years) in your field, with accessible arXiv or DOI records.
* Proficiency with LaTeX for presenting mathematics, and with SymPy, Python, and Jupyter for computational work; willingness to indicate areas for further support if needed.
* Demonstrated excellence in written technical communication, with a track record of producing clear, precise, and well-argued scientific outputs.
* Strong analytical skills, able to isolate key physical principles and provide nuanced solutions to complex problems.
* Availability to engage with the project consistently over an 8–10 week period (approx. 10 hours/week).
