What this actually is

You design problems that stump current AI models, evaluate AI reasoning against the correct answer, write rubrics, and provide expert feedback. Often the highest-paid category because the expertise pool is small. The platform title (Physics Expert (PhD / Postdoc)) reflects the rate band and the expertise required, not the day-to-day work.

Can you do this on your visa?

F-2 / F-4 / F-5 / F-6: open. E-1 to E-7: needs concurrent-employment permit. D-2 / D-4 students: S-3 permit, 20 hr/week cap. D-10 / D-8: case by case.

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)

micro1 is 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).

A real US company that pays experts in USD through Deel twice a month. The hard part is getting from the Zara AI interview to paid work. Pay, who can join, and how Korean visa and tax rules apply.
