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 (AMO / Optical Properties of Materials)) 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 (AMO / Optical Properties of Materials)

Role Type: Part-Time, Contractor

Location: Fully Remote, Open to candidates worlwide

Schedule: 5-10+ hrs/week. Fully flexible (Can accomodate after hours + weekends if needed)

micro1 is engaging Physics Experts (AMO / Optical Properties of Materials) to contribute their advanced knowledge to a specialized customer project focused on atomic and optical properties. 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

• Provide expert insights on atomic, molecular, and optical (AMO) physics, with an emphasis on the optical properties of materials.

• Review, analyze, and discuss ab initio configuration interaction methods for calculating polarizability in atomic systems.

• Offer guidance and critique on atomic-structure calculations, specifically for Yb-171 and Yb-174 isotopes.

• Identify and differentiate between sigma and pi transitions in relevant atomic spectra, explaining underlying physical principles.

• Participate in adaptive, spoken AI interviews, responding to one question at a time and providing clear, concrete examples from legally shareable research or projects.

Preferred Qualifications

• Advanced degree (Ms,PhD or equivalent experience) in Physics, with a focus on AMO physics or optical properties of materials.

• Proven experience with ab initio quantum chemistry calculations, specifically configuration interaction approaches to polarizability.

• Deep understanding of atomic-structure computation techniques, particularly as applied to ytterbium isotopes (Yb-171 and Yb-174).

• Strong capability to identify and explain sigma vs pi transitions in atomic contexts.

• Demonstrated aptitude for clear, structured written and verbal scientific communication.

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.
