Physics Expert PhD (AMO / Optical Properties of Materials)
Listed on micro1 as “Physics Expert PhD (AMO / Optical Properties of Materials)”
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.

Is micro1 legit? Our review
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.
