Pay: $100–$200/hr

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)

We are 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

1. Provide expert insights on atomic, molecular, and optical (AMO) physics, with an emphasis on the optical properties of materials.
2. Review, analyze, and discuss ab initio configuration interaction methods for calculating polarizability in atomic systems.
3. Offer guidance and critique on atomic-structure calculations, specifically for Yb-171 and Yb-174 isotopes.
4. Identify and differentiate between sigma and pi transitions in relevant atomic spectra, explaining underlying physical principles.
5. 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

1. Advanced degree (Ms,PhD or equivalent experience) in Physics, with a focus on AMO physics or optical properties of materials.
2. Proven experience with ab initio quantum chemistry calculations, specifically configuration interaction approaches to polarizability.
3. Deep understanding of atomic-structure computation techniques, particularly as applied to ytterbium isotopes (Yb-171 and Yb-174).
4. Strong capability to identify and explain sigma vs pi transitions in atomic contexts.
5. Demonstrated aptitude for clear, structured written and verbal scientific communication.
