Pay: $80–$160/hr
Role Title: Physics Expert (Condensed Matter / Magnetic Materials)
Role Type: Contractor
Location: Remote
We are engaging Physics Experts (Condensed Matter / Magnetic Materials) to contribute to a leading-edge research opportunity focused on magnetic space groups, neutron scattering, BNS notation, and the physical signatures of magnetic order. 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
- Analyze and interpret magnetic structure factors, utilizing propagation-vector methodologies and advanced symmetry concepts in condensed matter physics.




- Identify and classify magnetic phases (AFM, FM, and related types) using both theoretical and experimental data, including neutron diffraction results.
- Curate and validate magnetic space group assignments with reference to established datasets such as MAGNDATA, ensuring robust correlation with BNS notation conventions.
- Evaluate birefringence and magneto-optic Kerr effect (MOKE) signatures for selected materials, connecting optical phenomena to underlying magnetic structure.

Preferred Qualifications
- Advanced academic background (PhD or equivalent research experience) in condensed matter physics, with a specialization in magnetism or related fields.
- Demonstrated proficiency in magnetic structure factor calculations, propagation-vector analysis, and symmetry-based phase identification.
- Direct experience classifying magnetic space groups, with hands-on familiarity with MAGNDATA and BNS notation.
- Strong knowledge
