Physics Research Expert (Solver)

Contractor · Remote · 10 openings

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.

Key Responsibilities

  • Contribute deep domain expertise in your specialized physics subfield, providing authentic, up-to-date insights for AI training initiatives.
  • Formulate, solve, and document advanced mathematical physics problems using rigorous methodologies.
  • Develop and validate computational models, simulations, and analytical solutions leveraging Python, SymPy, and Jupyter environments.
  • Produce high-quality, publication-level written explanations and derivations with clear, structured reasoning.
  • Clearly communicate complex concepts and solutions through both written and verbal exchanges with project coordinators and the technical AI team.
  • Work independently to navigate and resolve challenging, novel research problems aligned with the assigned subfield.
  • Leverage your experience to review, critique, and improve problem solutions, ensuring accuracy and clarity for AI training.

Required Skills & Qualifications

  • PhD (or senior PhD student) in physics with active, ongoing research in one or more targeted subfields: High Energy/Mathematical Physics, Biophysics/Statistical Physics, Condensed Matter, AMO/Quantum Optics, Gravitation/Cosmology/Astrophysics, Quantum Information, or Optical properties of materials.
  • 2–5 representative publications (last 5 years) in the relevant subfield, with available arXiv/DOI links.
  • Expertise in mathematical modeling, derivations, and system proofs at a publication-worthy standard.
  • Proficient in LaTeX, Python, SymPy, and Jupyter (flag any skill gaps).
  • Exceptional written and verbal communication skills—clarity, accuracy, and the ability to explain intricate concepts are essential.
  • Demonstrated ability to work independently and execute research tasks with minimal supervision.
  • Must be based in the US, UK, or Canada (rare exceptions for truly exceptional candidates).

Preferred Qualifications

  • Experience in AI training or interdisciplinary computational research projects.
  • Recognition as a thought leader, contributor, or reviewer in your physics subfield.
