About the role

Your deep understanding of physical principles will directly shape how AI reasons through complex problems — from undergraduate fundamentals to graduate-level challenges.

This is a fully remote, flexible contract role. You set your own schedule and contribute as much or as little as your availability allows.

Why Join Us

  • Work on frontier AI projects alongside leading research labs.
  • Fully remote and flexible — work on your schedule, from anywhere.
  • Freelance perks: autonomy, variety, and global collaboration.
  • Meaningful work that directly improves how AI understands and reasons about physics.
  • Potential for ongoing work and contract renewal.

Responsibilities

  • Design rigorous, advanced physics problems spanning mechanics, electromagnetism, thermodynamics, quantum mechanics, and more.
  • Develop clear, step-by-step solutions with precise, logical reasoning.
  • Evaluate AI-generated responses for scientific accuracy, depth, and quality of reasoning.
  • Identify gaps, errors, and weaknesses in AI outputs and provide structured feedback.
  • Collaborate with researchers to build and refine benchmarks across undergraduate to Masters-level physics topics.
  • Work independently and asynchronously on your own schedule.

Required skills

  • Strong analytical and problem-solving skills across multiple advanced physics domains.
  • Able to communicate complex concepts clearly and precisely in writing.
  • Detail-oriented with a commitment to scientific rigor.
  • Self-motivated and comfortable working independently.

Preferred skills

  • Experience with data annotation, content evaluation, or quality assurance.
  • Familiarity with AI or machine learning concepts.
  • Background in tutoring, academic writing, or curriculum development.

Experience and education

  • Currently pursuing or holding a Masters degree (or higher) in Physics, Applied Physics, or a closely related field.
  • No prior AI experience required.
