  • Review problems written by other experts for correctness, clarity and originality.
  • Provide clear written explanations suitable for model training.
  • Follow project guidelines, take part in calibration and review sessions, and incorporate feedback to keep quality consistent.

Requirements

Required Qualifications
  • Master's or PhD in mathematics, or a Bachelor's plus 2+ years of relevant experience.
  • Strong command of at least one core area (analysis, algebra, number theory, probability, combinatorics or geometry).
  • Ability to write clear, rigorous proofs.
  • Excellent written English.
  • Reliable, detail-oriented, and able to work independently and meet deadlines in a remote setting.

Preferred Qualifications

  • Research or mathematical competition experience.
