The Work

You will support AI training by solving difficult scientific, mathematical, and technical problems, then checking whether AI-generated solutions are correct. Your work may focus on a STEM field you know deeply, such as chemistry, biology, mathematics, physics, earth science, geoscience, environmental science, or robotics.

  • Solve complex scientific, mathematical, or technical problems in your area of expertise.
  • Develop rigorous solutions and use Python for calculations or simulations.
  • Review AI-generated answers for factual, mathematical, and scientific correctness.
  • Find incorrect assumptions, reasoning errors, missing constraints, and subtle technical mistakes.
  • Decide whether technical answers meet the relevant scientific or technical standards.
  • Explain errors in reasoning, calculations, or assumptions clearly and precisely.
