Job description

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.

What It Pays And Takes

This is a fully remote, part-time contractor role listed as entry level. A specific degree or number of years of experience is not required when you can demonstrate strong expertise.

• Pay: $60 to $120 per hour equivalent, paid per task that meets the project specifications.
