AI Trainer (Mathematics and Statistics)

The work

You will help improve AI systems by creating difficult technical tasks and judging whether model answers are correct, well supported, and reproducible. The work combines mathematics, statistics, optimization, programming, and scientific computing.

• Create computational mathematics and statistics tasks for advanced AI models.
• Write clear instructions, prepare reference solutions, and define objective grading criteria.
• Build reproducible environments for technical tasks.
• Review proofs, calculations, programs, statistical results, models, and optimization outputs.
• Find logical errors, invalid assumptions, numerical instability, incorrect statistical methods, and reproducibility problems.
• Validate solutions against objective mathematical and technical standards.

What it pays and takes

This is a remote contractor role with a flexible schedule. The work is open to candidates in the listed eligible countries and requires professional fluency in English.

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