ZTO Labs is seeking experts with a Master’s or Ph.D. in Mathematics to create original, graduate-level math questions (e.g., in algebra, analysis, topology, probability).
This is a flexible, remote freelance position. Your work will build a high-quality dataset to challenge and improve advanced AI systems like Gemini 2.5 Pro.
What You’ll Do:
1. Design complex, reasoning-intensive math questions (graduate or advanced undergraduate level) with clear, verifiable answers.
2. Provide detailed, step-by-step solutions and one short, self-contained hint for each question.
3. Include an essential visual component (graph, diagram, etc.) for at least half of your questions.
4. Test your questions against Gemini 2.5 Pro to ensure they are challenging (must fail in at least 4 out of 6 attempts before the hint).
5. Revise questions based on feedback from our audit team.
