Mathematician, PhD
up to $120/hr
About this role, in Alignerr's words
What if the mathematical expertise you spent years developing could directly shape how AI reasons, proves, and solves problems for millions of people worldwide? We're looking for PhD-level mathematicians to evaluate and improve the mathematical capabilities of cutting-edge AI systems — ensuring they meet the highest standards of rigor, accuracy, and logical soundness.
What you'll do
- Develop, review, and refine advanced mathematical problems and questions — spanning areas such as causal inference, experimental design, proof construction, and abstract theory
- Evaluate AI-generated mathematical reasoning, identifying errors in logic, methodology, and computation
- Annotate and categorize mathematical expressions, proofs, equations, and word problems to build high-quality training datasets
Show all 6 itemsHide the other 3 in What you'll do
- Map relationships between mathematical concepts to help AI models understand the deep structure of mathematics
- Contribute to comprehensive training datasets that span a wide range of mathematical domains and difficulty levels
- Provide expert feedback that directly improves AI model accuracy and reasoning quality
Candidate background
Who You Are
- You hold a PhD in mathematics or a closely related field, with demonstrated expertise in research, teaching, or advanced problem-solving
