Mathematics Domain Expert at Mercor

Mathematics Domain Expert | $90-140/hr | Remote (US)

Senior mathematicians are being hired to help define how frontier AI models reason about real mathematical research. Your mathematical judgment is the substance of this role: you will review the quality of mathematical reasoning tasks and model outputs, write the problem specifications and reference solutions and proofs that define what "correct" looks like, and design benchmarks that show whether a model is genuinely improving. The role is fully remote.

What the work involves

• Expert review: assess mathematical tasks and model outputs, catching gaps in proofs, unjustified steps, incorrect generalizations, and arguments that read well but would not survive peer review.
• Problem specs and reference solutions: write precise problem statements and rigorous reference solutions and proofs that reflect how research mathematics is actually done.
• Benchmarks: design challenging, research-level problems and evaluation sets in your area of specialization.
• Calibration: work with other researchers and experts in adjacent fields to turn tacit expert judgment into explicit, teachable criteria.

Requirements

• PhD in mathematics, applied mathematics, statistics, operations research, or a closely related field.
• A faculty appointment, principal investigator, staff or senior scientist, or an equivalent senior research role at a university, national laboratory, or research organization.
• Genuine specialization in at least one area, for example analysis and PDE, algebra and number theory, geometry and topology, probability and statistics, or applied mathematics and optimization.
• A strong peer-reviewed publication record. Recognition such as competitive fellowships or awards is a plus.
• Hands-on use of large language models in your work, and the judgment to tell a sound argument from a plausible-sounding wrong one.
• Excellent written communication and the ability to give precise, well-structured feedback.
• Based in the United States.
