Papaya Mathematics - AI Trainer (Remote, Freelance)
USD /hour
Overview
Responsibilities [About the Role] We are looking for experienced mathematics professionals to help train and evaluate advanced AI models so they can reason like real-world math experts. In this role, you’ll use your mathematical expertise to design challenging problems, review AI-generated solutions, and define clear evaluation standards across a range of mathematical domains. This is a flexible, remote freelance role that can be done alongside your existing research, teaching, or professional commitments. [What You’ll Do] As a Mathematics Expert – AI Trainer, you will: • Evaluate AI-generated answers to math questions for correctness, logical rigor, and clarity of reasoning. • Design realistic math problems, prompts, and multi-step exercises (e.g., algebra, calculus, probability, discrete math, and applied modeling). • Create scoring rubrics and structured evaluation guidelines to assess model performance in your area of expertise. • Verify and, when necessary, correct step-by-step reasoning, notation, and final answers. • Provide high-quality written feedback to help improve the problem-solving strategies and mathematical communication of AI models. • Collaborate with AI teams to refine tasks, datasets, and evaluation methods over time.
Qualifications Bachelor’s, Master’s, or PhD in Mathematics, Applied Mathematics, Statistics, or a closely related quantitative field. At least 2–3 years of research, teaching, or professional experience in one or more of the following areas: • Algebra and Geometry (including pre-algebra, algebra, intermediate algebra, Euclidean/analytic geometry) • Calculus and Analysis (single-variable, multivariable, real/complex analysis) • Probability and Statistics • Discrete Mathematics (combinatorics, graph theory, number theory) • Applied Mathematics or Mathematical Modeling Strong grasp of core mathematical skills such as: • Rigorous proof-writing and logical reasoning • Step-by-step problem solving and error checking • Translating real-world scenarios into mathematical models • Using precise notation and clear structure in solutions Excellent written English, with the ability to explain complex mathematical ideas clearly and precisely to a non-expert audience when needed.
