About These Roles

Our freelance math jobs span three primary tracks: education, AI/ML data operations, and quantitative content creation. In education, you’ll tutor learners, design assessments, and create step-by-step solutions. In AI/ML data labeling, you’ll perform RLHF (Reinforcement Learning from Human Feedback) tasks for math reasoning, complete prompt evaluation, mark chain-of-thought correctness, and ensure annotation guidelines compliance. In content creation, you’ll write problem sets, author explanations in LaTeX, and generate synthetic but realistic datasets that align with curriculum standards and AI training objectives across algebra, calculus, discrete math, probability, statistics, linear algebra, optimization, and numerical methods.
