About AI Training and Mathematics Quality Work

AI training is the human side of building artificial intelligence. People review examples, evaluate model responses, and provide structured feedback so AI systems can produce more accurate, useful, and reliable results.

In this role, your mathematics expertise will help evaluate whether AI-generated content is logically sound, mathematically correct, clearly explained, and compliant with project standards.

• Contribute to cutting-edge mathematics AI training projects
• Work remotely with flexible part-time contractor scheduling
• Use specialist mathematics knowledge to improve model quality

The Role

OpenTrain is hiring a Mathematics Quality Assurance Lead to oversee quality and consistency across mathematics AI training projects. You will review AI-generated mathematics content and trainer QA work, assess outputs against project guidelines, provide precise written feedback, and help maintain a consistently high standard across remote teams.

The role also includes identifying recurring quality issues, communicating updates to trainers and QAs, supporting onboarding, maintaining documentation, and helping activate contributors who are not working consistently. This is an hourly, remote contractor role focused on mathematics AI training and quality leadership.

• Employment type: Contractor and part-time
• Location: United States only
• Time commitment: 20+ hours per week
• Compensation: $25 to $75 per hour
• Experience level: Intermediate

What You'll Do

• Review AI-generated math explanations, proofs, derivations, calculations, word-problem solutions, diagrams, and step-by-step reasoning.
• Check work for mathematical correctness, clarity, notation quality, formatting, and adherence to project-specific rubrics.
• Evaluate mathematical reasoning, identify flawed assumptions, and catch calculation or proof errors.
• Provide ongoing written feedback to trainers and QAs, escalating recurring or critical issues when needed.
• Communicate project updates, quality expectations, and mathematics-specific standards across remote teams.
• Create and maintain style guides, trackers, FAQs, honeypots, calibration tasks, examples, and onboarding materials.
• Run onboarding and training calls for contributors.
• Help improve scalable QA workflows for mathematics projects.
• Help activate contributors who are not working consistently.

Required Qualifications

You should have strong mathematics reasoning skills, clear written English communication, and experience evaluating math solutions, proofs, or explanations. The role requires comfort collaborating in remote technical environments and applying detailed project rubrics consistently.

• Broad familiarity with algebra, geometry, trigonometry, calculus, linear algebra, discrete mathematics, probability, statistics, number theory, combinatorics, differential equations, and proofs.
• Experience in mathematics, teaching, tutoring, research, quantitative analysis, technical writing, problem creation, assessment design, or math-content review.
• Ability to assess logical reasoning and explain quality issues precisely in writing.
• Clear written English communication.
• Experience with AI training, data annotation, LLM evaluation, or rubric-based quality review is a strong plus.

Who Should Apply

This opportunity is suited to mathematics professionals, educators, tutors, researchers, quantitative analysts, technical writers, and experienced reviewers who want to contribute directly to the development of AI systems. It is especially relevant if you enjoy finding subtle errors, improving explanations, and creating standards that help distributed teams produce dependable work.

• Mathematics specialists with broad subject coverage
• Teachers, tutors, researchers, and assessment designers
• Professionals experienced in reviewing proofs, calculations, or explanations
• Candidates interested in flexible, remote AI training work
• Applicants able to commit to 20 or more hours per week
