Mathematics QA

Job Description

OpenTrain partners with leading AI companies to build safer, smarter systems. We hire subject-matter experts to audit and improve model reasoning. We’re seeking Mathematics QA / AI Trainers to review math prompts and model responses, verify step-by-step reasoning, and author improved solutions and prompts that raise quality and rigor.

What you’ll do

• Audit math Q&A items and model outputs for correctness, completeness, notation, and structure.
• Evaluate responses against detailed QA rubrics; assign ratings and write concise rationales.
• Draft improved prompts, reference solutions, and error-aware feedback (SFT/RLHF/evaluation).
• Run quick validations in Python (functions/sanity checks; NumPy/SymPy/Pandas helpful).
• Flag edge cases, propose rubric refinements, and help maintain dataset consistency across topics.

Minimum Qualifications

• Bachelor’s in Math or related field (Master’s/PhD preferred).
• Hands-on Python for quick checks/validation.
• Able to evaluate algebra, calculus, linear algebra, probability, and statistics reasoning.
• Meticulous with mathematical notation, proofs, and solution structure.
• Clear written English; comfortable following strict QA rubrics and writing constructive feedback.
• Reliable computer/internet; able to pass an AI interview and QA calibration.

Contract & Schedule

• Type: Contract (remote).
• Hours: Less than 20 hours/week; minimum 15 hours/week (flexible).
