About the role

Mathematics & STEM Textbook QA Specialist (OCR + LaTeX) Mercor is partnering with a leading frontier AI research lab on an initiative to improve math and STEM reasoning. We’re building high-quality training and evaluation data from public-domain textbooks, and we’re looking for detail-oriented STEM experts to validate and repair extracted problem–solution content.

This role is ideal for people who are strong at proof-based math reading , precise transcription , and LaTeX formatting , and who enjoy meticulous quality work.

Key Responsibilities

  • Validate math/STEM question–answer pairs extracted from textbook PDFs, identifying errors introduced by OCR or extraction.
  • Compare extracted text to the source PDF and correct transcription issues (symbols, subscripts/superscripts, missing terms, etc.).
  • Fix and standardize LaTeX formatting so all expressions render correctly and match the source.
  • Extract and label relevant context (problem statements, surrounding definitions, hints, solution steps, short answers) and record correct PDF viewer page numbers.
  • Revise raw textbook content into clean QA format when the original is demonstrative (e.g., “Show that…”) or references missing equations/figures.
  • Assess solution quality (correctness, completeness, logical consistency) and flag gaps, incorrect steps, or mismatches with the stated answer.
  • Maintain consistently high standards for precision, structure, and correctness.

Required Qualifications

  • Strong proficiency with LaTeX math formatting (required).
  • Background in Mathematics, Physics, Engineering, or related STEM (BA/BS/Masters/PhD or equivalent rigor).
  • Comfort reading and verifying multi-step mathematical reasoning (including proofs and textbook solutions).
  • Excellent attention to detail and ability to follow a structured workflow exactly.
  • Strong written communication for clear, concise technical notes.

Preferred Qualifications

  • Proof-based coursework (e.g., real analysis, abstract algebra, proof-based linear algebra).
  • Experience as a TA/grader, tutor, contest solution writer, or math editor.
  • Familiarity with common OCR failure modes in STEM text (misread symbols, broken equations, malformed fractions, etc.).
  • Ability to handle advanced undergraduate / occasional graduate-level material.

What You’ll Be Evaluating You’ll work on a range of textbook-style content, including:

  • Exercises and examples across math and STEM
  • Proof-oriented problems
  • Occasionally multi-part questions, with dependencies across subparts
  • Problems that require careful handling of figures/diagrams and referenced equations

More About The Opportunity

  • Potential commitment: 15 hours/week minimum, up to 40 hours/week
  • Approximate project length: 2-3 weeks
  • Work is structured and quality-focused; speed matters less than correctness
