Job summary

DataAnnotation is seeking a Mathematician to evaluate and correct mathematical reasoning across everything from competition problems to graduate-level material. Your judgment becomes the standard the models learn from.

You will craft problems, review AI solutions step by step, and write the gold-standard solution with the rigor of a referee report. This role emphasizes precise proofs and clear English for training signals.

Qualifications

• Strong background in pure or applied mathematics through graduate study, competition math, or equivalent experience.
• Fluency writing precise, well-structured proofs (LaTeX comfort helps).
• Clear written English: your explanations are the training signal.
• No degree required. We care about what you can do, not where you learned it.

Responsibilities

• Craft problems that expose weak mathematical reasoning, from olympiad-style puzzles to graduate-level proofs.
• Review AI solutions step by step: catch invalid derivations, flag unjustified leaps, and rate the quality of the reasoning.
• Write the gold-standard solution when the model falls short, with the rigor of a referee report.

Job description

Frontier models still fail at rigorous multi-step mathematics: invalid derivations, unjustified leaps, and confidently wrong final answers. Automated checks can't grade a proof. You can.

As a Mathematician you'll evaluate and correct mathematical reasoning across everything from competition problems to graduate-level material, and your judgment becomes the standard the models learn from.

What you'll actually do

• Craft problems that expose weak mathematical reasoning, from olympiad-style puzzles to graduate-level proofs.
• Review AI solutions step by step: catch invalid derivations, flag unjustified leaps, and rate the quality of the reasoning.
• Write the gold-standard solution when the model falls short, with the rigor of a referee report.

What we look for

• Strong background in pure or applied mathematics through graduate study, competition math, or equivalent experience.
• Fluency writing precise, well-structured proofs (LaTeX comfort helps).
• Clear written English: your explanations are the training signal.
• No degree required. We care about what you can do, not where you learned it.
