Full-time position South Korea

We are seeking exceptionally talented Math Experts to contribute to the training of frontier AI models. This is a rare opportunity for elite mathematicians to directly shape the next generation of artificial intelligence by producing high-quality mathematical reasoning data, evaluating model outputs, and solving research-grade problems that push the boundaries of what AI can do.

The ideal candidate has competed at the highest levels of mathematical competition — including the International Mathematical Olympiad (IMO), Putnam, or equivalent national and international competitions — and brings deep quantitative expertise from academia or industry.

Responsibilities

• Solve advanced mathematical problems across competition math, proof-based mathematics, and quantitative reasoning to generate frontier AI training data
• Evaluate and provide expert feedback on AI-generated mathematical reasoning and proofs
• Develop original, research-grade problems and solutions spanning areas such as number theory, combinatorics, algebra, real analysis, and probability
• Apply quantitative and statistical methods to assess and improve model performance on mathematical benchmarks
• Collaborate with AI research teams to identify gaps in mathematical reasoning and design targeted training tasks

Qualifications

• Demonstrated participation or achievement in elite competitive mathematics (IMO, USAMO, Putnam, or equivalent national/international olympiads)
• Deep proficiency across multiple mathematical disciplines including proof-based mathematics, combinatorics, number theory, real and complex analysis, linear algebra, and probability
• Strong quantitative background with experience applying mathematical rigor to research or industry problems (e.g., quantitative finance, theoretical CS, or academic research)
• Bachelor's degree or higher in Mathematics, Applied Mathematics, Statistics, or a related field (advanced degree preferred)
• Ability to produce precise, well-structured mathematical writing
