Pure Mathematics and Lean 4 Specialist – Freelance AI Trainer Project
Job Description, Responsibilities & Requirements
About the Position
Are you a theoretical mathematics expert eager to shape the future of AI? Large-scale language models are rapidly advancing, and their ability to handle rigorous proof-based reasoning depends on high-quality mathematical training data. With your advanced expertise, tomorrow’s AI can better understand abstraction, logic, measure theory, homotopy, and the deep structures of modern mathematics. That training data begins with you - your insight will help power the next generation of AI.
Responsibilities
- Construct and evaluate complex proofs
- Substantiate the mathematical reasoning for correctness and rigor
- Identify subtle conceptual or logical failures
- Translate material to successfully build in.lean syntax
- Collaborate with the team to refine prompts, evaluation frameworks, and mathematical reasoning benchmarks
Requirements
- Fluency in Lean 4, the proof assistant and programming language
- In-progress or freshly earned PhD or current PostDoc experience in pure mathematics
- Strong command of core areas such as Markov’s and Chebyshev’s inequalities, Hoeffding bounds, convergence theorems, the Carathéodory extension theorem, the Riesz representation theorem, Banach–Alaoglu, Lax–Milgram, stochastic approximation, Van Kampen’s theorem, the Yoneda embedding, and representability in cohomology
- Clear, metacognitive communication skills
We Offer
- Pay range of $35 to $65 per hour, with the exact rate determined after evaluating your experience, expertise, and geographic location
- Opportunity to supply a secure computer and high-speed internet
