Lean 4 Mathematical Formalization Expert

Lean 4 Mathematical Formalization Expert$170-200/hr Remote Freelance STEMAbout the RoleWhat if your deep expertise in formal mathematics could directly shape how AI reasons, proves, and verifies mathematical truths? We're looking for Lean 4 specialists to translate complex mathematical arguments into precise, machine-checked formalizations — working at the frontier where mathematics meets artificial intelligence.This is a fully remote, flexible contract role built for mathematicians and formal verification experts who want to do genuinely challenging, high-impact work on their own schedule.What You'll DoFormalize mathematical content from natural language sources — textbooks, articles, and exercises — into valid, compilable Lean 4 codeTranslate theorems, lemmas, propositions, and proofs into precise formal representations using Lean 4Ensure formal code accurately captures the mathematical meaning and logical structure of the original statementsReview and validate Lean 4 formalizations for correctness, consistency, and logical soundnessIdentify ambiguities, missing assumptions, or logical gaps in informal mathematical descriptionsContribute to high-quality datasets pairing human-written mathematics with formal Lean 4 equivalents for AI trainingWho You AreStrong hands-on experience with Lean 4 — you write precise, correct, and maintainable codeSolid background in mathematics, formal logic, or formal verificationComfortable reading advanced mathematical texts and translating them into formal systemsExceptional attention to detail and a rigorous logical mindsetInterested in AI, automated reasoning, and the future of mathematical verificationSelf-directed and reliable when working independently on complex, open-ended problemsNice to HaveExperience with other theorem provers or formal systems (Coq, Isabelle, Agda, Metamath, etc.)Prior involvement in AI training, expert annotation, or reasoning-focused datasetsBackground in formal methods research or proof assistant developmentAcademic or professional experience in pure or applied mathematicsWhy Join UsWork on cutting-edge AI projects alongside leading research labsFully remote and flexible — work when and where it suits youFreelance autonomy with the structure of clearly defined, meaningful tasksHigh-impact work — your formalizations directly improve how AI models reason about mathematicsTop performers are invited to advanced tracks and extended contracts with greater scope and responsibility
