Overview A leading AI lab is looking for Lean engineers, formal mathematicians and proof engineers to help its AI models state and prove mathematics correctly. You'll write and review Lean 4 proofs, turn informal math into precise formal statements, and help the lab's researchers judge whether a model's proof is not just accepted by the checker but actually proves the right thing. If you enjoy writing Lean, know your way around mathlib, and can explain why a formalization is faithful or subtly wrong, this role is for you. This is a part-time commitment of at least 20 hours per week, with the option to increase to up to 40 hours per week. This is a W-2 employment position with Cincinnatus LLC (or appropriate international entity), with the opportunity to be placed at a leading AI lab as part of their extended workforce. 2. Key Responsibilities Write correct, idiomatic Lean 4 statements and proofs that compile against current mathlib, across areas such as algebra, analysis, number theory, combinatorics and logic. Formalize natural-language mathematics, from competition problems and textbook results to research-level lemmas, paying close attention to whether the formal statement matches the original. Review AI-generated Lean statements and proofs, find where they fail or prove the wrong thing, and give clear, specific written feedback. Help define guidelines and rubrics for proof quality, statement fidelity and mathlib conventions. Collaborate with other Lean engineers and the lab's researchers to keep standards consistent and keep raising the quality bar. 3. Core Qualifications Hands-on experience writing formal proofs in Lean 4, for example mathlib contributions, a formalization project, a Lean library or tool, or autoformalization work. Comfort with mathlib and Lean 4 tactics, and with finding and using the right lemmas. A strong background in proof-based mathematics, theoretical computer science or logic, through a degree or a research record. The ability to turn a written statement and proof into a correct formal statement and a proof that checks. Ability to engage reliably for at least 20 hours/week during weekdays. Clear written communication and the ability to explain proof strategy and formalization choices precisely. Nice to have: experience with other proof assistants or dependently typed languages (Coq/Rocq, Isabelle, Agda, Haskell), Lean metaprogramming, or AI-for-math work such as LLM provers, Lean agent environments, or benchmarks like miniF2F, ProofNet or PutnamBench.
