About the role
Join a leading AI lab's cutting-edge GenAI team to be at the core of the AI revolution, where your expertise fuels the development of the most advanced Large Language Models.
1\. Overview
Join a leading AI lab's cutting-edge GenAI team and help build foundational AI models from the ground up. We're seeking talented Formal Mathematics specialists and mathematicians with hands-on experience with interactive theorem provers such as Lean, Coq (Rocq) or Isabelle to bring rigorous mathematical and formal verification expertise and elevate the quality of our AI training data.
This is a W-2 employment position with Cincinnatus LLC, with the opportunity to be placed at a leading AI Lab as part of their extended workforce.
2\. Key Responsibilities
- Guide research and engineering teams to close knowledge gaps and improve AI model performance in formal mathematics and theorem proving, formalized proofs, and graduate-level mathematics topics.
- Design challenging, domain-relevant tasks, and write accurate and well-structured solutions to formal mathematics and theorem proving problems.
- Evaluate formal mathematics and theorem proving tasks and solutions and provide clear, written technical feedback.
- Write, check and repair formal proofs and statements in Lean, Coq or Isabelle, and translate informal mathematics into formal statements.
- Develop rubrics to assess the correctness, faithfulness and elegance of formalized statements and proofs.
- Collaborate with other subject matter experts to ensure consistency and accuracy in training data.
3\. Core Qualifications
- Graduate-level training in mathematics, computer science or logic (MS, PhD or PhD candidate), or equivalent professional experience in formal verification.
- Hands-on experience writing proofs in Lean 4 (Mathlib), Coq (Rocq), Isabelle/HOL or a comparable proof assistant, evidenced by contributions, projects or publications.
- Strong background in proof-based mathematics (algebra, analysis, number theory, combinatorics or logic).
- Demonstrable track record of mathematical or formal verification work.
- Ability to engage reliably for at least 20 hours/week during weekdays.
- Strong written communication skills and the ability to explain complex technical decisions clearly.
