Formal Mathematics Specialist (Lean / Coq / Isabelle)

• 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.

• 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.
