You will collaborate with researchers to refine verification pipelines, ensure readability, and apply Lean idioms to complex mathematical problems.

Qualifications

• Master's degree or higher in Mathematics, Logic, or a closely related field.
• Strong foundation in rigorous proof writing across algebra, analysis, topology, logic, or discrete math.
• Hands-on experience with Lean (Lean 3 or Lean 4) and other proof assistants such as Coq, Isabelle/HOL, or Agda.

Responsibilities

• Translate informal mathematical proofs into Lean 4 formalizations.
• Analyze proofs across domains and identify gaps, assumptions, and formalizable sub-structures.
• Develop readable, reproducible Lean proofs aligned with best practices and Lean idioms.
• Collaborate with researchers to improve formal verification pipelines.
