Experience with Lean (Lean 3/4) or other proof assistants is highly desired.
Ability to work independently on rigorous formalization tasks.

Responsibilities

Translate informal proofs into Lean 4 formalizations with clarity and correctness.
Analyze proofs to identify gaps and formalizable sub-structures.
Push the boundaries of proof assistants by constructing challenging formalizations.
Collaborate with AI researchers to improve verification pipelines.
Develop clean proof scripts in Lean idioms and maintain reproducibility.
Explain formalization decisions and edge cases clearly.
Investigate automated provers' weaknesses and document findings.
