Mathematical Formalization Specialist (Lean / Formal Proof Systems)

About The Role

What if your deep mathematical training could directly shape the future of AI reasoning? We're looking for mathematicians with hands-on experience in formal proof systems — especially Lean — to help push the boundaries of what machine-verifiable mathematics can express.

This is a fully remote, flexible contract role working alongside leading AI research labs. You'll tackle proofs that automated tools can't yet handle, helping map the true frontier of formal verification.

Organization: Alignerr
Type: Hourly Contract
Location: Remote
Commitment: Adaptable

What You'll Do

Translate informal mathematical proofs into Lean (and related proof systems) with a focus on clarity, structure, and machine-verifiable correctness
Analyze proofs across domains — identifying hidden assumptions, gaps, and formalizable sub-structures
Build formalizations that probe the limits of current proof assistants, especially where automation breaks down




Collaborate with AI researchers to design and refine formal verification strategies
Develop clean, reproducible proof scripts aligned with mathematical best practices and proof assistant idioms
Advise on proof decomposition, lemma selection, and structuring techniques for formal models

Who You Are

Master's degree or higher in Mathematics, Logic, Theoretical Computer Science, or a closely related field
Strong foundation in rigorous proof writing across areas such as algebra, analysis, topology, logic, or discrete mathematics
Hands-on experience with Lean (Lean 3 or Lean 4), Coq, Isabelle/HOL, Agda, or a comparable system — Lean strongly preferred
Deep enthusiasm for formal verification, proof assistants, and the future of mechanized mathematics
Ability to translate dense, informal arguments into clean, structured formal proofs
Comfortable working independently on technically demanding, open-ended problems

Nice to Have

Familiarity with type theory, the Curry–
