Formal Verification Scientist (Lean 4 & Mathlib) – Alignerr, Remote, Hourly Contract.
Role Overview: We are seeking mathematicians with deep training in rigorous proof construction and hands‑on experience with formal proof languages, especially Lean. This role sits at the intersection of mathematics and computer science, focusing on translating human‑written mathematical arguments into precise, machine‑verifiable formalizations.
What You’ll Do:
* Translate informal mathematical proofs into Lean with an emphasis on clarity, structure, and correctness.
* Analyze generic and domain‑specific proofs, identifying gaps, hidden assumptions, and formalizable sub‑structures.
* Construct formalizations that test the limits of existing proof assistants, especially where tools struggle or fail.
* Collaborate with researchers to design, refine, and evaluate strategies for improving formal verification pipelines.
* Develop highly readable, reproducible proof scripts aligned with mathematical best practices and proof assistant idioms.
* Provide guidance on proof decomposition, lemma selection, and structuring techniques for formal models.
* Investigate where automated provers break down and articulate why (complexity, missing lemmas, insufficient libraries, etc.).
* Create Lean proofs that reveal deeper patterns or generalizations implicit in the original mathematics.
Requirements:
* Master’s degree (or higher) in Mathematics, Logic, Theoretical Computer Science, or a closely related field.
* Strong foundation in rigorous proof writing and mathematical reasoning across areas such as algebra, analysis, topology, logic, or discrete math.
* Hands‑on experience with Lean (Lean 3 or Lean 4), Coq, Isabelle/HOL, Agda, or comparable systems, with Lean strongly preferred.
* Deep enthusiasm for formal verification, proof assistants, and the future of mechanized mathematics.
* Ability to translate informal arguments into clean, structured formal proofs.
Preferred Qualifications:
* Prior experience with data annotation, data quality, or evaluation systems.
* Familiarity with type theory, Curry‑Howard correspondence, and proof automation tools.
* Experience with large‑scale formalization projects (e.g., mathlib).
* Exposure to theorem provers where automated reasoning frequently fails or requires manual scaffolding.
* Strong communication skills for explaining formalization decisions, edge cases, and reasoning strategies.
Benefits:
* Competitive pay: $70–$150 per hour.
* Flexible remote work.
* Collaborate with a team on cutting‑edge AI research.
* Exposure to advanced large language models and their training processes.
* Freelance perks: autonomy, flexibility, global collaboration, potential for contract extension.
