Alignerr Corp.; Nashville (TN); Remote; USD 110,000 - 207,000; Part time

Job summary

Alignerr is seeking a Mathematical Formalization Specialist to translate informal proofs into Lean and related proof systems. You will analyze and formalize across domains, test proof assistants, and collaborate on verification pipelines. Remote, hourly contract with flexible, task-based commitment.

Requirements include a Master's or higher in mathematics or related field, and hands-on Lean experience (Lean 3/4). Coq/Isabelle/HOL/Agda experience is valued. Join a frontier AI research effort.

Qualifications

• Master's degree or higher in Mathematics, Logic, Theoretical Computer Science, 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); experience with Coq, Isabelle/HOL, or Agda is valued

Responsibilities

• Translate informal mathematical proofs into Lean and related proof assistants with clarity and correctness
• Analyze proofs across domains to identify gaps, assumptions, and formalizable sub-structures
• Construct formalizations that test and extend proof assistants where automated tools struggle
• Collaborate with researchers to design strategies for improving formal verification pipelines
• Develop readable, reproducible proof scripts aligned with best practices and idioms
• Provide guidance on proof decomposition, lemma selection, and formal model structuring
• Investigate where automated provers break down and articulate why—complexity, missing lemmas, and libraries
