Formal Verification Scientist

Toronto, Canada Alignerr Full time

Overview Location: Remote. Alignerr partners with the world’s leading AI research teams and labs to build and train cutting-edge AI models. Write and formalize advanced mathematical proofs in Lean for cutting-edge AI research. Ideal for mathematicians passionate about formal verification and pushing the limits of modern proof assistants. Responsibilities Translate informal mathematical proofs into Lean (and related proof systems) 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. Sample Work You Might Do: Formalize classical proofs and compare machine-verifiable structures against textbook arguments. 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. Qualifications 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 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. Ideal Candidate — a mathematically mature problem-solver who enjoys working at the frontier of formal verification and values precision and structure. Why Join Us Competitive pay and flexible remote work. Collaborate with a team working on cutting-edge AI projects. Exposure to advanced LLMs and how they’re trained. Freelance perks: autonomy, flexibility, and global collaboration. Potential for contract extension. Application Process Submit your resume. Complete a short screening. Project matching and onboarding. PS: Our team reviews applications daily. Please complete your AI interview and application steps to be considered for this opportunity. #J-18808-Ljbffr
