You will bridge the gap between formal methods and production AI, building tools to verify AI-generated code at scale. Leveraging Lean 4 and the AXLE infrastructure, you’ll transform deep expertise in proof assistants into accessible, fast software. Join an elite team from Meta FAIR and the Lean ecosystem to make verification practical.
Formal Verification Expert at Axiom
Axiom is building a $1.6B foundation for verified reasoning, uniting AI and Lean 4 theorem proving to verify every line of AI-generated code. Having already solved open research conjectures with zero human guidance, they are now scaling formal verification into a practical product for the AI era.

Role overview
Axiom is a San Francisco-based AI startup valued at $1.6B that raised $250M in seed and Series A funding to build the foundation for verified reasoning.
What you will do
- Engineer product-ready software that integrates formal verification tools like Lean 4 into developer workflows and cloud infrastructure.
- Develop and scale AXLE, the cloud environment for automated theorem proving, proof verification, and automated proof repair.
- Collaborate with AI researchers and software engineers to ensure every line of AI-generated code meets the highest standards of mathematical rigor.
Who this is a fit for
- Possesses deep expertise in formal verification using proof assistants such as Lean, Coq, Isabelle/HOL, or Agda.
- Demonstrates a proven track record of building and shipping production software, developer tools, or large-scale infrastructure beyond academic research.
- Thrives in a fast-paced startup environment where the goal is to bridge the gap between complex mathematical proofs and practical AI applications.
Why this role is remarkable
- Join a $1.6B unicorn at the absolute frontier of AI and mathematics, working on an AI mathematician that has already solved open research conjectures.
- Build the infrastructure (AXLE) that makes formal verification practical for the first time, moving beyond research into production-grade tools for AI-generated code.
- Work alongside a world-class team recruited from Meta FAIR, top-tier mathematics programs, and the core Lean 4 development ecosystem.
