Lean Engineer
About The Position
Resolution is seeking a Lean Engineer to establish and scale the organization's proficiency in Lean and autoformalization. This role involves providing expertise and strategic guidance on Lean usage, developing structures to support autoformalization efforts, and improving the reliability and maintainability of shared Lean projects. The primary focus is on enabling researchers and AI agents to effectively utilize Lean for theoretical research, rather than on writing Lean code directly. The engineer will work closely with researchers, central engineering, and automation teams to foster Lean wisdom across the organization and build robust infrastructure for automated formalization.
Requirements
- Several years of experience writing Lean and mathlib.
- Expertise in Lean community practices.
- AI power user with experience in autoformalization.
- Clear communication skills and enjoyment of working closely with researchers and engineers.
- Strong mathematics or theoretical computer science background (Bachelor’s at minimum).
- Desire to contribute to the alignment of artificial superintelligence.
Nice To Haves
- Contributions to mathlib or other substantial Lean libraries.
- Experience designing or maintaining large formalization projects.
- Experience with Lean tooling, tactic development, metaprogramming, or proof automation.
- Experience with AI-assisted mathematical research or automated evaluation.
Responsibilities
- Nurture Lean wisdom throughout the organization and be a champion of Lean and autoformalization.
- Build and maintain the structures so we can trust agent autoformalization outputs: proof harnesses, code review workflows, etc.
- Build and maintain shared Lean libraries with clear definitions, useful abstractions, and a structure that supports review and further (automated) research.
- Consolidate overlapping formalizations, resolve inconsistent definitions, and build shared foundations for researchers and agents to reuse.
- Improve the reliability, maintainability, and performance of shared Lean projects.
- Support researchers in developing custom tools, tactics, and workflows to help them make progress.
- Ensure that all responsibilities are understood to be heavily AI-assisted.
Benefits
- Five weeks of paid vacation plus public holidays
- Comprehensive medical, dental, and vision insurance
- Unlimited sick leave
- Unconditional 401(k) contribution equal to 4% of salary
