How to Apply for Lean Proof Contractor

at Dovetail

🏢 About Dovetail

Dovetail is a unique research group focused on foundational mathematics to understand AI agents, specifically aiming to help humanity safely navigate powerful AI systems. Unlike typical tech companies, they combine mathematical rigor with AI safety research, offering a chance to contribute directly to preventing existential risks from advanced AI.

About This Role

As a Lean Proof Contractor, you'll formalize mathematical AI safety research in Lean, converting published papers and team conjectures into verified proofs while teaching team members to use Lean effectively. This role directly impacts Dovetail's core mission by creating rigorous mathematical foundations for AI safety research and improving the team's mathematical feedback loops.

💡 A Day in the Life

A typical day involves writing Lean proofs for mathematical AI safety conjectures, reviewing and converting published papers into formalized theorems, and conducting teaching sessions with team members on Lean usage. You'll also maintain Mathlib extensions while collaborating remotely with researchers to improve mathematical feedback loops.

🎯 Who Dovetail Is Looking For

  • Has substantial experience writing proofs in Lean, particularly with Mathlib extensions and best practices
  • Possesses a strong mathematical background enabling conversion of complex AI safety papers into formal proofs
  • Demonstrates teaching ability to transfer Lean skills to team members with varying mathematical backgrounds
  • Can balance independent proof work with collaborative teaching and Mathlib maintenance responsibilities

📝 Tips for Applying to Dovetail

1

Showcase specific Lean projects in your portfolio, especially those involving Mathlib extensions or formalizing published mathematics

2

Highlight any experience with AI safety or agent foundations mathematics, even if tangential

3

Demonstrate teaching experience through examples of knowledge transfer in technical settings

4

Reference Dovetail's published research or blog posts to show genuine interest in their specific approach to AI safety

5

Prepare to discuss how you'd approach converting a complex mathematical paper into Lean, with specific examples from your experience
