About The Role What if your deep knowledge of formal mathematics could directly shape how the most advanced AI systems in the world reason, prove, and think? We're looking for mathematicians with a passion for rigorous proof and formal systems to help build the mathematical foundations that frontier AI depends on. This is a fully remote, adaptable contract role working at the intersection of pure mathematics, logic, and cutting-edge AI research.

If you live and breathe formal proof — and especially if you know your way around Lean 4 — this is a rare opportunity to do deeply meaningful technical work on your own schedule.

Organization: Alignerr

Type: Hourly Contract

Location: Remote

Commitment: 10–40 hours/week What You'll Do Formalize advanced mathematical arguments and theorems in Lean 4, spanning a wide range of mathematical disciplines

Contribute to the growth and quality of large-scale formal mathematical libraries, including mathlib

Construct clean, readable, and well-structured formal proofs that translate informal mathematical reasoning into rigorous machine-checkable form

Audit and verify existing formal proofs for correctness, completeness, and logical integrity

Work at the frontier of AI research,



helping train the next generation of mathematically capable language models Who You Are Hold a Master's degree or PhD in Mathematics or a closely related field

Possess a strong background in rigorous mathematical proof writing and logical reasoning

Have hands-on experience with formal proof assistants — Lean 4 strongly preferred

Can fluently translate informal mathematical ideas into structured, machine-verifiable formal proofs

Self-motivated and comfortable working independently in a remote, asynchronous setting Nice to Have Prior experience with proof verification, theorem proving, or mathematical formalization projects

Familiarity with mathlib or other large-scale formal mathematical libraries

Background in data annotation, data quality evaluation, or AI training workflows

Experience across multiple mathematical domains — topology, algebra, analysis, logic, and beyond Why Join Us Work on frontier AI research alongside the world's leading AI labs and research teams

Fully remote and flexible — structure your work around your life, not the other way around

Freelance autonomy with the intellectual depth of meaningful, high-stakes technical work

Contribute directly to formal mathematical libraries that will outlast any single project

Gain rare exposure to how cutting-edge large language models are built and trained

Potential for ongoing work and contract extension as new projects launch
