Job Purpose
Job Purpose
We are seeking highly skilled External Research Collaborator to contribute to the development, scaling, and maintenance of one of our client´s open-source autoformalization ecosystem.
This interdisciplinary role sits at the intersection of formal mathematics, interactive theorem proving (specifically Lean 4 and Mathlib), and generative AI engineering. Collaborators will focus on building, evaluating, and refining multi-agent pipelines that translate informal mathematical natural language into verified, compilable Lean code. Additionally, collaborators will play a critical role in expanding the mathematical coverage of our client´s dataset, ensuring mathematical faithfulness, proof integrity, and robust integration with various systems.
Job Overview
Key Responsibilities
Autoformalization Pipeline & AI Tooling Engineering

• Develop, scale, and maintain multi-agent AI pipelines designed to translate complex mathematical texts into verified Lean 4 code.

• Evaluate pipeline performance, diagnose verification and compilation failures, and implement systematic engineering solutions to improve autoformalization reliability.

• Research and implement automatic tactic generation and domain-specific proof search strategies to assist LLMs in formal verification.

Dataset Curation & Verification

• Expand and curate our client´s dataset by formalizing missing mathematical results, theorems, and proofs.

• Conduct rigorous peer-reviews of AI-generated Lean statements and proofs to guarantee mathematical faithfulness, proof integrity, and logical validity.

• Ensure optimal code quality and promote the idiomatic, modular reuse of the existing Mathlib library.

3. Community Engagement & Research Collaboration

• Actively collaborate with the global mathematics, Lean, and Mathlib open-source communities to align formalization efforts and upstream reusable code.

• Support domain-specific formalization projects (e.g., algebra, analysis, topology) depending on specialized mathematical background.

• Develop robust evaluation methodologies to benchmark machine-learning-driven formal reasoning tools.

Skills & Experience
Minimum Qualifications:

• Educational Background: Ph.D. or Master’s degree in Mathematics, Computer Science, or a closely related quantitative field with a strong focus on formal methods, mathematical logic, or theoretical computer science.

• Mathematical Maturity: Exceptional mathematical foundation, with a proven ability to understand, translate, and verify graduate-level mathematical proofs.

• Lean 4 Experience: Hands-on, practical experience writing formal proofs in Lean 4 and familiarity with the design and structure of Mathlib.

• AI Tooling & Programming: Strong software engineering fundamentals in Python and experience working with LLMs, prompt engineering, and multi-agent developer tools.

• Autonomy: Demonstrated ability to manage open-ended research and engineering projects independently in a remote or collaborative setting.

Preferred Qualifications:

• Active contributor to Mathlib or other formal proof repositories (e.g., Coq, Isabelle/HOL).

• Background in Machine Learning for Code, Automatic Theorem Proving (ATP), or reinforcement learning for symbolic reasoning.

• Familiarity with compiler design, AST manipulation, or parser development in the context of Lean.

• A strong track record of open-source software contributions or research publications in formal methods, AI, or mathematics.
