How to Apply for Metaprogrammer, Mathlib Initiative
at Renaissance Philanthropy
🏢 About Renaissance Philanthropy
Renaissance Philanthropy is a nonprofit that aims to increase the ambition of philanthropists, scientists, and innovators by advising philanthropists, surfacing breakthrough ideas, and incubating ambitious initiatives. Working here means contributing to high-impact projects that push the boundaries of science and technology, with a focus on long-term, transformative change.
About This Role
As a Metaprogrammer on the Mathlib Initiative, you will design and implement Lean metaprograms—tactics, linters, and code actions—to accelerate mathematical formalization in Mathlib. Your work will directly enable mathematicians and computer scientists to formalize mathematics more efficiently, making a significant impact on the future of mathematical knowledge and automated reasoning.
💡 A Day in the Life
A typical day might involve writing or refining a tactic in Lean to automate a common proof pattern, then testing it on a variety of Mathlib examples. You'd also review pull requests from community contributors, providing constructive feedback, and participate in discussions on the Mathlib Zulip chat to coordinate with other maintainers and users.

📝 Tips for Applying to Renaissance Philanthropy
Highlight specific examples of Lean metaprograms you have designed or contributed to, ideally with links to PRs or code in Mathlib.
Demonstrate your experience with the computational methods mentioned (linear algebra, polynomials, interval arithmetic) by describing relevant projects or formalizations.
Show your engagement with the Mathlib community: mention any discussions, issue reports, or contributions you've made.
Tailor your cover letter to explain why you're excited about accelerating mathematical formalization and how your skills align with the initiative's goals.
Since it's a remote, fixed-term role, emphasize your ability to work independently and manage your time effectively, with a clear track record of remote collaboration.
✉️ What to Emphasize in Your Cover Letter
- Emphasize your proven ability to write Lean tactics and linters, with concrete examples of how they improved proof development. - Highlight your experience with Mathlib or similar open-source formalization projects, showing you understand the codebase and community norms. - Connect your computational methods expertise (linear algebra, polynomials, interval arithmetic) to the specific challenges in Mathlib. - Express enthusiasm for the mission of Renaissance Philanthropy and how this role contributes to broader scientific and philanthropic goals.
Generate Cover Letter →🔍 Research Before Applying
To stand out, make sure you've researched:
- → Explore Renaissance Philanthropy's website to understand their mission, current initiatives, and impact.
