Applied Formal Methods Researcher (Lean 4)
About The Role
What if your deep mathematical training could directly shape how AI understands and reasons about formal proof? We're looking for Applied Formal Methods Researchers to translate rigorous human mathematical arguments into machine-verifiable Lean 4 formalizations — working at the very frontier of what automated reasoning can express and achieve.
This is a fully remote, flexible contract role designed for mathematicians who love precision, structural elegance, and the intellectual challenge of bridging human intuition with machine-verifiable logic.
Organization: [Alignerr] Type: Hourly Contract Location: Remote Commitment: 10–40 hours/week
What You'll Do
- Translate informal mathematical proofs into Lean 4 (and related proof systems) with an emphasis on clarity, structure, and correctness
- Analyze proofs across domains to identify gaps, hidden assumptions, and formalizable sub-structures
- Construct formalizations that test and expose the limits of existing proof assistants, particularly where automated tools struggle or fail
- Collaborate with researchers to design, refine, and evaluate strategies for improving formal verification pipelines
- Develop readable, reproducible proof scripts aligned with mathematical best practices and proof assistant idioms
- Provide guidance on proof decomposition, lemma selection, and formal model structuring strategies
- Investigate breakdowns in automated provers, articulating root causes like complexity, missing lemmas, or insufficient libraries
- Formalize classical proofs and compare machine-verifiable structures against textbook arguments
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
