Job description

• We are looking for exceptional analytical minds to join our verification team. Our work centers on a hard and rewarding problem: mathematically proving that complex systems behave exactly as specified — no edge cases, no exceptions.
• You might be an experienced formal methods practitioner, or you might come from pure mathematics, physics, or another rigorous quantitative discipline and be looking to apply your skills to concrete, high-impact engineering problems.
• If you have a talent for precise reasoning, constructing airtight arguments, and learning new technical domains quickly, we will teach you the rest.

Preferred Qualifications

• Hands-on experience with formal verification: model checking, property specification, or automated theorem proving.
• Experience with interactive theorem provers (e.g., Coq, Lean, Isabelle, ACL2) or SMT solvers (e.g., Z3, CVC5).
• Experience building verification tooling or contributing to open-source formal methods projects.
• Background in logic, type theory, discrete mathematics, or mathematical physics.

What We Offer

• The chance to work on genuinely hard correctness problems where rigor matters.
• Mentorship from experienced formal methods engineers and a structured ramp-up into the field.
• A culture that values depth, precision, and first-principles thinking.
