Senior/Staff Software Engineer

Who we are

At Logical Intelligence, we're revolutionizing software development with AI-powered formal verification. We've developed groundbreaking agents that provide mathematical guarantees of code correctness, ensuring that software behaves exactly as intended while proactively identifying bugs and security vulnerabilities. We’ve won ​​a well-known formal verification benchmark called PutnamBench, which consists of 672 hard math problems from the William Lowell Putnam Exam, the oldest collegiate mathematics competition in North America. Backed by a world-class team – including 6 ICPC medalists, 10 PhDs, a Fields Medalist and an ACM Turing Award winner – we're building the future where all code is provably correct.

About the role

Join our team as an SWEngineer and help us push the boundaries of what's possible in logical reasoning!  We’re looking for a motivated software engineer to build and refine the systems, tooling, and infrastructure that power AI-driven formal verification at scale. You’ll work closely with a world-class team of formal verification researchers and ICPC winners to create groundbreaking technology that makes mathematically proven software correctness practical for real-world codebases.
