Harmonic is building a mathematical reasoning engine that combines Lean 4 and reinforcement learning to verify AI reasoning with absolute precision. Unlike traditional AI systems that make probabilistic guesses, Harmonic's Aristotle platform has demonstrated gold-medal-level performance on the 2025 International Math Olympiad and resolved long-standing open mathematical problems.
As a Formal Verification Engineer, you will be at the forefront of applying this breakthrough technology to real-world production systems. Your primary responsibilities include translating customer design intent into precise formal properties, leveraging Aristotle to execute formal proofs, and diagnosing verification failures with rigor. You will manage project scope and technical risk while maintaining clear communication with customers, often traveling to their sites to understand their most critical verification challenges.
The role requires you to rapidly develop deep technical understanding of complex, production-ready code across diverse domains—from hardware to software systems. You will identify which properties are business-critical and translate those requirements into targeted formal specifications that Aristotle can prove. Your field insights will directly inform product improvements, creating a feedback loop between customer needs and platform capabilities.
You must hold a BS in Computer Science, Mathematics, or equivalent industry experience, with direct hands-on expertise in hardware verification, software verification, or interactive theorem proving. Proficiency in at least one proof assistant (Lean, Coq, Isabelle, or Agda) and a strong foundation in formal methods and mathematical logic are essential. You should demonstrate the ability to independently navigate complex concepts, manage risks and deadlines autonomously, and calibrate your communication from deep technical discussions to high-level business justifications.
Preferred qualifications include an MS or PhD, Lean 4 expertise, experience applying formal verification to real industrial systems, and a track record of high-caliber research (publications, patents, or significant open-source contributions).
Harmonic offers unlimited PTO, 401(k) matching, 100% employer-paid health/vision/dental for employees (50% for dependents), and HSA options.
