While most AI makes maximum-likelihood guesses, Harmonic's Aristotle uses Lean 4 and reinforcement learning to verify its reasoning and results.\nFollowing our Gold Medal-level performance on the 2025 International Math Olympiad (IMO) and the successful resolution of long-standing open problems, we are proving that AI can master the most rigorous domains of human thought. Backed by some of the world’s most prominent investors, we are intentionally scaling an elite technical team.\nVisit ourcompany blogto learn more about what we are working on!\nAbout the Role\nWe are seeking a Formal Verification Engineer to verify production hardware and software with Aristotle, our formal reasoning agent. In this role, you will work with customers to scope requirements, define properties, execute formal proofs, and deliver reproducible workflows while feeding insights back to product and research. We are looking for a rigorous problem-solver with expertise in formal verification that can adapt readily based on customer requirements and expand the boundaries of Aristotle to push it further.\nKey Responsibilities\nTranslate design intent into precise properties, utilize Aristotle intensively to execute formal proofs, and accurately diagnose verification failures.\n\nManage project scope and technical risk while maintaining direct, clear communication with customers\n\nQuickly develop a comprehensive technical understanding of complex production-ready code, often across new or unfamiliar domains\n\nIdentify and analyze the critical properties customer teams need proved, translating business-critical requirements into clear, targeted formal specifications\n\nWork with the product team to improve Aristotle based on observations in the field\n\nTravel to customer sites on behalf of the company\n\nMinimum Qualifications\nBS in Computer Science, Mathematics, a related field, or equivalent industry experience\n\nDirect experience in hardware verification, software verification, or interactive theorem proving (ITP)\n\nDemonstrated ability to independently navigate complex concepts, manage risks and deadlines autonomously\n\nAbility to calibrate communication seamlessly depending on the audience, from deep technical discussions to high-level value justifications and education for customers\n\nProficiency and practical experience with at least one proof assistant (e.g., Lean, Coq, Isabelle, Agda) and a strong foundation in formal methods and mathematical logic\n\nProficiency in one or more programming languages (e.g., Python, C++, Matlab, etc.)\n\nPreferred Qualifications\nMS or PhD in Computer Science, Mathematics, or a related field\n\nLean 4 expertise or strong fluency in another proof assistant\n\nExperience applying formal verification methods to real-world industrial or commercial systems\n\nProven track record of high-caliber research demonstrated by publications, patents, or software contributions\n\nContributions to open-source projects or development of software tools in the field\n\nWhat We Offer\nUnlimited PTO\n\n401(k) matching\n\n100% employer-paid health, vision, and dental benefits for employees and 50% coverage for dependents. Harmonic offers varied health coverage options to select what is best for you and your family.\n\nHealth Savings Account (HSA) available for qualifying health plans\n\nEqual Opportunity Statement\nHarmonic is committed to diversity and inclusivity in the workplace.
