Formal Verification Engineer

About the role

ABOUT HARMONIC

At Harmonic, we believe the future of AI depends on proof. Most AI makes its best guess. Aristotle uses formal methods and reinforcement learning to check its own reasoning and results.

AI agents can write software in seconds, but edge cases and silent bugs still get through. We're building the verification engine to find them before code ships. With support for C and Verilog, Aristotle is built for the hardware and software where failure is expensive.

Backed by some of the world’s most prominent investors, we are intentionally scaling an elite technical team.

ABOUT THE ROLE

We are seeking a Formal Verification Engineer to verify production hardware and software with Aristotle https://aristotle.harmonic.fun/, 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.

KEY RESPONSIBILITIES

- Translate design intent into precise properties, utilize Aristotle intensively to execute formal proofs, and accurately diagnose verification failures.

- Manage project scope and technical risk while maintaining direct, clear communication with customers

- Quickly develop a comprehensive technical understanding of complex production-ready code, often across new or unfamiliar domains

- Identify and analyze the critical properties customer teams need proved, translating business-critical requirements into clear, targeted formal specifications

- Work with the product team to improve Aristotle based on observations in the field

- Travel to customer sites on behalf of the company

MINIMUM QUALIFICATIONS

- BS in Computer Science, Mathematics, a related field, or equivalent industry experience

- Direct experience in hardware verification, software verification, or interactive theorem proving (ITP)

- Demonstrated ability to independently navigate complex concepts, manage risks and deadlines autonomously

- Ability to calibrate communication seamlessly depending on the audience, from deep technical discussions to high-level value justifications and education for customers

- Proficiency 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

- Proficiency in one or more programming languages (e.g., Python, C++, Matlab, etc.)

PREFERRED QUALIFICATIONS

- MS or PhD in Computer Science, Mathematics, or a related field

- Lean 4 expertise or strong fluency in another proof assistant
