Research Engineer, Technical Lead

At Harmonic, we are building a mathematical reasoning engine that operates with absolute precision. While most AI makes maximum-likelihood guesses, Harmonic's Aristotle uses Lean4 and reinforcement learning to verify its reasoning and results. Following 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.

We are seeking a highly motivated and experienced Research Engineer, Technical Lead to join our Reinforcement Learning & Formal Methods team. The focus of this position will be on leading advancements in mathematical theorem proving using cutting-edge RL techniques. The successful candidate will play a key role in developing research vision and driving execution against research priorities that integrate RL with formal methods to solve complex problems in theorem proving and beyond
