Job description

About The Company

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.

About The Role

We are looking for a talented Software Engineer to bridge the gap between our AI research and product development teams. This role involves working closely with research scientists to understand their discoveries and advancements in AI, and then applying this knowledge to develop robust, scalable software for real-world applications. The ideal candidate should be passionate about AI technology and experienced in software development.

Key Responsibilities

• Collaborate with AI research scientists to understand and implement state‑of‑the‑art AI algorithms.
• Develop and maintain software that incorporates AI technologies into practical applications and products.
