About the role

We are looking for a pragmatic, Software Engineer to own the productionization of our research pipelines. This is an implementation-heavy role designed for an engineer who can take a nascent research idea and build the robust, scalable machinery required to prove it at scale within our cloud infrastructure. Pipeline Engineering: Build and manage end-to-end ML pipelines (ETL and automated evaluation) that are the bedrock of our RL research.

What they're looking for

  • BS in Computer Science, a related technical field, or equivalent industry experience
  • 2+ years of relevant industry experience
  • Expert-level Python skills and a disciplined approach to software engineering (testing, versioning, and modular design)
  • Experience building and managing end-to-end ML pipelines in a production or research-intensive environment
  • Full-stack ML experience: Comfortable moving from data engineering to model debugging
  • Experience refactoring research-grade code into high-quality, scalable production packages
More about this role

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 Lean 4 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.
