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.

Try Aristotle for yourself here!
