Job Summary

Rime is a foundation modeling company that builds voice AI for enterprises running customer experiences at scale. Our models are purpose-built for high-volume conversational deployments engineered for the accuracy performance and deployment flexibility that production environments actually demand.

We started from a different premise than the rest of the field: build voice AI for human connection not slop. Before we trained a single model we built our own corpus: full-duplex studio-quality conversational speech of normal people recorded and annotated by linguists. Its why our models are unparalleled in naturalism and its why enterprises pick Rime when pilots need to make it to production.
