Software Engineer, Growth - Rime Ai

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. It's why our models are unparalleled in naturalism, and it's why enterprises pick Rime when pilots need to make it to production.

Role Overview

We're hiring a Software Engineer to own Rime's API growth. You'll take the lead on a React-based web app refining the vision of the codebase, building engagement and funnel features, and making it a reliable platform for our PLG business. You'll also work with data tooling to give the business visibility into what's working. This role sits at the intersection of frontend craft, growth engineering, and backend API work, and is a direct lever on how Rime acquires and converts customers.

  Experience at an early-stage startup.
