Job description

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.

Responsibilities

• Own the Rime web app: Lead our React/TypeScript web presence, transforming it from a codebase that needs work into a high‑performance, scalable application.
• Drive Growth: Build the conversion flows, onboarding experiences, and CTAs that turn casual visitors into power users.
• Master the Data: Architect the analytics pipelines and instrumentation that give us crystal‑clear visibility into the entire user funnel.
• Partner on Strategy: Work side‑by‑side with our growth product manager, marketing, and sales partners to ship work that actually moves the needle.

Qualifications

• Full‑Stack Fluency: Experience in the TypeScript/Node.js ecosystem and can own features from end to end.
• Bias towards Action and Autonomy: You act quickly on insights, preferring to show rather than tell.
• Growth Engineering: You’ve built and optimised signup flows, activation loops, and conversion funnels that drive real results.
• Data‑Driven Execution: You measure, track, and optimise the features you build. Familiarity with A/B testing frameworks and experimentation infrastructure.
• Product Instinct: You prioritise user behaviour and conversion as highly as code quality, building solutions that serve both the user and the business.

Desired Experience

• Experience with growth tooling (Segment, Metronome, Amplitude, Mixpanel, PostHog, or similar).
• Experience at an early‑stage startup.

Benefits & Culture

• Direct ownership of a high‑visibility surface that is central to how Rime grows.
• Collaborate closely with founders, marketing, and sales.
• Meaningful equity upside at an early stage.
• High ownership, high standards, low bureaucracy.
