## About the role

Cartesia builds real-time multimodal intelligence: fast, state-of-the-art voice models and the products that make them useful. We started as a research lab, pioneered the state space model architecture, and now we're bringing that research to customers through intuitive tools for creating, testing, and shipping with voice.

## What they're looking for

- Experience building and operating customer-facing software in production, ideally at a high-growth startup. We care more about what you've shipped than strict years of experience
- Strong product instincts: you think in customer outcomes, usability, quality, and developer experience, and you have opinions on what to build and why
- Full-stack range and the ability to own a product surface across frontend, backend, APIs, data, and operational concerns
- Fluent use of coding agents and a habit of keeping pace with the frontier
- Clear communication with technical and non-technical audiences, strong cross-functional partnership, and a sharp presence in product and design reviews
