Senior Fullstack Engineer – Generative UI Platform

About UI Studio

UI Studio is Spotify's internal generative UI prototyping platform that enables teams to spin up fully functioning replicas of Spotify surfaces — complete with playable music — to explore and pitch new product ideas. What started as a small internal project has evolved into a widely adopted platform, and we're now expanding it into a full generative UI system where teams can prompt for the interfaces they need.

As part of Spotify's Platform mission, we build the technology that enables Spotify to learn quickly and scale easily — creating the infrastructure, tooling, frameworks, and capabilities needed to support our global business and millions of creators and fans.
