Fullstack Engineer - Generative UI Platform

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.
We’re looking for a Fullstack Engineer who is strong across backend systems and confident building high-quality frontend experiences — to help scale the platform’s technical foundations and AI-native capabilities. You’ll play a meaningful role in shaping architecture, evolving core systems, and delivering reliable, developer-facing platform functionality used across Spotify.
