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.
What You'll Do
- Design and deliver fullstack features that power UI Studio’s generative platform capabilities
- Architect and implement scalable services and user-facing workflows using TypeScript across frontend and backend (Node.js)
- Integrate LLM-powered coding agents into product workflows, including tool use, planning loops, evaluation loops, and multi-step orchestration
- Contribute to search and retrieval infrastructure, including vector-based search systems, indexing strategies, and relevance optimization
- Design, ship, and operate distributed systems deployed via containerized infrastructure such as Docker and Kubernetes
- Take end-to-end ownership of well-scoped systems and features, from technical design and implementation through deployment, monitoring, and operational support
- Improve internal APIs, platform primitives, and developer tooling to create intuitive and scalable platform experiences
- Uphold strong engineering standards through automated testing, observability, documentation, and continuous delivery practices
Who You Are
- You have professional experience building production systems with TypeScript and Node.js, and you’re comfortable contributing across the full stack
- You have hands-on experience building or meaningfully integrating LLM-powered coding agents, including tool integrations and multi-step workflows
- You understand search and retrieval design patterns, such as vector search systems, Elasticsearch, and indexing strategies
- You have experience designing and operating distributed systems and deploying services using containerized tooling such as Docker and Kubernetes
- You demonstrate strong software engineering fundamentals and can independently ship well-scoped features end-to-end
- You think in systems — considering reliability, scalability, observability, and maintainability in your designs
- You communicate clearly in writing and produce structured, actionable technical documentation
- You care about developer experience and have experience building tools or platforms used by other engineers
Where You'll Be
- This role is based in Stockholm
- We offer you the flexibility to work where you work best! There will be some in person meetings, but still allows for flexibility to work from home.
