Fullstack Engineer - Generative UI Platform

StockholmOn-siteFull-time

AI Summary

Fullstack Engineer who builds production-grade backend and frontend features for Spotify's UI Studio platform, including LLM-enabled workflows, vector search, and distributed systems.

About this role

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
