Remote Senior 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.

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.

We’re looking for a Senior Fullstack Engineer who is genuinely fullstack — strong across backend systems and confident building high-quality frontend experiences — to help scale the platform’s architecture and AI-native capabilities. You’ll shape core technical decisions, lead complex initiatives end-to-end, and elevate engineering standards across the team.

• 
  

  Design and deliver fullstack features that power UI Studio’s generative platform capabilities

  
  


• 
  

  Architect and implement scalable services and user-facing workflows across frontend (Typescript/Node.js) and backend (Node.js & Java)

  
  


• 
  

  Lead the integration of LLM-powered coding agents into product workflows, including tool use, planning loops, evaluation loops, and multi-step orchestration

  
  


• 
  

  Drive search and retrieval architecture, including vector-based search systems, indexing strategies, and relevance optimization

  
  


• 
  

  Design, ship, and operate distributed systems deployed via containerized infrastructure (e.g., Docker, Kubernetes)

  
  


• 
  

  Take end-to-end ownership of complex systems and features, from technical design and implementation through deployment, monitoring, and operational excellence

  
  


• 
  

  Improve internal APIs, platform primitives, and developer tooling to create intuitive, scalable platform experiences

  
  


• 
  

  Partner closely with product, design, QA, and fellow engineers to deliver high-impact AI-native capabilities used across Spotify

  
  

Who You Are

• 
  

  You have 7+ years of experience building and operating production systems, with deep experience in TypeScript, Node.js and Java

• 
  

  You have experience building or integrating LLM-powered systems, including agent workflows, tool integrations, and multi-step orchestration

  
  


• 
  

  You understand search and retrieval patterns such as vector search systems, Elasticsearch, and indexing strategies

  
  


• 
  

  You have designed and operated distributed systems in cloud environments and deployed services using containerized tooling such as Docker and Kubernetes

  
  


• 
  

  You think in systems, considering scalability, observability, reliability, and long-term maintainability in your designs

  
  


• 
  

  You can independently lead well-scoped initiatives and provide technical guidance to other engineers

  
  


• 
  

  You communicate clearly in writing and produce thoughtful technical documentation

  
  


• 
  

  You care about raising the engineering bar and contributing to a collaborative, inclusive team culture
