The Experimentation and Learning team (SEAL) sits within the Surfaces Foundation product area in the Personalization mission. This team builds the experimentation and learning infrastructure for Spotify Surfaces — powering how we test, evaluate, and ship personalized experiences across Home and beyond. By creating a unified, agent-driven experimentation ecosystem, we enable teams to go from a raw hypothesis to a fully configured, running experiment in minutes instead of days.

Own and evolve the core experimentation service, building agentic workflows that automate experiment setup, configuration, and validation across multiple backend systems

Design and maintain API-first orchestration layers that coordinate across experimentation and content delivery systems

Build and integrate LLM-driven workflows into robust, production-ready infrastructure, including planner, generator, and validator architectural patterns

Define and uphold SLOs and SLAs for experimentation infrastructure, contributing to a strong culture of reliability and operational excellence

Partner closely with content, feature, and platform teams to scale automated experimentation patterns across a growing range of surfaces and configurations

Identify, diagnose, and resolve bottlenecks in experiment orchestration to ensure fast and reliable workflows

Collaborate across squads to continuously improve how experimentation and evaluation are delivered across Spotify Surfaces
