Backend Engineer, Music

About the Role

In the Music Mission, we build the tools and services that enable creators to express themselves, promote their work, and connect with fans. Discovery Mode is a key promotional tool that helps artists, labels, and licensors grow their audience while maintaining a high-quality listener experience.

We are looking for a Backend focused engineer to join the OASIS team. OASIS builds and operates the systems that power promotion delivery and optimization within Discovery Mode. Our work ensures that promotional content isn't just surfaced, but is intelligently allocated by balancing complex, competing objectives across our entire ecosystem.

The team is distributed and highly collaborative, working closely with Personalization (PZN) to serve high-quality promotion signals. You'll be part of a small, impactful group of engineers across data and machine learning, owning a core piece of infrastructure that enables promotion delivery at scale.

What You'll Do

• Own and evolve backend systems that deliver promotion scores to personalization systems (PZN)
• Build and maintain services that support promotion allocation and delivery at scale
• Collaborate closely with machine learning engineers and data engineers to improve signal quality and system performance
• Contribute to system design decisions that impact a critical part of Spotify's discovery ecosystem
• Improve reliability, scalability, and observability of existing infrastructure
• Partner with cross-functional teams
