Senior Backend Engineer - CI Experience

The CI Experience squad owns the client continuous integration (CI) infrastructure at Spotify. Our mission is to ensure smooth, reliable, and fast integration of code changes across all client repositories. We provide the tooling, documentation, and support that empower client engineers to build, test, and ship confidently.

We are looking for a Backend Infrastructure Engineer with strong experience in building and maintaining backend services that power developer infrastructure. While our current systems handle relatively low traffic, the focus is on reliability, testability, observability, and migration readiness. A key part of this role is to help migrate existing Python-based services to Java, ensuring better alignment with Spotify's monorepo and future automation strategies.

What You’ll Do

• Design, maintain, and evolve backend services supporting our CI infrastructure.
• Improve local development and testing loops to reduce the need for full deployments during validation.
• Drive service migrations (e.g., from Python to Java) and assist in refactoring for scalability and maintainability.
• Implement robust monitoring, logging, and alerting practices for better visibility and debugging.
• Contribute to documentation – especially around service setup, testing, and troubleshooting.
• Collaborate with cross-functional teams to improve developer experience and CI efficiency.
• Help shape our technical roadmap for infrastructure evolution, focusing on automation and resilience.

Who You Are

• Strong backend engineering experience with Java and Python.
• Familiar with microservice architecture, Kubernetes, and caching strategies.
• Experienced in designing maintainable, testable, and observable systems.
• Skilled at writing clear and thorough documentation for services and processes.
• Comfortable working on CI/CD infrastructure, including tools like gRPC/Protobuf, Bazel, and Git.
• Strong understanding of service migrations, from design to execution.
• Collaborative and proactive; able to work autonomously while aligning with broader team goals.
• Bonus: Experience working with Spotify's internal client CI systems or Windows environments.

Where You’ll Be

This role is based in either Stockholm or London. We offer flexible remote work with some in‑person meetings.
