About the team: The Release Team oversees the safe, continuous delivery of ClickHouse Cloud, a managed database platform running tens of thousands of ClickHouse clusters. They handle upgrades, maintenance, internal tooling, and act as the final safeguard when issues arise.
About the role: This position is a balanced mix of operational execution and software development. Responsibilities include coordinating and executing upgrades across tens of thousands of clusters, resolving edge cases, and maintaining cluster health. Simultaneously, you’ll build and refine systems to automate and improve future rollouts. Ideal for those who enjoy both writing playbooks and executing them, including the challenging parts.
What you'll do:
Plan and execute rolling upgrades across tens of thousands of ClickHouse clusters, ensuring safety, correctness, and minimal customer impact.
Own the full release pipeline: from pre-upgrade validation and staged rollouts to post-upgrade monitoring and incident response.
Investigate and resolve production issues as part of a regular on-call rotation, including snowflake clusters and edge cases that automation can't yet handle.
Build and improve internal tooling and automation for reliable, repeatable large-scale database operations.
Collaborate with core database and cloud infrastructure teams to address operational pain points and turn them into solved problems.
Support and educate other engineering teams using internal tools.
About you:
At least 5+ years of experience operating stateful distributed systems in production, such as databases, message queues, or storage systems.
Hands-on experience running upgrades or maintenance operations on live production data stores, at scale.
Strong production debugging skills; comfortable digging into unfamiliar systems under pressure.
Experience with cloud infrastructure (AWS, Azure, or GCP) and Kubernetes.
Software development experience in Go (or strong experience in another language with a willingness to learn).
Experience with ClickHouse (preferred, as a user, operator, or contributor).
