Senior Database Administrator (ClickHouse)

Responsibilities

• Own the reliability and performance of our production ClickHouse clusters, whether self-hosted on Kubernetes or running on managed ClickHouse services.
• Design a standard architecture and tooling that let us grow to dozens of multi-node clusters without the operational work growing at the same pace.
• Manage the whole cluster lifecycle as code: provisioning, configuration, scaling, upgrades, and migrations.
• Build monitoring and alerting that catch problems before users notice them.
• Own backups and disaster recovery, and test restores regularly.
• Plan capacity and keep infrastructure costs under control.
