Job summary

Verda is building a European cloud platform and seeks an experienced Database Administrator to own the stateful data layer, including Postgres and ClickHouse clusters. You’ll design, deploy, and operate production-grade storage; implement replication, backups, and zero-downtime migrations; and collaborate with engineering teams to optimize performance while maintaining strong reliability.

You’ll work in a hybrid Helsinki office with a focus on scalable, secure data systems and modern automation

Qualifications

• 5+ years administering production relational databases, with deep hands-on Postgres expertise.
• Strong experience with Postgres replication, high availability, failover, backup and point-in-time recovery.
• Strong experience with analytical databases; ClickHouse in production is a strong plus, and candidates who can demonstrate rapid mastery of complex new technologies are encouraged to apply.
• Track record of database performance tuning - query plans, indexing, schema design, vacuum/merge behavior, resource sizing.
• Experience with on-call rotations and production incident management on the data tier.
• Strong Linux administration and debugging skills.
• Experience with infrastructure automation (Ansible), GitOps, and CI/CD as applied to stateful systems.
• Comfortable designing and executing zero/low-downtime schema changes and major-version upgrades.
• Working knowledge of database observability - metrics, slow-query analysis, and capacity planning (Prometheus, Grafana, or similar).
• Scripting or programming experience (Python, Bash, Go, or similar).
• Strong collaboration and communication skills

Responsibilities

• Own the lifecycle of our stateful data storages - design, deploy, operate, upgrade, and decommission Postgres and ClickHouse clusters in production.
• Run replication, high-availability, and failover for Postgres and ClickHouse (replicated tables, keeper, sharding).
• Design and continuously verify backup and point-in-time recovery procedures across all managed engines, and rehearse restores on a regular cadence.
• Maintain monitoring, alerting, and capacity planning for database workloads, and drive query- and schema-level performance work with the application teams.
• Participate in on-call rotations, lead incident response for data-tier outages, and run blameless post-mortems.
• Plan and execute schema changes, version upgrades, and data migrations with zero or minimal downtime.
• Operate the surrounding key-value and NoSQL stores (Redis-style caches, Mongo, etc.) the platform depends on.
• Develop automation for provisioning, configuration, and routine operations using Ansible, GitOps, and CI/CD workflows.
• Contribute to data-tier standards, runbooks, and operational best practices
