Senior Database Reliability Engineer

About the role

We are looking for a Senior Database Reliability Engineer to own and improve the reliability of our production database services. This hands‑on role spans PostgreSQL, ClickHouse, MongoDB and Redis, with a focus on automation, incident response and reducing single‑person dependencies.

Key responsibilities

• Design and operate high‑availability PostgreSQL clusters (Patroni, PgBouncer, replication, failover, upgrades, vacuum/bloat control, backups, PITR and restore validation).
• Define and test disaster‑recovery procedures, document runbooks and set measurable RTO/RPO targets.
• Troubleshoot incidents across the broader database estate (ClickHouse, MongoDB, Redis) and improve monitoring and access controls.
• Automate DBA workflows using Ansible, Terraform/OpenTofu, GitLab CI/CD and custom scripts for provisioning, grants, backups, restores and health checks.
• Build self‑service DBaaS capabilities so engineering teams can request databases and credentials with minimal manual intervention.
• Enhance observability with Grafana dashboards, metrics, logs, SLOs, alert rules and Opsgenie routing.

Required profile

• 5+ years of hands‑on experience managing PostgreSQL in production environments.
• Deep understanding of PostgreSQL internals (MVCC, WAL, transactions, locks, indexes, query planning, replication, autovacuum, bloat, major upgrades, backups and PITR).
• Strong Linux administration skills and a proven track record of incident response and automation.
• Ability to quickly learn and safely operate ClickHouse, MongoDB and Redis.
