What you will do

• Own production PostgreSQL reliability, including HA design, Patroni, PgBouncer, replication, failover, upgrades, query tuning, backups, PITR, and restore validation.
• Improve disaster recovery through tested restores, documented recovery paths, measurable RTO/RPO targets, runbooks, and safe maintenance plans.
• Support ClickHouse, MongoDB, and Redis operations by troubleshooting incidents, reviewing access and data-safety changes, and improving monitoring.
• Automate provisioning, grants, backups, restores, health checks, and ownership metadata using Ansible, Terraform/OpenTofu, GitLab CI/CD, scripts, and reproducible runbooks.
• Build DBaaS-style self-service workflows that reduce manual DBA intervention for database, access, credential, and operational requests.
• Improve observability and incident response with Grafana, metrics, logs, SLOs, alert rules, Opsgenie routing, and clear production communication.

• Experience with MongoDB replica sets, Percona Backup for MongoDB, Linux, networking, storage, filesystems, TLS, DNS, firewalls, and root-cause troubleshooting.
• Automation skills with Ansible and scripting; Terraform/OpenTofu and GitLab CI/CD experience are advantageous.
• Upper-intermediate English or higher is required for clear communication within engineering teams.

Nice to have

• ClickHouse operations, including replication, Keeper/ZooKeeper, MergeTree, distributed DDL, grants, row policies, backups, query troubleshooting, and cluster recovery.
• Redis/Sentinel, database observability, SLOs, golden signals, alert tuning, and executable incident runbooks.
