Terraform/OpenTofu

Additional Information

Required Previous Experiences: Deep hands-on PostgreSQL experience in business-critical production environments, typically 5+ years or equivalent depth.
Strong understanding of PostgreSQL internals and operations: MVCC, WAL, transactions, locks, indexes, query planning, replication, autovacuum, bloat, major upgrades, backups, PITR, and restore testing.
Proven experience with highly available databases and the ability to reason about quorum, split-brain risk, failover, rollback, and recovery.
Automation skills with Ansible and scripting. Terraform/OpenTofu, GitLab CI/CD, and merge-request based delivery are strong advantages.
Ability to support more than one database engine. You do not need to be a ClickHouse expert on day one, but you must be ready to learn it quickly and take responsibility for it.
Practical use of AI engineering assistants such as Claude and Codex. We expect you to use them to improve speed and quality, while personally verifying generated SQL, commands, scripts, and operational conclusions.
Preferred Qualifications: ClickHouse operations: replication, Keeper/ZooKeeper, MergeTree engines, distributed DDL, grants, row policies, backups, query troubleshooting, and cluster recovery.
MongoDB replica sets and Percona Backup for MongoDB.
Redis/Sentinel and broker/cache failure modes.
Database observability, SLOs, golden signals, alert tuning, and executable incident runbooks.
Building internal platforms, self-service portals, or DBaaS workflows for engineering teams.
