Company

hirify.global is hiring for an infrastructure-focused database reliability role supporting production database operations and engineering teams.

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 with Ansible, Terraform/OpenTofu, GitLab CI/CD, scripts, and reproducible runbooks.
• Build DBaaS-style self-service capabilities for database requests, access, credentials, and operational checks.
• Improve observability and incident response with Grafana, metrics, logs, SLOs, alert rules, Opsgenie routing, and clear production communications.

Requirements

• Senior-level, hands-on PostgreSQL experience in business-critical production environments, typically 5+ years or equivalent depth.
• Strong knowledge of PostgreSQL internals and operations, including MVCC, WAL, transactions, locks, indexes, query planning, replication, autovacuum, bloat, upgrades, backups, PITR, and restore testing.
• Experience with highly available databases and failover, quorum, split-brain risk, rollback, and recovery.
• Strong Linux and infrastructure fundamentals covering systemd, networking, storage, filesystems, resource bottlenecks, TLS, DNS, firewalls, and root-cause troubleshooting.
• Automation experience with Ansible and scripting; Terraform/OpenTofu, GitLab CI/CD, and merge-request-based delivery are advantageous.
• English at upper-intermediate level or higher is required for clear team communication. Ability to learn and operate multiple database engines, including ClickHouse, is also required.

Nice to have

• ClickHouse operations experience with 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 or cache failure modes.
• Database observability, SLOs, golden signals, alert tuning, and executable incident runbooks.
• Experience building internal platforms, self-service portals, or DBaaS workflows.
