Responsibilities
•Own production PostgreSQL reliability, including HA design, Patroni, PgBouncer, replication, failover, upgrades, vacuum and bloat control, query tuning, locks, indexes, capacity, backups, PITR, and restore validation
•Improve disaster recovery and operational evidence through tested restores, documented recovery paths, measurable RTO/RPO targets, runbooks, and safe maintenance plans
•Support ClickHouse, MongoDB, and Redis by troubleshooting incidents, reviewing access and data-safety changes, improving monitoring, and learning existing production ClickHouse patterns
•Automate DBA workflows with Ansible, Terraform/OpenTofu, GitLab CI/CD, scripts, and reproducible runbooks for provisioning, grants, backups, restores, health checks, and ownership metadata
•Help build DBaaS-style self-service capabilities for database, access, credential, and operational-check requests with less manual DBA intervention
•Improve observability and incident response through Grafana, metrics, logs, SLOs, alert rules, Opsgenie routing, and clear communication during production issues
Requirements
•Deep hands-on PostgreSQL experience in business-critical production environments, typically 5+ years or equivalent depth
•Understand PostgreSQL internals and operations, including MVCC, WAL, transactions, locks, indexes, query planning, replication, autovacuum, bloat, major upgrades, backups, PITR, and restore testing
•Proven experience with highly available databases and ability to reason about quorum, split-brain risk, failover, rollback, and recovery
•Experience with MongoDB replica sets and Percona Backup for MongoDB
•Strong Linux and infrastructure fundamentals, including systemd, networking, storage, filesystems, CPU/memory/disk bottlenecks, TLS, DNS, firewalls, and root-cause troubleshooting
•Automation skills with Ansible and scripting
•Ability to support multiple database engines and learn ClickHouse quickly
•Use AI engineering assistants such as Claude and Codex, and personally verify generated SQL, commands, scripts, and operational conclusions
•Upper-intermediate English or higher
Nice to have
•Terraform/OpenTofu, GitLab CI/CD, merge-request based delivery, ClickHouse operations, Redis/Sentinel, broker/cache failure modes, database observability, SLOs, golden signals, alert tuning, executable incident runbooks, internal platforms, self-service portals, and DBaaS workflows
Conditions

•24 paid vacation days per year, 10 national holidays, and unlimited sick leave
•Compensation for private medical insurance
•Co-working and gym/sports reimbursement
