Podsumowanie oferty

We are hiring a Senior Database Reliability Engineer to join the Infrastructure DBA cell focused on hands-on production ownership. The role involves ensuring reliability of critical database services including PostgreSQL, automating workflows, supporting engineering teams, and managing databases like ClickHouse, MongoDB, and Redis. The position demands improving observability, incident response, and disaster recovery processes to enhance operational resilience.

Wymagania

Deep hands-on experience with PostgreSQL in business-critical production environments, typically 5+ years.
Strong understanding of 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 concepts like quorum, split-brain risk, failover, rollback, and recovery.
Strong Linux and infrastructure fundamentals: systemd, networking, storage, filesystems, CPU/memory/disk bottlenecks, TLS, DNS, firewalls, and root-cause troubleshooting.
Automation skills with Ansible and scripting; Terraform/OpenTofu, GitLab CI/CD, and merge-request based delivery are advantages.
Ability to support more than one database engine; willing to learn ClickHouse quickly and take responsibility.
Practical use of AI engineering assistants such as Claude and Codex for improving speed and quality of SQL, commands, scripts, and operational conclusions.
English proficiency: upper-intermediate or higher for effective communication.

Nice to have:

ClickHouse operations including 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.
Experience building internal platforms, self-service portals, or DBaaS workflows for engineering teams.

Obowiązki

Own production PostgreSQL reliability: HA design, Patroni, PgBouncer, replication, failover, upgrades, vacuum/bloat control, query tuning, locks, indexes, capacity, backups, PITR, and restore validation.
Improve disaster recovery and operational evidence: tested restores, documented recovery paths, measurable RTO/RPO targets, runbooks, and safe maintenance plans.
Support the wider database estate: ClickHouse, MongoDB, and Redis by troubleshooting incidents, reviewing access and data-safety changes, and improving monitoring.
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 engineering teams to request databases, access, credentials, and operational checks with less manual DBA intervention.
Improve observability and incident response through Grafana, metrics, logs, SLOs, alert rules, and Opsgenie routing; maintain clear communication during production issues.

Benefity

A focus on professional development.
Interesting and challenging projects.
Fully remote work with flexible working hours.
Paid 24 days of vacation per year, 10 days of national holidays, and unlimited sick leaves.
Compensation for private medical insurance.
Co-working and gym/sports reimbursement.
Budget for education.
Opportunity to receive a reward for the most innovative idea that the company can patent.
