ppWe are hiring a Senior Database Reliability Engineer to join the Infrastructure DBA cell. This is a hands-on production ownership role, not a narrow ticket-processing DBA position. You will keep critical database services reliable, automate repeated work, support engineering teams, and reduce single-person dependency in our PostgreSQL, ClickHouse, MongoDB, and Redis operations. /p pPostgreSQL is the main requirement. ClickHouse experience is a strong plus, but it is not a day-one blocker. We need a senior engineer with enough database, Linux, automation, and incident-response depth to learn our ClickHouse environment quickly and operate it safely. /p h3Your Responsibilities /h3 ul liOwn production PostgreSQL reliability: HA design, Patroni, PgBouncer, replication, failover, upgrades, vacuum/bloat control, query tuning, locks, indexes, capacity, backups, PITR, and restore validation. /li liImprove disaster recovery and operational evidence: tested restores, documented recovery paths, measurable RTO/RPO targets, runbooks, and safe maintenance plans. /li liSupport the wider database estate: ClickHouse, MongoDB, and Redis. You will troubleshoot incidents, review access and data-safety changes, improve monitoring, and learn the production ClickHouse patterns already in use. /li liAutomate DBA workflows with Ansible, Terraform/OpenTofu, GitLab CI/CD, scripts, and reproducible runbooks for provisioning, grants, backups, restores, health checks, and ownership metadata. /li liHelp build DBaaS-style self-service capabilities so engineering teams can request databases, access, credentials, and operational checks with less manual DBA intervention. /li liImprove observability and incident response through Grafana, metrics, logs, SLOs, alert rules, Opsgenie routing, and clear communication during production issues.



/li /ul h3What Success Looks Like /h3 ul liPostgreSQL clusters have tested backup and restore paths, useful dashboards, clear ownership, and documented failover procedures. /li liRepeated DBA tickets become automation or self-service workflows. /li liClickHouse operational knowledge is no longer a single-person dependency. /li liDatabase incidents have owners, runbooks, evidence, and measurable recovery paths. /li liProduct and engineering teams get database help faster without sacrificing safety, auditability, or reliability. /li /ul h3Why Us /h3 pYou will work on real production infrastructure used across products. /p pYou will have a direct impact on reliability, incident response, developer experience, and operational resilience. /p pYou will also work in an AI-assisted engineering culture where automation, documentation, Claude, Codex, and careful human verification are part of the daily operating model. /p h3Requirements /h3 h3What We Expect From You /h3 ul liDeep hands-on PostgreSQL experience in business-critical production environments, typically 5+ years or equivalent depth. /li liStrong understanding of PostgreSQL internals and operations: MVCC, WAL, transactions, locks, indexes, query planning, replication, autovacuum, bloat, major upgrades, backups, PITR, and restore testing. /li liProven experience with highly available databases and the ability to reason about quorum, split-brain risk, failover, rollback, and recovery. /li liStrong Linux and infrastructure fundamentals: systemd, networking, storage, filesystems, CPU/memory/disk bottlenecks, TLS, DNS,



firewalls, and root-cause troubleshooting. /li liAutomation skills with Ansible and scripting. Terraform/OpenTofu, GitLab CI/CD, and merge-request based delivery are strong advantages. /li liAbility 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. /li liPractical 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. /li liEnglish - upper-intermediate or higher - to ensure clear communication of progress within the teams. /li /ul h3Nice to Have /h3 ul liClickHouse operations: replication, Keeper/ZooKeeper, MergeTree engines, distributed DDL, grants, row policies, backups, query troubleshooting, and cluster recovery. /li liMongoDB replica sets and Percona Backup for MongoDB. /li liRedis/Sentinel and broker/cache failure modes. /li liDatabase observability, SLOs, golden signals, alert tuning, and executable incident runbooks. /li liBuilding internal platforms, self-service portals, or DBaaS workflows for engineering teams. /li /ul h3Benefits /h3 ul liA focus on professional development. /li liInteresting and challenging projects. /li liFully remote work with versátil working hours, which allows you to schedule your day and work from any location worldwide. /li liPaid 24 days of vacation per year, 10 days of national holidays, and unlimited sick leaves. /li liCompensation for private medical insurance. /li liCo-working and gym/sports reimbursement. /li liBudget for education. /li liThe opportunity to receive a reward for the most innovative idea that the company can patent. /li /ul /p #J-18808-Ljbffr
