CloudLinux / TuxCare is a remote-first infrastructure and security company. More than 300 engineers build and operate products used by hosting providers, enterprises, and internal service teams worldwide. Our Infrastructure Department runs the platforms behind CloudLinux OS, Imunify, KernelCare, TuxCare ELS, and our engineering systems.We 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.PostgreSQL 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.Your Responsibilities:Own production PostgreSQL reliability: HA design, Patroni, PgBouncer, replication, failover, upgrades, vacuum/bloat control, query tuning, locks, indexes, capacity, backups, PITR, and restore validationImprove disaster recovery and operational evidence: tested restores, documented recovery paths, measurable RTO/RPO targets, runbooks, and safe maintenance plansSupport 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 useAutomate DBA workflows with Ansible, Terraform/OpenTofu, GitLab CI/CD, scripts, and reproducible runbooks for provisioning, grants, backups, restores, health checks, and ownership metadataHelp build DBaaS-style self-service capabilities so engineering teams can request databases, access, credentials, and operational checks with less manual DBA interventionImprove observability and incident response through Grafana, metrics, logs, SLOs, alert rules, Opsgenie routing, and clear communication during production issuesWhat Success Looks Like:PostgreSQL clusters have tested backup and restore paths, useful dashboards, clear ownership, and documented failover proceduresRepeated DBA tickets become automation or self-service workflowsClickHouse operational knowledge is no longer a single-person dependencyDatabase incidents have owners, runbooks, evidence, and measurable recovery pathsProduct and engineering teams get database help faster without sacrificing safety, auditability, or reliabilityWhy CloudLinux?You will work on real production infrastructure used across CloudLinux and TuxCare products. You will have a direct impact on reliability, incident response, developer experience, and operational resilience. You will also work in an AI-assisted engineering culture where automation, documentation, Claude, Codex, and careful human verification are part of the daily operating modelRequirementsWhat We Expect From You:Deep hands-on PostgreSQL experience in business-critical production environments, typically 5+ years or equivalent depthStrong understanding of PostgreSQL internals and operations: MVCC, WAL, transactions, locks, indexes, query planning, replication, autovacuum, bloat, major upgrades, backups, PITR, and restore testingProven experience with highly available databases and the ability to reason about quorum, split-brain risk, failover, rollback, and recoveryStrong Linux and infrastructure fundamentals: systemd, networking, storage, filesystems, CPU/memory/disk bottlenecks, TLS, DNS, firewalls, and root-cause troubleshootingAutomation skills with Ansible and scripting. Terraform/OpenTofu, GitLab CI/CD, and merge-request based delivery are strong advantagesAbility 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 itPractical 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 conclusionsEnglish - upper-intermediate or higher - to ensure clear communication of progress within the teamsNice to Have:ClickHouse operations: replication, Keeper/ZooKeeper, MergeTree engines, distributed DDL, grants, row policies, backups, query troubleshooting, and cluster recoveryMongoDB replica sets and Percona Backup for MongoDBRedis/Sentinel and broker/cache failure modesDatabase observability, SLOs, golden signals, alert tuning, and executable incident runbooksBuilding internal platforms, self-service portals, or DBaaS workflows for engineering teamsBenefitsWhat's in it for you?A focus on professional developmentInteresting and challenging projectsFully remote work with flexible working hours, which allows you to schedule your day and work from any location worldwidePaid 24 days of vacation per year, 10 days of national holidays, and unlimited sick leavesCompensation for private medical insuranceCo-working and gym/sports reimbursementBudget for educationThe opportunity to receive a reward for the most innovative idea that the company can patentBy applying for this position, you agree with CloudLinux Privacy Policy and give us your consent to maintain and process your personal data with this respect.
