MonggoDB DBA

MongoDB Database Administrator

Install, configure, and administer MongoDB deployments (self-managed and/or managed service) across non-prod and prod environments. Design and operate high availability and disaster recovery solutions (replica sets, multi-region architectures) to meet RPO/RTO targets. Plan, execute, and validate backup/restore strategies (snapshot and logical backups), including regular recovery testing and audit-ready evidence. Monitor cluster health and performance (CPU/memory, disk, connections, replication lag, locks/WT cache behavior, query latency) and implement proactive alerting. Perform performance tuning: index reviews, slow query analysis, query plan reviews, cache and resource sizing, and storage optimization. Manage security controls: authentication/authorization (RBAC), TLS, encryption at rest, key management integrations, network controls, and auditing. Execute patching and version upgrades with minimal downtime, including release notes review, compatibility checks, and rollback plans. Implement and maintain automation for provisioning and configuration management (scripting, IaC, CI/CD hooks) and standardize cluster build patterns. Support sharding operations where applicable (chunk balancing, shard key guidance, resharding planning) in partnership with architects and developers. Troubleshoot incidents and lead database operational response: triage, mitigation, root-cause analysis, and post-incident remediation actions. Capacity planning and cost optimization: forecast growth, scale resources, and right-size clusters based on workload trends. Maintain documentation, runbooks, and operational SOPs; provide guidance to application teams on MongoDB operational best practices.
