Job Title: MongoDB DBA

We are seeking a skilled MongoDB DBA to join our team for a long-term contract role. The ideal candidate will be responsible for the installation, configuration, and administration of MongoDB deployments across non-production and production environments. You will play a crucial role in designing and operating high availability and disaster recovery solutions to meet RPO/RTO targets.

Key Responsibilities:

  • 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.
  • Work with developers on fix validation and identify issues before they occur in production.
  • Ensure the database can scale in production.
