About the job

Join our dynamic team as a MongoDB Database Engineer where you will be responsible for managing, optimizing, and automating production-grade MongoDB clusters in enterprise environments.

  • Design and maintain robust high availability and disaster recovery strategies
  • Perform backups, restores, upgrades, and patching with minimal or zero downtime
  • Monitor cluster health, replication lag, disk usage, and query performance
  • Diagnose and resolve issues such as slow queries, locking problems, index inefficiencies, and capacity bottlenecks
  • Implement security best practices including:
    • Authentication & authorization (RBAC)
    • TLS / encryption at rest
    • Auditing and access controls
  • Automate MongoDB operations using Ansible, scripts, and CI/CD pipelines
  • Support MongoDB deployments on AWS / Azure / GCP
  • Collaborate closely with application and DevOps teams for schema design and performance optimization
  • Participate in on-call rotations and manage production incidents
  • Maintain thorough operational documentation and runbooks
