This position will lead the design, capacity planning, installation, configuration, clustering, performance tuning, and monitoring of large-scale Oracle and MongoDB deployments. In addition, the role provides consultative support to development teams on database architecture, design, development best practices, and performance optimization — driving improvements in scalability, reliability, and operational efficiency.

  • Provide expert-level troubleshooting and root cause analysis for database-related incidents.
  • Mentor development and data warehouse teams on advanced SQL, PL/SQL, and MongoDB query optimization.
  • Continually improve DBA standards, procedures, and automation practices.
  • Provide on-call support and occasional travel as required.
  • Bachelor's or Master’s degree in Information Systems, Computer Science or a related field.

  • 5+ years of supporting developers with application design, query tuning, and schema optimization.
  • 3+ years of hands-on MongoDB administration experience (replica sets, sharding, backups, monitoring).
  • 3+ years of experience with Linux administration (shell scripting, system tuning, automation).
  • Experience with automation frameworks (Ansible, BitBucket, Terraform, or similar).
  • Experience with database monitoring and observability tools (OEM, SolarWinds/DPA, PMM, DataDog, Grafana).
  • Exposure to cloud-native environments (AWS, Azure, OCI, or GCP).
  • Familiarity with DevOps/CI/CD pipelines for database changes.
