Overview

The Senior Oracle/MongoDB Database Administrator (DBA) is a senior-level technical and administrative role responsible for managing mission-critical database environments. 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.

• Implement and maintain database security, user access, and role management.
• Develop and maintain physical data models and enforce database standards.
• Proactively monitor and tune databases for performance, scalability, and reliability.
• Implement robust backup, recovery, and disaster recovery strategies (Oracle RMAN/Data Guard, MongoDB replication/backup).
• Implement archiving solutions and lifecycle management for data retention.
• Analyze and document database infrastructure, hardware, and technology requirements.
• Partner with development teams to review code and design for performance, scalability, and alignment with best practices.
• 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.
