Oracle Database Administrator

Senior DBA

As a Senior DBA, you will play a key role in administering and optimizing relational databases in AWS, with primary focus on Amazon RDS for Oracle, Amazon Aurora PostgreSQL, and Amazon RDS for SQL Server. You will own provisioning, configuration, upgrades, performance, backup and recovery, security, and day-to-day operations. You will also provide leadership and guidance to a team of DBAs and developers, establish cloud database standards and runbooks, and automate health checks and reporting to ensure high performance, availability, and reliability.

Responsibilities

• Administering Amazon RDS databases in AWS. Drive automation, operational excellence, and proactive monitoring through repeatable runbooks and health check reporting.
• Design, deploy, and configure RDS DB instances and Aurora clusters, including instance and storage sizing, subnet and parameter groups, option groups, maintenance windows, Multi-AZ, and read replicas.
• Implement and validate HA and DR strategies, including Multi-AZ, failover configuration, cross-region replication where applicable, and disaster recovery runbooks with defined RTO and RPO.
• Manage automated backups, manual snapshots, retention policies, and cross-region snapshot copies. Perform and document regular restore tests and support Dev, QA, and UAT refreshes using approved methods.
• Use CloudWatch, Performance Insights, and Enhanced Monitoring to diagnose performance issues, analyze wait events and query behavior, and implement tuning actions across Oracle, PostgreSQL, and SQL Server.
• Enforce least-privilege access using IAM and database roles, network isolation using VPC and security groups, encryption at rest using KMS and encryption in transit using TLS. Configure and retain audit and engine logs in CloudWatch Logs as needed.
• Plan and execute minor and major engine upgrades with minimal downtime. Coordinate testing, apply patching within defined maintenance windows, and use blue/green or staged deployment patterns where supported.
• Automate routine tasks using scripting and AWS CLI or SDKs. Partner with DevOps to manage RDS and Aurora changes using infrastructure as code (for example, Terraform or CloudFormation) and integrate database checks into CI/CD pipelines.
• Support database migrations and upgrades using AWS DMS and AWS Schema Conversion Tool when applicable, plus native utilities such as Oracle Data Pump, pg_dump and pg_restore, and SQL Server native backup and restore to S3.
• Implement maintenance routines appropriate for each engine, such as Oracle statistics and maintenance windows, Aurora PostgreSQL vacuum and extension management, and SQL Server index and statistics maintenance and SQL Agent job scheduling, within the capabilities of RDS and Aurora.
• Provide technical leadership to the DBA team, planning and delegating tasks effectively.
• Guide and mentor mid-level DBAs, fostering their professional development and enhancing team capabilities.
• Be the liaison between the database team and other technical and business units, ensuring alignment of database services with organizational goals.
• Work closely with developers, platform teams, and system administrators to optimize database design, resolve issues, and ensure database systems meet business needs.
