Senior Database Administrator (Oracle EBS & Multi-Platform)

As a Senior Database Administrator, you will serve as the primary technical expert responsible for the stability, optimization, and security of our core Oracle Database infrastructure and our Oracle E-Business Suite (EBS) 11i legacy environment.

Because this enterprise environment operates under strict change-freeze and non-patching constraints, you will focus heavily on compensating security controls, network isolation, and proactive mitigation to protect vulnerable systems without altering core database code.

While Oracle EBS and Oracle Database administration are the primary requirements for this role, additional experience managing MySQL, PostgreSQL, and MS SQL Server is a highly valued asset.

Primary Focus: Oracle EBS 11i & Oracle Database Administration

• Legacy Environments & Compensating Security: Enforce strict security postures for non-patchable systems (e.g., Oracle EBS 11i) through virtual patching, database firewalls, and host-level security configurations.
• Network Isolation: Architect and maintain tight network segregation, ensuring Oracle database access is strictly restricted to authorized application servers and admin jump boxes.
• Advanced Monitoring & Auditing: Implement and oversee deep database auditing (monitoring SYS, SYSTEM, and APPS accounts) to detect and alert on anomalous activity or exploit attempts in real time.
• EBS 11i Maintenance: Troubleshoot, clone, and support the database backend for Oracle EBS 11i environments while ensuring absolute stability and zero disruption to legacy custom code.
• Performance & Query Tuning: Monitor system health, code complex SQL/PL-SQL queries, and optimize index structures and query plans to maximize speed without relying on version upgrades.
• High Availability & Recovery: Maintain, document, and test rigorous backup strategies (e.g., Oracle RMAN) and disaster recovery (DR) plans to ensure rapid recovery options.
