[Hiring] Senior Oracle DBA at Symbotic

Role Overview

This role focuses on supporting a large-scale database migration and modernization initiative. The primary objective is to transition enterprise databases from legacy infrastructure to modern, supported platforms while upgrading Oracle database versions and ensuring system security, stability, and performance. This is a high-priority, time-sensitive initiative with no new application development—purely infrastructure and database-focused transformation.

• Administer and maintain Oracle databases (10g, 11g, 12c, 19c) in large multi-tenant environments
• Design, build, and configure Oracle database servers across Windows, Linux, and Unix-based systems
• Lead and support enterprise Oracle database migrations to newer versions (19c or higher)
• Ensure database performance for enterprise applications (e.g., GIS, Java, and web-based systems)
• Implement and maintain database security, auditing, and compliance controls
• Support both cloud-based and on-premise database environments
• Configure and manage advanced Oracle features (e.g., Data Guard, RAC, TDE, OEM)
• Perform backup/recovery planning and execution
• Troubleshoot complex database issues and provide expert-level support
• Conduct systems analysis and contribute to technical solution design
• Coordinate implementation of complex systems and assist with data refresh activities
• Identify, assess, and communicate technical risks and mitigation strategies
• Document technical work and ensure effective knowledge transfer
