• Cross-train on both application and database functions to provide backup coverage.
• Participate in Transition-In knowledge transfer and operational-readiness activities.
• Support future NISC V design, development, testing, integration, and deployment activities.

The FAA specifically requires first- and second-level helpdesk support covering user activation/deactivation, production issues and financial-data validation, in addition to application O&M responsibilities.
