• Assist with financial‑data validation and troubleshooting.
• Develop technical documentation, operating procedures, test documentation, and knowledge articles.
• Participate in code reviews and peer testing.
• 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.
