• Apply Test-Driven Development and automated testing (Selenium/JUnit, Playwright for modern web) integrated into CI/CD; support functional, integration, and end-to-end testing of AI and non-AI systems; document model assumptions, outputs, model cards, and validation evidence
• Ensure compliance with technical, security, accessibility (Section 508), configuration-management, and release standards in coordination with the agency IT office
• Serve as the engagement's dedicated security resource: support Security Assessment & Authorization (SA&A / RMF) - SSP inputs and POA&M remediation - perform continuous monitoring, and coordinate with the agency Security Operations Center (SOC) on vulnerability reviews and incident response
