• Hands-on experience with CI/CD tooling (GitLab CI, Jenkins, Azure DevOps, or GitHub Actions) and at least one SAST/SCA or container scanning tool (e.g., SonarQube, Fortify, Snyk, Trivy, Anchore, Prisma).
• Scripting proficiency (Python, PowerShell, or Bash) and comfort with REST APIs.
• Active, final SECRET security clearance; U.S. citizenship.
• DoD 8140/8570 IAT Level II baseline certification (e.g., Security+ CE, CySA+, GSEC) or ability to obtain within 6 months.

• Ensure applicable pipeline security controls (SAST, dependency scanning, container image scanning, and infrastructure-as-code checks) are implemented in DevSecOps CI/CD/CM pipelines; document the controls for the SSP and capture scan reports in the Evidence Index (RMF Step 3).
• Analyze code and pipeline findings for security weaknesses and verify that mitigation strategies are validated and sustained across the system lifecycle.
• Perform risk identification and IT governance assessments throughout the CI/CD/CM pipeline; brief ISSOs on pipeline risks.
• Support hardened-build verification for development and production systems and ad-hoc scanning requests.
