· Conduct code reviews, static analysis, and vulnerability remediation to ensure compliance with secure coding standards and program security requirements.

· Support configuration management, CI/CD pipelines, and test automation for AFSIM capabilities delivered under government contracts.

· Collaborate with government engineers, analysts, and other contractors to capture requirements, refine use cases, and translate them into verified, validated simulation capabilities.

· Prepare and deliver technical documentation, test reports, user guides, and briefing materials in accordance with contract deliverable requirements (CDRLs).
