The role maintains and secures a legacy system, embeds security into a modernized cloud platform, supports compliance and authorization, and advises the client on security risks and remediation.

Responsibilities:

• Run automated vulnerability scans of operating systems, databases, and web applications, and lead remediation and patching across Red Hat Enterprise Linux, Oracle, Apache/Tomcat, and Java application components
• Meet contractual remediation timelines for scan and penetration test findings (15 days for critical, 30 for high, 60 for medium, 120 for low), and document Plans of Action and Milestones (POA&Ms) when a timeline cannot be met
• Harden systems against GSA security benchmarks and CIS Level 1 guidelines
• Track end-of-life software, unsupported libraries, and known vulnerabilities, and raise risks early with a recommended path forward
• Support continuous monitoring, log review, and incident response in line with NIST SP 800-61

• Keep security documentation current as legacy capabilities are replaced and retired
• Perform threat modeling for new features, integrations, and architecture decisions
• Embed static and dynamic security testing (such as Snyk and OWASP ZAP) in CI/CD pipelines so every release meets OWASP ASVS with no unresolved medium or high findings
• Review releases for security impact before production, protecting availability
• Advise on secure architecture for the modernized platform, including federated identity, FIPS 140-validated encryption, Zero Trust principles, and software supply chain security
• Prepare security packages for prototype testing and position the new platform to receive an ATO at production deployment
• Provide guidance on public key infrastructure, firewall and network security, internet protocols, and configuration management
• Serve as the client's security point of contact, briefing technical leads and the Project Manager on risks, findings, and remediation progress
