The role combines enterprise security architecture with practical delivery responsibilities, including integration of security controls, security assessment support, Authorization to Operate activities, vulnerability remediation, POA&M management, and participation in application development, integration, and testing.\nThis position is best suited to a hands-on security architect who can work directly with software engineers, testers, DevSecOps personnel, system owners, and federal security stakeholders. It is not a governance-only or policy-only architecture role.\nKey Responsibilities:\nDesign and maintain enterprise security architecture for assigned ICAM applications and services.\n\nTranslate DHS asecurity requirements into implementable architecture and technical controls.\n\nContribute to or oversee secure application and configuration development.\n\nIntegrate security controls into application, infrastructure, cloud, and DevSecOps environments.\n\nLead or support system security assessments and technical control validation.\n\nDevelop, update, or support documentation required for Authorization to Operate activities.\n\nIdentify and remediate vulnerabilities within DHS-required timeframes.\n\nDevelop and manage remediation actions and POA&M items when findings cannot be immediately resolved.\n\nWork with development and testing teams to ensure security requirements are incorporated throughout the SDLC.\n\nSupport development, integration, testing, and release activities within the assigned workstream.\n\nReview technical designs, code, configurations, security scan results, and implementation evidence.\n\nHelp ensure medium- and high-severity static and dynamic application vulnerabilities are resolved before production release.\n\nSupport incident investigation, root-cause analysis, and corrective action when security issues affect production systems.\n\nMaintain architecture, security, assessment, and remediation documentation.\n\nRequired Qualifications:\nExperience designing or maintaining enterprise application or system security architecture.\n\nExperience integrating cybersecurity controls into software, cloud, infrastructure, or DevSecOps environments.\n\nExperience supporting security assessments or authorization activities.\n\nExperience identifying, documenting, and remediating technical vulnerabilities.\n\nExperience developing or managing POA&M remediation actions.\n\nAbility to work with software engineering and testing teams throughout the SDLC.\n\nAbility to interpret security requirements and translate them into technical controls.\n\nAbility to obtain and maintain favorable DHS EOD, suitability, and required system access.\n\nPreferred Qualifications:\nPrior DHS or federal civilian agency clearance or experience.\n\nExperience supporting federal ATO packages or NIST Risk Management Framework activities.\n\nExperience with ICAM, IAM, PIV, PKI, PAM, SSO, OAuth, OIDC, or access-control systems.\n\nExperience with AWS, Azure, hybrid-cloud, or on-premises federal environments.\n\nExperience with secure CI/CD pipelines and automated security gates.\n\nExperience with SonarQube, Jenkins, GitHub Enterprise, Splunk, container security, STIGs, or hardened images.\n\nCISSP, CSSLP, CCSP, AWS/Azure security certification, or comparable security credential.","description_format":"text","description_chars":3448,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United
