Information System Security Engineer

The Information System Security Engineer (ISSE) serves as a dedicated, customer-facing cybersecurity engineering consultant supporting organizational ISSMs, ISSOs, Mission Partners, system owners, architects, and development teams. The ISSE provides expert security architecture and Risk Management Framework (RMF) guidance for on-premises, cloud-hosted, legacy, and modernizing systems throughout the System Development Lifecycle (SDLC). The ISSE helps customers understand cybersecurity requirements and develop actionable technical solutions that implement controls, remediate vulnerabilities, and improve system security before or following formal assessment.

Responsibilities Include:

• Serve as the embedded security engineering expert for Mission Partners, ISSMs, ISSOs, system owners, architects, and development teams.
• Provide security engineering support throughout the SDLC, including requirements gathering, design reviews, sprint planning, modernization, implementation, and production.
• Translate RMF, NIST SP 800-53, DoD cybersecurity policy, and other governance requirements into actionable, threat-informed engineering solutions.
• Conduct in-depth security architecture and design reviews for new and existing systems.
• Analyze network architectures, cloud-native architectures, applications, APIs, microservices, containers, serverless functions, interfaces, and data flows to identify security weaknesses.
• Collaborate with architects and developers to identify achievable security controls and reduce compliance friction before formal assessment.
• Engineer and document vulnerability mitigation strategies and provide technical consultation supporting POA&M corrective actions.
• Develop solutions that reduce system attack surface and improve resiliency without unnecessarily compromising mission capability.
• Translate security requirements into specific technical implementation activities such as MFA, database encryption, secure network zoning, and related controls.
• Apply DoD STIGs, SRGs, and PPSM guidance to system engineering activities.
• Use security telemetry and findings from SIEM, vulnerability scanning, and EDR technologies to recommend architectural and engineering improvements.
• Provide technical mentorship and guidance to ISSMs, ISSOs, developers, and system owners.
• Present cybersecurity risks, architectural findings, mitigation strategies, and recommendations to technical personnel and Government leadership.
• Document customer interactions, systems supported, issues addressed, and technical recommendations as required.
