* Description:

The Information Systems Security Engineer (ISSE) conducts and reviews technical security assessments of computing environments to identify vulnerabilities, ensure compliance with Information Assurance (IA) standards, and recommend mitigation strategies. The ISSE validates and verifies security requirements and designs, integrating security capabilities into systems, networks, and multi-enclave environments. This role supports architects and developers in applying consistent security policies, builds secure system architectures, and ensures trusted relationships across external systems.

The ISSE contributes to security planning, risk analysis, risk management, and certification activities across the system lifecycle, applying expertise in IA principles, cryptography, authentication, authorization, intrusion detection, contingency planning, configuration management, auditing, and security testing. The role also supports security authorization processes compliant with NSA/CSS NISCAP, DoD RMF, NIST RMF, and related security engineering business practices.

Key Responsibilities:

* Perform or review technical security assessments to identify vulnerabilities and ensure IA compliance.
* Validate, verify, and define system security requirements and designs.
* Design, develop, implement, and integrate IA/security systems and components across networked and multi-enclave environments.
* Embed IA into systems deployed to operational environments.
* Assist architects and developers with applying appropriate information security functionality.
* Support the development and maintenance of secure system architectures.
* Enforce trusted relationships among internal and external systems and architectures.
* Assess and mitigate security threats and risks throughout the program lifecycle.
* Contribute to security planning, assessments, risk analysis, and risk management activities.
* Review Certification and Accreditation (C&A) documentation for completeness and compliance.
* Apply expertise in security engineering domains, including:
* System security design
* Engineering lifecycle processes
* Cross-domain solutions
* COTS/GOTS cryptography
* Identification, authentication, authorization
* Risk management
* Intrusion detection
* Contingency and incident handling
* Configuration and change management
* Auditing
* IA principles (confidentiality, integrity, non‑repudiation, availability, access control)
* Security testing
* Support security authorization activities under NSA/CSS NISCAP, DoD RMF, NIST RMF, and related processes.
* Serve as a security engineering representative on engineering teams for secure system, network, and enclave design and integration.
* Act as the primary security engineering representative for secure architecture and system integration efforts.
* Apply IA policies, procedures, and workforce structures to secure environment design.
* Interact with customers and project team members.
* Support enforcement of trusted external system relationships on behalf of the Government.
* Identify security requirements for handling Government data.
* Design system or network architectures spanning multiple enclaves with differing classification requirements.
* Recommend system‑level solutions to satisfy security requirements.
* Provide expert guidance and evaluate work products of other security engineers.
* Advocate for and recommend improvements to IA policy.
* Collaborate with customers, IT staff, and senior leadership to achieve IA objectives.
* Ensure secure architecture and design for information systems, including programs of record and special‑purpose environments with platform IT interconnectivity.
