The Information Systems Security Engineer (ISSE) serves as a key technical cybersecurity professional supporting our US Army customer and the Next Generation Command and Control (NGC2) modernization initiatives. In this role, you will partner closely with Assistant Program Managers (APMs), Product Managers (PdMs), and engineering teams to embed security‑by‑design across modernized tactical software baselines, containerized applications, and secure hybrid cloud/on‑prem architectures. The ISSE ensures modernization efforts maintain a robust, resilient, and defensible security posture against evolving tactical threats.
Responsibilities:
Program Support & Collaboration
Partner with APMs, PdMs, lead systems engineers, and cybersecurity personnel to execute the program’s cybersecurity strategy.
Provide proactive technical consultation to evaluate proposed designs, architectures, and software configurations early in the lifecycle to minimize security risk.
Cybersecurity Documentation & Artifacts
Develop, review, and maintain core program cybersecurity documentation such as the Program Protection Plan (PPP), Cybersecurity Strategy (CSS), System Security Plans (SSP), and technical cyber architecture diagrams.
Modern Architecture & Zero Trust Support
Contribute to the design and engineering of secure, resilient architectures across hybrid cloud (IL5/IL6), virtualized, and tactical edge environments.
Integrate Zero Trust principles, access control mechanisms, encryption approaches, and fault‑tolerant strategies into system designs.
Secure Engineering & Automation
Promote secure software engineering practices to reduce flaws, bugs, and weaknesses.
Collaborate with DevSecOps teams to implement automated security controls, container vulnerability scanning, and compliance‑as‑code within CI/CD pipelines.
Support automation of Windows and Linux system hardening efforts.
Vulnerability Management & Compliance Verification
Conduct and analyze ACAS/NESSUS scans, DISA STIG/SRG compliance checks, and static/dynamic source code vulnerability assessments.
Assist in developing improved automated vulnerability management and patching processes.
Governance & Remediation
Represent Cybersecurity interests on Configuration Control/Review Boards (CCB/CRB).
Coordinate with engineering, vendor, and contractor teams to address vulnerabilities, communicate remediation steps, and manage residual risk.
Qualifications:
Required:
Active DoD Secret clearance, with ability to obtain and maintain a Top Secret (TS).
Bachelor’s degree in Cybersecurity, Systems Engineering, Computer Science, or related technical field - An additional 6 years of DoD cybersecurity experience may substitute for the degree.
5 years of hands‑on engineering experience in cybersecurity, secure systems design, or related role.
DoD 8140/8570 IASAE Level II certification (CASP+, CISSP, or CSSLP).
Desired:
Active DoD TS clearance.
Familiarity with Army Systems Acquisition processes, milestone decision points, and associated cybersecurity artifact requirements.
Ability to align technical solutions with Army program needs and support program‑level cybersecurity strategy.
Agile & DevSecOps Frameworks: Practical experience working within Agile/SAFe development frameworks. Understanding of secure software development lifecycles, CI/CD automated pipeline security, and containerization.
Architecture & Engineering: Hands-on experience with secure cloud (Azure and AWS GovCloud Impact Level 5/6 environments), virtualized platforms (VMware, Hyper-V), and on-premise tactical system architectures. Ability to translate complex security controls into technical, implementable requirements.
Tactical Domain Expertise: Technical understanding of Army Mission Command (MC) / Command and Control (C2) architectures and tactical network environments. Experience securing systems within Army Warfighting Functions (WfF) and transitioning legacy systems to modernized NGC2 capabilities.
Networking & Security Design: Solid understanding of traditional, cloud, and tactical networking concepts (TCP/IP, VLANs, routing, firewalls, VPNs) across the Integrated Tactical Network (ITN). Experience with endpoint detection and response (EDR) tools, automation scripting (Windows/Linux), and Security Orchestration, Automation, and Response (SOAR).
Risk Management Framework (RMF): Strong working knowledge of NIST SP 800-53 security controls, DoDI 8510.01 Risk Management Framework (RMF) for DoD Information Technology, and AR 25-2 Army Cybersecurity. Fluent in navigating the DoD Authority to Operate (ATO) lifecycle via eMASS and conducting residual risk assessments.
