ECS is seeking a Network Security Engineer (CDAP) - Senior to support the Army National Guard (ARNG) Enterprise Network Operations and Cybersecurity Support (ENOCS) program. In this role, the engineer supports Task 3 - Cybersecurity Operations Support by designing, implementing, and optimizing network security monitoring and analytic capabilities within the Cybersecurity Data Analytics Platform (CDAP). The position contributes directly to Defensive Cyberspace Operations - Internal Defensive Measures (DCO-IDM) across the DoDIN-Army-NG area of responsibility by engineering data ingestion from network sensors and boundary devices, improving detection logic, and coordinating with SOC, CTIC, defensive cyber, and infrastructure teams to strengthen ARNG network defense operations.
This role operates in a mission environment that delivers DoDIN services and cyber defense for more than 120,000 users and approximately 141,000 endpoints across roughly 2,800 sites in 54 states and territories, supporting Title 10 and Title 32 missions, mobilization readiness, domestic emergency response, and classified and unclassified operations. The Network Security Engineer (CDAP) - Senior helps improve visibility and response across environments that include USIEM analytics, EDR, IDS/IPS, firewall technologies, cross domain services, and SIPRNet and NIPRNet-connected operations, while coordinating with organizations such as the NETCOM Global Cyber Center and DISA DCDC to advance continuous monitoring, threat-informed defense, and RMF-aligned cybersecurity outcomes.
Please Note: This position is contingent upon contract award.
Responsibilities
  • Design and implement network security monitoring and analytics capabilities within CDAP to improve threat visibility across ARNG classified and unclassified network environments.
  • Engineer and maintain data ingestion pipelines from network sensors, firewalls, IDS/IPS, and boundary protection devices to support centralized security analytics and continuous monitoring.
  • Develop, tune, and validate correlation rules and detection logic to improve detection fidelity, reduce false positives, and strengthen DCO-IDM operations across DoDIN-connected environments.
  • Support configuration hardening, performance optimization, and validation testing of network security technologies in alignment with DoD and ARNG cybersecurity policy and RMF objectives.
  • Coordinate with SOC, CTIC, defensive cyber, and infrastructure teams to refine detections, improve analytic coverage, and support cyber incident identification and response workflows.
  • Leverage integrated USIEM, C2C, and DLP analytics approaches described for Task 3 to enhance centralized visibility and machine-speed response across the ARNG enterprise.
  • Coordinate with USIEM engineers and related cybersecurity teams to improve enabling data sources, support MITRE ATT&CK-based analytic development, and strengthen enterprise detection outcomes.
  • Support monitoring and defense of environments spanning approximately 141,000 endpoints across 2,800 sites in 54 states and territories, helping protect mission operations tied to Title 10, Title 32, and domestic emergency response requirements.
  • Contribute to cybersecurity operations performed in coordination with the NETCOM Global Cyber Center and DISA DCDC, ensuring analytic and monitoring capabilities support 24x7x365 ARNG cyber defense objectives.
