Job Description The Network Engineer will serve as a technical lead for the design, implementation, optimization, and maintenance of secure enterprise network infrastructure. Beyond traditional routing and switching, this role heavily focuses on advanced network security and Zero Trust enforcement. As a general focus area, the engineer will champion initiatives related to endpoint compliance, network access control (such as Comply to Connect / C2C frameworks), and application micro-segmentation (leveraging tools like Cisco Secure Workload / CSW). This role ensures rigorous dynamic security policies and secure application data flows across highly complex, mission-critical Department of War (DoW) networks. Design, deploy, configure, and maintain enterprise network infrastructure, including routers, switches, firewalls, and load balancers across globally distributed environments. Engineer and sustain network access control and endpoint compliance architectures, ensuring secure, policy-driven device authentication across the enterprise. Develop and integrate advanced micro-segmentation, application dependency mapping, and zero-trust workload protection strategies within data centers and multi-cloud environments. Perform advanced troubleshooting and root cause analysis for complex network performance and connectivity issues, spanning from OSI Layer 2/3 routing protocols (BGP, OSPF) to application-layer workload policies. Collaborate closely with cybersecurity and systems engineering teams to ensure network architectures comply with DoD STIGs and support secure, authorized data flows. Develop and maintain comprehensive network documentation, including architecture diagrams, data flow maps, and Standard Operating Procedures (SOPs). Evaluate and test emerging network technologies, firmware updates, and security patches prior to enterprise deployment. Deploy, configure, and maintain Cisco Secure Workload for application dependency mapping, micro-segmentation, and zero-trust policy enforcement across data centers and multi-cloud environments. Develop and maintain comprehensive network documentation, including architecture diagrams, data flow maps, and Standard Operating Procedures (SOPs). Implement Comply to Connect (C2C) architectures to enforce endpoint compliance, device profiling, network access control (NAC), and automated remediation.
