Key Responsibilities

• Develop current-state and target-state network architectures, designs, diagrams, standards, and technical documentation.
• Assess existing network infrastructure and identify performance, capacity, resiliency, security, interoperability, and modernization requirements.
• Translate business, mission, security, and technical requirements into logical and physical network architecture designs.
• Design and document LAN, WAN, WLAN, VPN, remote-access, internet connectivity, and hybrid/cloud network solutions.
• Develop network architecture artifacts, including topology diagrams, data-flow diagrams, interface specifications, architecture views, standards, and design documentation.
• Support network segmentation, routing, switching, load balancing, firewalls, DNS, DHCP, IP addressing, and related infrastructure services.
• Evaluate network technologies and recommend solutions based on security, performance, scalability, interoperability, cost, maintainability, and lifecycle considerations.
• Support cloud and hybrid-cloud connectivity and integration between on-premises and cloud environments.
• Incorporate cybersecurity requirements, Zero Trust principles, access controls, encryption, network segmentation, and applicable federal security requirements into architecture designs.
