About the Work Unit: Vanderbilt University Information Technology is a human-centric organization that advances our university by delivering innovative solutions and frictionless experiences through collaboration. Key Functions and Expected Performance: Network Design & Delivery Designs and implements network solutions across large campus, data center, and cloud-connected environments using established architectures and standards to deliver scalable and reliable connectivity. Leads the delivery of complex network initiatives by coordinating technical work, dependencies, and implementation activities to ensure successful and timely outcomes. Designs and optimizes routing, switching, segmentation, and authentication services using established designs and configuration standards to ensure secure and efficient traffic flow. Designs and optimizes wireless and high-performance network environments, including research and high-throughput data flows, to maintain performance, capacity, and reliability. Contributes to the design and improvement of automation and delivery workflows by applying scripting, APIs, and tooling to increase efficiency and reduce manual effort in network configuration and deployment. Analysis & Problem Resolution Leads technical response for complex and cross-domain network incidents using monitoring data, logs, and diagnostic tools to restore service and stabilize network performance. Conducts root cause analysis by evaluating network behavior across systems and environments and driving corrective actions that reduce recurrence and improve reliability. Acts as an escalation point for high-impact or ambiguous issues by providing technical direction and coordinating resolution across teams to ensure timely service restoration. Identifies patterns in recurring issues and improve operational practices, tooling, and workflows to reduce incident volume and enhance network reliability over time. Performance Engineering & Capacity Planning Performs advanced performance analysis and capacity planning by evaluating network behavior and utilization to ensure infrastructure can support current and projected demand. Identifies bottlenecks and systemic limitations by analyzing traffic patterns and performance data to implement targeted improvements that enhance throughput, latency, and user experience. Evaluates the impact of new services, applications, and traffic patterns on shared network platforms and adjust designs to maintain performance and service quality. Uses operational and performance data to inform engineering decisions and implement improvements that reduce recurring issues and improve overall network reliability. Uses data ‑ driven analysis to support informed engineering decisions and reduce reactive work. Standards, Automation & Security Integration Develops and refines technical standards for routing, segmentation, and network security controls. Designs and implements automation solutions for network provisioning and configuration management using scripting, APIs, and tooling to reduce manual effort and improve consistency. Ensures network designs and implementations meet security and access control requirements by applying and validating configurations during deployment to maintain secure network services. Improves engineering practices and documentation by identifying gaps and implementing updates that increase consistency and reduce configuration errors. Collaboration, Influence & Knowledge Sharing Reviews network designs and changes proposed by others by providing constructive feedback focused on scalability, security, and operational readiness to improve implementation quality. Mentors engineers through design discussions, incident reviews, and shared problem-solving to strengthen team capability and technical consistency. Collaborates with security, infrastructure, and application teams to coordinate complex changes and manage cross-team dependencies and risks. Produces clear technical documentation that supports knowledge transfer, troubleshooting, and long-term maintainability of network services.
