About The Position

The Data Networking Senior Manager is accountable for reliable, secure, scalable, cost-effective operation of the enterprise data network. The position leads teams responsible for day-to-day management, engineering, lifecycle planning, and continuous improvement across Data Center Core, Internet Edge, cloud connectivity, WAN/SD-WAN, campus LAN, wireless, and network-management platforms. The manager combines people leadership with technical depth to review designs, validate operational decisions, lead major incidents, and ensure engineering work is deliberate, documented, and measurable.

The role owns enterprise network service performance and operational standards, develops engineering staff, oversees incident and change practices, manages projects, programs, budgets, vendors, and carriers, and maintains lifecycle and technical-debt plans. It partners with security, compute, storage, cloud, telecommunications, application, service-management, and business stakeholders to deliver integrated enterprise services and communicate risks and decisions to leadership.

The position is typically office or administrative work and is not substantially exposed to adverse environmental conditions. It involves sitting most of the time and exerting up to 10 lbs. occasionally or negligible weights frequently. The position is not eligible for overtime compensation.

Requirements

• Six years of experience related to the area of assignment.
• Two years of supervisory or management experience.
• Bachelor’s degree in Computer Science or a related field; a combination of post-secondary education and/or job-related experience may substitute for required experience on a year-for-year basis.

Nice To Haves

• Significant experience leading enterprise network engineering and operations in a large, complex environment.
• Strong working knowledge of enterprise routing and switching, including BGP, OSPF, VLANs, segmentation, high availability, QoS, and troubleshooting methodology.
• Practical leadership experience with Cisco Catalyst, Nexus, ACI, enterprise wireless, and network-management/observability platforms.
• Experience operating WAN/SD-WAN, Internet edge services, carrier connectivity, VPN technologies, and resilient cloud connectivity.
• Experience with ITIL-aligned incident, problem, change, service request, configuration, and continual-improvement practices.
• Demonstrated ability to lead major incidents, drive root-cause analysis, and implement sustainable corrective actions.
• Experience managing technical staff, senior/principal engineers, vendors, budgets, service providers, and lifecycle programs.
• Ability to review architectures and implementation plans sufficiently to identify risk, challenge assumptions, and ensure supportability.
• Knowledge of automation and API-driven network operations, such as Python, Ansible, and REST APIs, is strongly preferred.
• Cisco professional-level certification or equivalent demonstrated expertise is preferred; expert-level certification is desirable but not required.

Responsibilities

• Own availability, performance, capacity, reliability, security, scalability, cost-effectiveness, and supportability of the enterprise network across data centers, Internet services, cloud connectivity, WAN/SD-WAN, campus LAN, wireless, and network-management platforms.
• Lead day-to-day network operations, engineering, lifecycle planning, and continuous improvement using service metrics and trend data to identify risk and improve reliability.
• Lead, coach, and develop engineering staff; establish accountability and ownership, delegate effectively, build succession depth, and support certification and technical growth.
• Establish operating standards for monitoring, incident response, problem management, change control, service requests, maintenance, configuration management, documentation, and vendor escalation.
• Review operational metrics and use trend data to drive root-cause analysis and corrective action.
• Lead critical network incidents, ensuring rapid triage, clear ownership, escalation, communication, service restoration, post-incident review, and documented corrective actions.
• Manage network projects and programs, including scope, milestones, task ownership, dependencies, schedules, budgets, risks, acceptance criteria, leadership reporting, documentation, and operational handoff.
• Provide leadership for Cisco data center networking, including ACI/Nexus environments, core routing and switching, segmentation, redundancy, high availability, inter-data-center connectivity, and integration with compute, storage, firewall, and virtualization platforms.
• Require peer review, implementation and rollback planning, validation, testing, and documentation for material and high-risk network changes.
• Maintain current network diagrams, standards, runbooks, IP/VLAN documentation, configuration standards, support procedures, escalation paths, inventory records, CMDB information, and recovery procedures.
• Oversee reliable Internet connectivity and cloud network access, including BGP/ECMP design, DDoS readiness, edge resiliency, routing policy, addressing, NAT where applicable, carrier diversity, and cloud connectivity to platforms such as Azure and AWS.
• Lead WAN and SD-WAN services, including branch connectivity, routing, path diversity, failover, carrier coordination, backup services, and performance management across critical sites.
• Monitor WAN route and tunnel stability, latency, packet loss, utilization, capacity, and failover performance and ensure corrective action is taken when needed.
• Ensure stable, secure, and supportable campus switching and enterprise wireless services, including access/distribution architectures, WLAN controllers, access points, segmentation, QoS, authentication dependencies, and capacity planning.
• Maintain hardware and software lifecycle plans, code currency, vendor defect awareness, vulnerability coordination, end-of-support/end-of-life tracking, refresh roadmaps, and technical-debt reduction plans.
• Drive standardization and automation where they reduce operational risk and manual effort.
• Hold carriers, OEMs, managed-service providers, and integrators accountable for service performance, incident ownership, contractual obligations, escalation, SLA attainment, and corrective actions.
• Develop resource, maintenance, lifecycle, and project forecasts; manage operating and capital expenditures within approved budgets; identify budget variances and opportunities to simplify services, reduce cost, and improve reliability.
• Partner with Network Security, Compute, Storage, Cloud, Telecommunications, Security/GRC, application teams, service management, and business stakeholders to coordinate dependencies, risks, and operational handoffs.
