Senior Network Engineer

About the role

The Senior Network Engineer designs, implements, and maintains a scalable, secure network infrastructure across our distribution centers, branches, and cloud environments. This role owns troubleshooting, leads meaningful pieces of network projects (data center connectivity, SD-WAN rollouts, capacity expansions), while partnering closely with the security team on network-security integration.

Responsibilities

• Architect, implement, and maintain scalable and secure network infrastructure across Cisco switching/routing, Cisco/Meraki SD-WAN, and Cisco ACI data center fabric.
• Lead diagnosis and resolution of complex network issues, including intermittent connectivity problems, performance bottlenecks, and multi-site routing/switching faults.
• Design and support enterprise wireless architecture across Cisco and Meraki wireless controllers, including RF planning input, policy, and segmentation.
• Own the day-to-day administration and operational health of SolarWinds NPM/NTA, including monitoring coverage, alerting, dashboards, device onboarding, and platform maintenance; use SolarWinds, Wireshark, and related tools for capacity planning and advanced traffic analysis.
• Own configuration standards and version control for network devices, ensuring consistent, secure, and auditable network operations.
• Administer and optimize Infoblox DDI (DNS, DHCP, IPAM) for enterprise-scale environments.
• Partner with the network security to integrate network devices with Cisco ISE, Palo Alto firewalls, and PKI/certificate-based authentication, and to implement segmentation aligned with Zero Trust principles.
• Lead or significantly contribute to network projects such as data center migrations, SD-WAN expansions, and branch network builds, coordinating with IT operations, security, and application teams.
• Direct the relationship with the managed services provider (MSP) for new site builds, escalations, and complex troubleshooting.
• Evaluate emerging network technologies and provide recommendations to management on adoption for future growth.
• Begin introducing automation (Ansible, Python, or similar) to streamline recurring configuration tasks and reduce manual error.
• Support cloud network connectivity for Azure and/or AWS environments (VPN/ExpressRoute/Direct Connect, VNets/VPCs) in partnership with cloud teams.
• Maintain thorough network documentation, diagrams, and runbooks; ensure changes follow change management standards.
• Participate in an on-call rotation, serving as an escalation point above the MSP's first-line support.

Qualifications

• 8-15 years of hands-on experience in enterprise Cisco network infrastructure, including routing, switching, wireless, and SD-WAN.
• Bachelor’s degree in computer science, Information Systems, or a related discipline.
• CCNP required; progress toward or possession of CCIE strongly preferred.

Skills

• Deep working knowledge of TCP/IP, BGP, OSPF, MPLS, DMVPN, QoS, and policy-based routing.
• Proven expertise with Cisco SD-WAN, Meraki, Cisco ACI (or comparable data center fabric), and Cisco/Meraki wireless.
