Senior Network Engineer

Role Summary 

The Senior Network Engineer designs, implements, and maintainsa 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. 

Key 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. 

Required Qualifications AND SKILLS 

• 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. 

• 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. 

• Strong experience with SolarWinds (NPM/NTA) or comparable monitoring platforms, and packet-capture analysis (Wireshark). 

• Hands-on experience with F5 BIG-IP/LTM administration and troubleshooting, plus solid working knowledge of Cisco ISE, Infoblox DDI, and Palo Alto firewalls sufficient to partner effectively with security engineering. 

• Demonstrated ability to lead technical workstreams within larger projects, including data center or SD-WAN initiatives. 

• Strong analytical, troubleshooting, and root-cause-analysis skills for complex, multi-layered network issues. 

• Excellent communication skills, with the ability to translate technical detail for both technical and non-technical audiences. 

• Comfortable managing vendor and MSP relationships for equipment delivery and escalations. 

• Experience with PKI/certificate lifecycle management. 

• Familiarity with infrastructure-as-code and automation tooling (Ansible, Python, Terraform). 

• Experience with Azure or AWS networking at a design/implementation level. 

• CCNP required; progress toward or possession of CCIE strongly preferred.
