Senior Network Engineer

Senior Network Engineer

We are seeking an experienced Senior Network Engineer to design, implement, support, and troubleshoot complex enterprise network infrastructure. This role is highly hands-on and requires someone who can operate at both the architecture/design level and the implementation level. The ideal candidate has extensive experience with enterprise routing and switching, SD-WAN, wireless, data center connectivity, campus networks, and network architecture. This individual should be comfortable taking ownership of a network deployment from initial design and cabling requirements through implementation, troubleshooting, documentation, and ongoing support.

Travel is required for office, campus, data center, and infrastructure deployment projects.

Key Responsibilities

• Design, architect, implement, and support enterprise network infrastructure across offices, campuses, and data center environments.
• Lead network deployments for new offices, buildings, and campus locations from the ground up.
• Develop network architecture, topology, IP addressing, routing, switching, wireless, security, and connectivity designs.
• Configure, deploy, and troubleshoot Cisco routers, switches, wireless infrastructure, and SD-WAN solutions.
• Design and manage complex routing environments using BGP, OSPF, and EIGRP, with particular emphasis on BGP.
• Develop and implement resilient network architectures with appropriate redundancy, high availability, and failover.
• Work with data center and colocation providers, including Equinix, to establish and manage connectivity.
• Configure and manage Equinix Fabric connections and related network connectivity.
• Evaluate and validate physical network infrastructure, including structured cabling, fiber, copper, patch panels, racks, and network demarcation points.
• Provide technical leadership during network moves, office openings, infrastructure upgrades, and network refresh projects.
• Troubleshoot complex network issues across Layer 1–Layer 3 and beyond, including routing, switching, wireless, WAN, SD-WAN, and connectivity issues.
• Use packet-analysis and troubleshooting tools such as Wireshark to identify and resolve complex network problems.
• Develop detailed network topology diagrams, architecture diagrams, implementation plans, and operational documentation.
• Establish and document network standards, procedures, and processes.
• Participate in network monitoring, performance analysis, capacity planning, and infrastructure optimization.
• Collaborate with security, systems, cloud, facilities, and other technology teams on infrastructure projects.
• Participate in after-hours maintenance windows and provide escalation support when required.

Required Qualifications

• 10+ years' enterprise networking experience in a Senior Network Engineer or Network Architect capacity.
• Strong hands-on experience with Cisco networking equipment, including routers and switches.
• Extensive knowledge of dynamic routing protocols, particularly BGP, OSPF, and EIGRP.
• Strong understanding of TCP/IP, VLANs, STP, EtherChannel, HSRP/VRRP, DHCP, DNS, NAT, and other core networking technologies.
• Proven experience designing and implementing enterprise network architectures.
• Hands-on experience with SD-WAN technologies.
• Hands-on experience designing, deploying, and troubleshooting enterprise Wi-Fi/wireless networks.
• Experience designing and implementing networks for new offices, buildings, and campus environments from the ground up.
• Extensive knowledge of structured cabling, including fiber and copper, cable standards, patching, terminations, rack layouts, and physical network infrastructure.
• Experience working with Equinix and establishing/managing Equinix Fabric connections.
• Excellent network troubleshooting and analytical skills.
• Strong experience using Wireshark and other network diagnostic tools.
• Ability to create clear and accurate network topology and architecture diagrams.
• Strong technical documentation and communication skills.
• Willingness and ability to travel as required.

Preferred Qualifications

• Experience with Palo Alto firewalls and enterprise security architectures.
• Experience with Grafana, SolarWinds, or other network monitoring and observability platforms.
• Experience with network automation and infrastructure-as-code concepts.
• Programming or scripting experience, particularly Python, is a plus.
• Experience developing network automation scripts and tools.
• Experience integrating monitoring, alerting, and automation platforms.
• Experience with data center networking and interconnects.
• Experience with cloud networking and hybrid infrastructure.
• Relevant Cisco certifications such as CCNP or CCIE are highly desirable.

Technical Skills

• Routing & Switching: BGP, OSPF, EIGRP, VLANs, STP, HSRP/VRRP, Layer 2/Layer 3, WAN
• Network Infrastructure: Cisco routers/switches, SD-WAN, enterprise Wi-Fi, campus networks, data center networking
• Connectivity: Equinix, Equinix Fabric, Internet/WAN circuits, data center interconnects
• Security: Palo Alto firewalls, network segmentation, firewall routing and connectivity
• Physical Infrastructure: Fiber and copper cabling, structured cabling, patch panels, racks, demarcation, physical network design
• Monitoring & Automation: SolarWinds, Grafana, network monitoring/observability, Python/scripting, network automation
• Troubleshooting & Documentation: Wireshark, packet analysis, performance troubleshooting, network topology/architecture diagrams, technical documentation

What We're Looking For

We are looking for someone who can own a network project from beginning to end. This is not simply a configuration or support role. The ideal engineer can walk into a new building, assess the physical infrastructure and cabling, determine network requirements, develop the architecture, design the topology, coordinate circuits and connectivity, configure the Cisco infrastructure, establish SD-WAN and wireless, troubleshoot issues during deployment, and produce the documentation required to operate the environment afterward. You should be equally comfortable designing the architecture on a whiteboard, configuring a Cisco switch, tracing a fiber connection, analyzing a Wireshark capture, troubleshooting BGP, and documenting the final topology. Travel to offices, campuses, data centers, and other infrastructure locations will be required.
