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:
- 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
The successful candidate should be comfortable working across multiple areas of enterprise infrastructure, including:
- 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.
