Job description

We are hiring a Principal Network Engineer to serve as a hands-on technical leader and subject-matter expert for a large-scale enterprise network environment. This role will lead the design and modernization of data center, WAN, SD-WAN, cloud-connectivity, and multisite network solutions. The engineer will translate high-level business or technical concepts into detailed high-level and low-level designs, implementation plans, diagrams, standards, and presentations. The position will lead architecture involving BGP, VXLAN, spine-leaf fabrics, underlay/overlay topologies, Cisco Nexus 9K or comparable data-center platforms, GCP connectivity, and the evolving Equinix backbone. The Principal Engineer will also evaluate emerging technologies, identify improvements to scalability, resiliency, security, and cost, and provide technical direction to senior engineers. This remains a hands-on role involving implementation, complex troubleshooting, cutovers, limited travel, and on-call participation.

Must Haves

• Principal, lead, Architect, or highly advanced senior-level enterprise networking experience
• Expert-level routing/switching. BGP and dynamic routing are hard requirements.
• Cisco (specifically Nexus 9k) is heavily preferred; Arista, Juniper, Aruba, and Palo Alto are acceptable substitutes
• Proven enterprise network architecture and design experience, including creation of high-level and low-level diagrams
• Ability to translate loosely defined requirements into complete technical designs, implementation plans, standards, and documentation
• Demonstrated experience designing and deploying VXLAN fabrics
• Strong understanding of spine-leaf architecture and underlay/overlay network topologies
• Experience managing and troubleshooting large-scale WAN and multisite connectivity supporting stores, distribution centers, campuses, or other distributed locations
• Working knowledge of cloud networking and hybrid connectivity (GCP Preferred), including cloud routers, virtual networks/VPCs, routing, and connectivity between on-premises infrastructure and cloud platforms
• Willingness to participate in an on-call rotation, respond to PagerDuty escalations, and support occasional after-hours cutovers or maintenance

Nice to Haves

• CCNP Enterprise, CCNP Routing and Switching, or equivalent certification
• Network automation experience using Python, Ansible, Terraform, APIs, or Postman
• Equinix Fabric, Network Edge, or virtual-backbone experience
• Fortinet/FortiGate experience, including SD-WAN, switching, centralized policy management, or Fortinet certifications
• Experience supporting low-latency, high-traffic retail or omnichannel environments
• Experience mentoring or providing technical directions to network engineers, particularly during complex troubleshooting and implementation work
• Prior team-lead or supervisory experience, ideally 1–3 years directing engineers or technical resources
• Cloud-routing and hybrid-connectivity experience (GCP Preferred)
• Experience designing and supporting zero-trust, least-privilege, segmentation, or secure-access architectures
