About the Job

Requirements

  • At least 8 years of experience in network engineering, operations, or infrastructure, including senior design and architecture ownership.
  • Deep expertise in Transmission Control Protocol/Internet Protocol (TCP/IP), routing, switching, wireless networking, virtual local area networks (VLANs), Domain Name System (DNS), and Dynamic Host Configuration Protocol (DHCP) at scale.
  • Full-stack network experience across data center, campus, and multi-site environments, including wired and wireless networks.
  • Production experience with Border Gateway Protocol (BGP) and Open Shortest Path First (OSPF), including route policy, redistribution, filtering, and path selection.
  • Hands-on experience with overlay networks, especially Virtual Extensible LAN (VXLAN)/Ethernet VPN (EVPN) fabrics and spine-leaf architectures.
  • Campus local area network (LAN) and enterprise wireless design experience; cloud-managed platforms such as Juniper Mist are preferred in the requirement wording as an ideal fit.
  • Experience designing high availability and redundancy, including BGP/OSPF failover, Hot Standby Router Protocol (HSRP)/Virtual Router Redundancy Protocol (VRRP), and path resiliency.
  • Proven multi-site enterprise network experience.
  • Strong software-defined wide area network (SD-WAN) architecture and implementation experience.
  • Hands-on virtual private network (VPN) experience, including GlobalProtect, IPsec site-to-site VPNs, and remote access.
  • Cloud networking design experience with Amazon Web Services (AWS) and/or Microsoft Azure, including hybrid connectivity and routing.
  • Proficiency with Infrastructure-as-Code (IaC) tools such as Git, Terraform, Ansible, Pulumi, and continuous integration/continuous delivery (CI/CD).
  • Track record of leading complex network projects to completion.
  • Strong operational approach that balances speed and reliability.
  • Ability to lift and move networking equipment weighing approximately 50 pounds.
  • Comfort working in data centers and equipment rooms.
  • Willingness to travel 10–20% for site deployments.
  • Availability to participate in an on-call rotation and occasional after-hours maintenance.

Responsibilities

  • Own network architecture across data center, campus, multi-site, and cloud environments, setting scalable standards and reference designs.
  • Lead new site bring-ups from topology design and capacity planning through production handoff.
  • Architect scalable routing and switching, including route policy, redistribution, and segmentation.
  • Design and operate BGP for internet edge, multi-homing, and cloud interconnects, including peering, filtering, path selection, and failover.
  • Build VXLAN/EVPN fabrics, including spine-leaf architectures, BGP EVPN control plane, virtual tunnel endpoints (VTEPs), Layer 2/Layer 3 virtual network identifiers (VNIs), and data center interconnect (DCI) for scalable segmentation and multi-tenancy.
  • Design and operate campus networks across offices and factory floors, including access, distribution, core versus collapsed core, wired, and wireless networks.
  • Operate cloud-managed wired and wireless networks with Juniper Mist, including Mist AI, Wired Assurance, and WAN Assurance, for AI-driven operations and troubleshooting.
  • Implement SD-WAN and overlay technologies, including Generic Routing Encapsulation (GRE), IPsec, and Secure Access Service Edge (SASE), to connect sites, cloud environments, and remote users.
  • Design highly available connectivity, including VPNs (GlobalProtect, IPsec, and remote access), first-hop redundancy (HSRP/VRRP), and switch clustering.
  • Architect cloud networking across AWS and Azure, including VPC/VNet, transit, peering, hybrid connectivity, and BGP over Direct Connect/ExpressRoute.
  • Drive network automation with IaC for provisioning, configuration, and change management.
  • Set standards for monitoring, observability, documentation, and operational runbooks.
  • Lead root-cause analysis across routing, overlays, wireless, DNS, and performance issues.
  • Manage internet service provider (ISP) and telecommunications relationships for circuits, redundancy, and escalations.
  • Coordinate low-voltage vendors and structured cabling for facility and data center build-outs.
  • Guide connectivity for facility systems, including cameras, access control, and Internet of Things (IoT), as well as corporate Wi-Fi.
  • Mentor IT and infrastructure teammates and review designs and changes.
  • Participate in on-call rotations, incident response, maintenance windows, and improvements to escalation processes.
  • Support Kubernetes and container networking, including Container Network Interface (CNI), ingress, and service networking.

Desired Qualifications

  • Advanced certifications such as CCNP, CCIE, JNCIP/JNCIE, or equivalent.
  • Hands-on experience with Juniper Mist (Mist AI, Wired Assurance, WAN Assurance, and Marvis) for campus operations and AIOps.
  • BGP at scale, including route reflectors, communities, traffic engineering, and multi-provider edge.
  • EVPN/VXLAN fabrics in data center and/or campus environments, including BGP EVPN, symmetric/asymmetric IRB, VRF multi-tenancy, ESI-LAG, and DCI.
  • Route and overlay hardening, including RPKI, prefix filtering, max-prefix limits, and BFD.
  • Experience with multi-vendor fabric platforms and controllers, including Juniper Apstra, Arista CloudVision, and Cisco NX-OS/ACI.
  • Deep experience with Juniper (EX/QFX, SRX, Mist) and Palo Alto firewalls.
  • AWS/Azure networking depth, including VPC, Direct Connect, VPN Gateway, Transit Gateway, and ExpressRoute, with BGP-based hybrid routing.
  • Kubernetes networking, including CNI, ingress, service mesh, and BGP load balancing such as MetalLB/Calico.
  • ISP relationship and circuit-provisioning management at scale.
  • Structured cabling and low-voltage program leadership.
  • Facility systems experience, including cameras, access control, and IoT.
  • Experience designing high-availability, 24/7 production environments.
  • Experience mentoring administrators and engineers, or technical lead experience.
