Network Infrastructure Engineer, Global Network Infra (WAN)

The role

You will design, deploy, and operate global wide area network (WAN) infrastructure. This includes activating network circuits, troubleshooting multi-layer connectivity issues, and building automation to scale network operations.

What you will do

• Design, deploy, and support WAN infrastructure across data centers, network PoPs, and cloud connectivity environments.
• Own end-to-end activation and turn-up of network circuits with fiber carriers and cloud service providers.
• Troubleshoot complex network issues across physical, Layer 2, and Layer 3 infrastructure.
• Diagnose and isolate network failures across carrier, cloud provider, and internal infrastructure boundaries.
• Contribute to physical network infrastructure design including port mappings, fiber layouts, and ODFs.
• Monitor network health, circuit utilization, and performance.
• Build automation and tooling to streamline network provisioning and operational workflows.
• Collaborate with network engineering, data center infrastructure, and external service providers.
• Participate in an on-call rotation.

Required qualifications

• Hands-on experience deploying, activating, and troubleshooting WAN circuits with telecommunications carriers, fiber providers, or cloud service providers.
• Strong understanding of networking fundamentals including optical networking, Ethernet, TCP/IP, BGP, and Layer 2/3 connectivity.
• Comfortable debugging network issues from physical fiber connectivity to routing and traffic forwarding.
• Experience working with data center networking, carrier infrastructure, cloud interconnects, or large-scale WAN environments.
• Understanding of physical network infrastructure concepts such as fiber cabling, port mappings, and optical distribution frames.
• Ability to independently investigate ambiguous connectivity problems and isolate root causes.
• Experience with scripting or automation tools.

Nice to have

• Experience building or operating large-scale backbone networks, hyperscale data center networks, or cloud provider interconnect infrastructure.
• Familiarity with optical transport technologies, network telemetry, and advanced troubleshooting of physical network links.
• Experience automating network operations using Python, Go, or infrastructure automation frameworks.
• Experience deploying new network PoPs or supporting large-scale network expansion projects.
• Experience collaborating with carriers, colocation providers, and cloud networking teams on complex connectivity deployments.

Before you apply

• Background checks for applicants will be administered in accordance with applicable law.
