Job description

About the Role (Job Purpose)

The Network Engineering Team is responsible for designing, deploying, and operating front‑end networking services that support both internal management platforms and customer‑facing cloud infrastructure. This includes high‑speed Ethernet data center fabrics, internet transit, WAN/long‑haul connectivity, and data center networking.

What You'll Be Doing (Responsibilities)

• Design, deploy, and operate high‑speed Ethernet‑based front‑end networks (data‑center fabrics, management networks, inference traffic paths, storage connectivity)
• Work with deployment teams to ensure BOMs are correct and fit for purpose, focusing on optics, cabling, and hardware selection
• Provide input into DC layout, rack elevations, and reference architectures to ensure front‑end networks are implemented correctly and scalably
• Troubleshoot performance and connectivity issues on Ethernet front‑end networks, including routing, optics, and long‑haul circuits
• Automate deployment, initial stand‑up, and day‑to‑day operations of multi‑vendor Ethernet hardware and platforms
• Design, implement, and support WAN and long‑haul infrastructure (carrier circuits, DCI, internet transit)
• Collaborate with Architecture and Operations teams to maintain high reliability, observability, and operational efficiency across front‑end networks

About You (Skills / Qualifications / Experience)

• Proven experience designing, deploying, and operating high‑speed Ethernet networks, including VLAN, LACP, MLAG, BGP, OSPF, EVPN, and VXLAN
• Strong knowledge of WAN and long‑haul technologies: MPLS, BGP, IPsec, GRE, SD‑WAN, carrier Ethernet, and associated routing protocols
• Solid understanding of data‑center networking topologies and front‑end/infrastructure best practices
• Strong Python or Bash scripting skills for automation and tooling
• Strong optics and hardware knowledge for BOM design, cabling standards, and troubleshooting
• Experience working in fast‑paced operational environments with a focus on reliability and automation

Nice to Have

• Hands‑on experience with Arista (EOS) and/or Nokia networking platforms
• Experience with large‑scale DCI, long‑haul optical transport, or carrier circuit management
• Familiarity with storage networking over Ethernet and shared storage connectivity
• Experience with network automation frameworks, validation tooling, or observability platforms (streaming telemetry, Prometheus, Grafana)
• Prior exposure to AI or hyperscale infrastructure environments
