Job Summary

We are seeking a Senior Data Centre Network Engineer to join our Global Network Services team, operating and modernising the data centre networks that underpin 7h4vbS worldwide. Our data centre estate today runs a traditional, vPC-based architecture. The mission for this role is to take us to a modern Clos / spine-leaf fabric, and to help build out the AI/ML fabrics that 8ZcjRF'7 growth in AI and storage now demands. This is a deep technical role for a data centre networking expert who can keep the current environment reliable while leading its transformation end to end — from target design, through a phased brownfield-to-greenfield migration, to day-two operations of the new fabric.

The ideal candidate pairs strong, hands-on data centre networking fundamentals with proven experience designing and migrating to spine-leaf fabrics (VXLAN / BGP EVPN), and brings — or is eager to build — the automation, infrastructure-as-code and AI-fabric skills that define where the field is heading. You will be a senior technical voice on the team, mentoring others and setting the standard for engineering quality as we shift from manual, repetitive operations toward codified, repeatable engineering.

Job Responsibilites

• Operate and modernise the data centre estate — keep today's traditional, vPC-based data centre network reliable, secure and performant while leading its evolution toward a modern fabric.

• Design and lead the migration to a Clos / spine-leaf fabric — own the target VXLAN / BGP EVPN design (distributed anycast gateway, symmetric/asymmetric IRB, multi-tenant VRFs) and drive a phased brownfield-to-greenfield migration, extensible to VXLAN multi-site / DCI across regions.

• Build out AI/ML and storage back-end fabrics — design and deliver lossless Ethernet fabrics (RoCEv2, PFC, ECN/DCQCN) for GPU/compute and high-performance storage as 7h4vbS scales its AI infrastructure.

• Own routing and the control plane — operate enterprise routing today and engineer the BGP (eBGP/iBGP) underlay and EVPN overlay of the target fabric, with ECMP, data centre and internet edge, and inter-site connectivity.

• Operate the switching estate — run Cisco Nexus (NX-OS) / ACI, Arista EOS or Juniper platforms — vPC/MLAG, VLANs, trunking, LACP and first-hop redundancy today, transitioning to leaf, spine and border-leaf roles.

• Deliver builds, refreshes and migrations — produce designs, interconnect and cabling matrices and cutover plans; coordinate with vendors and installation partners through delivery, including high-radix 100G/400G optics.

• Resolve escalated operational issues (Tier 3/4) — act as the senior escalation point for complex incidents across the control plane, data plane and physical layer, driving packet-level root-cause analysis and permanent resolution.

• Drive change through structured change control — plan, risk-assess and execute changes with appropriate testing, validation and rollback, which is critical through the migration.

• Maintain fabric health through observability — use fabric controllers (Cisco ND, Arista CloudVision, Juniper Apstra) and streaming telemetry to detect, diagnose and pre-empt issues before they impact users.

• Codify operations — partner with automation/SRE colleagues to move recurring work from manual operations toward infrastructure as code and network as code.

• Set the engineering standard — contribute standards, runbooks and documentation, and mentor junior engineers as a technical multiplier across the team.

Job Requirements

Data Centre Networking (Foundations)

Strong, hands-on expertise in enterprise data centre networking: Layer 2 / Layer 3 design, VLANs, trunking, vPC/MLAG, spanning tree and first-hop redundancy (HSRP/VRRP).

Hands-on experience operating Cisco Nexus (NX-OS) and/or ACI, Arista EOS, or Juniper at enterprise scale.

Proven troubleshooting across the control plane, data plane and physical infrastructure.

Fabric Modernisation (the mission)

Proven experience designing and/or migrating to Clos / spine-leaf fabrics with VXLAN and BGP EVPN (distributed anycast gateway, symmetric/asymmetric IRB, multi-tenant VRFs) — you do not need to have run our estate, but you should have taken an environment to a fabric before, or be ready to.

Ability to plan and execute a phased brownfield-to-greenfield migration from a traditional architecture, with minimal disruption.

JKDXcbyp VR — or a strong appetite to build — AI/ML fabric design (lossless Ethernet, RoCEv2) and high-performance storage networking.

Routing & Control Plane

Expert BGP (eBGP/iBGP): route policy, path selection, redistribution and address-family design, for both traditional routing and an EVPN overlay.

Strong grasp of ECMP, OSPF (underlay) and data centre / internet edge design, including working with service providers on connectivity and troubleshooting.

General

Significant hands-on experience (typically 8+ years) in enterprise network engineering and operations — including a senior or lead technical role — with substantial time in data centre environments.

Demonstrated ownership of complex, high-impact infrastructure in a global environment, including delivery through planned maintenance windows and migration cutovers.

Strong troubleshooting discipline and structured incident-resolution skills under pressure.

Excellent communication skills, with the ability to work across regions and mentor others.
