Job Summary

Design, deploy, and operate the network fabric powering a multi-tenant AI cluster, including lossless RDMA-capable Ethernet/InfiniBand, tenant isolation, and day-2 recoverability. Build and manage leaf-spine data center fabrics (BGP, EVPN/VXLAN), automate provisioning and validation with config-as-code, and deliver telemetry to detect congestion and degradation early. Own the office network and support onboarding and troubleshooting end to end.

Location: London

Workplace: Onsite

Employment Type: Full time

Job Function: IT Operations (Systems/Network Admin)

Seniority: Mid level

Key Responsibilities

•Design and operate lossless, RDMA-capable fabrics for GPU compute and storage traffic, including QoS, congestion control, and buffer tuning.
•Build and manage leaf-spine data center fabrics with routed underlay/overlay design (BGP, EVPN/VXLAN).
•Implement per-tenant network isolation across compute, storage, and management planes.
•Automate network provisioning, configuration, and validation using config-as-code practices (e.g., Ansible, Python, NetBox) deployed through CI.
•Create telemetry/observability and troubleshoot performance issues end to end, from optics and cabling to NIC/DPU configuration and host behavior.

Pay and Benefits

Perks:EquityMeal Allowance

Key Requirements

•5+ years operating production data center networks as a network engineer.
•Strong dynamic routing (BGP) plus overlay/encapsulation design and troubleshooting (EVPN/VXLAN).
•Hands-on experience designing and operating leaf-spine / Clos fabric.
•Comfortable with modern data center network OS and the Linux networking stack.
•Practical RDMA fabric experience (lossless Ethernet like RoCEv2 with PFC/ECN/DCQCN tuning or InfiniBand).
