About the company

A global AI cloud provider building a full-stack platform that takes developers and enterprises from data and model training through to production deployment, without the cost of in-house AI/ML infrastructure.

The company runs large-scale GPU compute, storage and networking across R&D hubs in Europe, the UK, North America and Israel, with a team of more than 1,500 people, hundreds of them engineers.

Responsibilities

• Design and evolve CLOS/leaf-spine data center fabrics for high-throughput, low-latency GPU workloads, and own routing and switching deployment and lifecycle management in production.
• Plan and validate network testing, including vendor evaluation and benchmarking, and maintain design documentation, standards and operational procedures.
• Troubleshoot complex issues across the TCP/IPv4/v6 stack in distributed environments and tune traffic engineering, ECMP and load balancing for efficient resource use.
• Operate MPLS-based technologies such as L3 VPNs and segment routing, automate network operations, and work with hardware, systems and software teams to integrate networking with compute and storage.

Requirements

• Expert-level routing and switching knowledge for service provider and data center networks (CCIE/JNCIE or equivalent), covering MPLS, BGP, IS-IS, segment routing (SR-MPLS, SRv6), L3 MPLS VPNs and ECMP-based balancing.
• Strong background in Ethernet switching, VXLAN and cloud overlay networking, plus proven experience designing and documenting large-scale architectures and validating vendor solutions through testing strategies.
• Solid grasp of network hardware architecture, QoS and packet processing pipelines, with hands-on work on equipment from vendors such as Juniper, Arista, Huawei and Mellanox, and strong TCP/IPv4/v6 troubleshooting in CLOS environments.
• Working proficiency in English; on-call rotation and collaboration with globally distributed teams are part of the role.
