Network Engineer
- AI Infrastructure Fabric (IB/Spectrum-X, BGP) Our client is a fast-scaling AI infrastructure operator building out next-generation GPU compute campuses across multiple European countries, supporting some of the largest AI training and inference workloads in the region. They're in the middle of an aggressive multi-site build-out, six deployments across four countries, and need experienced network engineers who can design and operate the high-speed fabric that ties tens of thousands of GPUs together. The Role You'll own the design, build, and operation of the network fabric connecting large-scale GPU clusters, including InfiniBand / NVIDIA Spectrum-X fabrics, plus the BGP routing at the network edge that connects these sites to the wider internet and to each other. This is hands-on, high-stakes infrastructure work: the fabric you build directly determines how efficiently thousands of GPUs can train and serve AI models.

What You'll Do
* Design, deploy, and operate InfiniBand and/or NVIDIA Spectrum-X fabric across multiple GPU cluster deployments
* Own BGP routing and edge network architecture across sites in Germany, the Netherlands, and Spain
* Work directly with platform and facility engineering teams during new site bring-up, ensuring fabric performance meets the demands of GB200/GB300-class GPU hardware
* Troubleshoot fabric-level performance issues affecting distributed training and inference workloads
* Build and maintain network automation to manage fabric configuration at scale
* Participate in an on-call rotation supporting live production fabric across sites What We're Looking For
* Experience with InfiniBand and/or NVIDIA Spectrum-X fabric design and operation at scale
* Strong BGP and EVPN routing expertise, ideally including spine-leaf architectures
* Experience with fabric management tooling (e.g. NVIDIA UFM or equivalent)
* Network automation experience (Python, Ansible, or similar)
* Comfort working in a fast-moving, multi-site build-out environment with tight deadlines
* Prior experience at a hyperscaler, neocloud/GPU-cloud provider, or NVIDIA/Mellanox background is a strong plus. Nice to Have
* Experience with NVIDIA DGX/HGX or GB200/GB300-class platform deployments
* Background supporting AI/ML training or inference infrastructure specifically Why This Role This is a rare opportunity to build fabric-level infrastructure for genuinely frontier-scale AI compute
- tens of thousands of GPUs, exabyte-scale storage, and the newest hardware generation, during a period of hypergrowth, with real ownership over the network architecture from day one. #J-18808-Ljbffr
