Network Engineer - AI Infrastructure Fabric (IB/Spectrum-X, BGP)

A continuación se detalla todo lo que necesita saber sobre lo que implica esta posibilidad, así como lo que se espera de los solicitantes.
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 RoleYou'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. N
