You will own the network solutioning of k0rdent AI, the platform for building and operating GPU clouds and AI factories, from metal to model. The role combines research with hands-on, outward-facing work: designing large GPU cluster interconnections and tenant isolation, turning designs into reference architectures, proofs of concept and working code, and presenting to engineers, executives and conference audiences. It is remote, open to candidates based in Europe, with travel of up to 25%.

Key responsibilities

• Design and publish network reference architectures for k0rdent AI, from single racks to multi-thousand-GPU clusters, including InfiniBand and RoCEv2 fabrics, front-end, storage and management networks, and multi-tenant isolation (InfiniBand partitions, VRFs, EVPN-VXLAN, Kubernetes network policy)
• Host and platform networking: Linux NIC/DPU/SuperNIC exposure, Kubernetes CNI, Multus, SR-IOV, RDMA, KubeVirt and virtual machine networking
• Research emerging AI networking technologies, prototype designs in the lab, and present findings internally and externally
• Build and validate proofs of concept with customers and partners, and write automation and tooling (Python, Go, Ansible, Terraform, Kubernetes manifests)
• Run validation and benchmarking of fabrics and host configurations, and turn findings into design guidance
• Act as network subject matter expert in customer discovery and design reviews, work with hardware and networking partners, and present at industry events and run workshops

Required profile

• Bachelor's degree in Computer Science, Electrical Engineering, Telecommunications or a related field, or equivalent practical experience
