Cloud Infrastructure Engineer (GPU/DPU Specialist)

Job Description:

• Multi-GPU systems, GPUDirect RDMA, NCCL/MPI scaling, PCIe vs NVLink tradeoffs
• Hardware offloaded networking (RDMA/RoCEv2, lossless Ethernet (PFC/ECN), VXLAN overlays, NIC/DPU offloads)
• Linux networking and memory model, DMA/IOMMU, PCIe fabric, NUMA locality
• Virtualization and cloud integration (KVM, GPU passthrough/vGPU, SR-IOV, vDPA, Kubernetes/OpenStack integration)
• Performance and security tradeoffs (stateless vs stateful firewalling, datapath placement, observability strategy)

Job Responsibilities:

• Define E2E architecture for GPU compute and high-performance networking using hardware offload (NICs, DPUs, GPUs)
• Design lossless, RDMA-enabled datacenter networking
• Drive architectural decisions across SR-IOV, vDPA, RDMA/RoCEv2, VXLAN, and firewall placement
• Align infrastructure design with Kubernetes/OpenStack and multi-tenant operational models
• Act as the technical authority across networking, systems, virtualization, and GPU performance domains

Nice to have:

• Be familiar with NVIDIA GPUs, ConnectX NICs, and BlueField DPUs
• Experience with RDMA-enabled, lossless Ethernet fabrics for NVIDIA GPU clusters
• Understanding of GPUDirect RDMA, NCCL scaling, and GPU interconnect topologies
• Ability to align infrastructure architecture with NVIDIA reference designs and support models

Education: Bachelor's or Master’s degree in Computer Science, Computer or Electrical Engineering, Mathematics, or a related field.
