📋 Description

• Design and develop systems that automatically provision and configure NVIDIA switches and InfiniBand fabrics, incorporating NVIDIA UFM integration.

• Create network configuration control loops that maintain consistent switch, VLAN, and VXLAN states, identify drift, and safely reconcile it in a production environment.

• Construct NAT gateway and L4 load-balancing layers with failover capabilities.

• Establish network-layer behavior at scale, addressing BGP route-table limits, convergence, failover, and infrastructure failures.

• Execute automation in real AI Cloud environments and translate operational insights into product functionality.

• Determine whether to build solutions or integrate with partner offerings.

• Draft design and requirements documentation.

• Establish networking standards across vCluster products.

• Collaborate with the CTO and a small R&D team, gradually taking ownership of the networking domain.

⛳️ Requirements

• Proven experience in developing network automation that programmatically configures switches, routers, or load balancers.

• Practical experience with NVIDIA UFM, NVIDIA Spectrum or Quantum switches, Cumulus Linux, or NVUE, including API programming.

• Strong understanding of InfiniBand, VLAN, VXLAN, EVPN, and BGP protocols.

• Experience managing networks at a real production scale and resolving root causes through automation.

• Production-level coding experience in Go or Python.

• Familiarity with version control systems and code review processes.

• Experience optimizing fabrics for GPU training or inference workloads, including RoCEv2, congestion control, rail-optimized topologies, or Spectrum-X.

• Background in a GPU cloud, hyperscaler, or large CDN.

• Experience in building L4 load balancers or NAT gateways, including with eBPF/XDP or DPDK.

• Contributions to networking or Kubernetes open-source projects such as SONiC, FRRouting, Cilium, or MetalLB.

• Authorization to work in the US for vCluster Labs.
