Job summary

VCluster Labs is seeking a Staff Network Engineer to design and automate provisioning of NVIDIA switches and InfiniBand fabrics. You will replace manual, per‑customer setup with repeatable, codified automation and own this area as it scales across our AI cloud platform.

You’ll build the control loops for switch, VLAN, and VXLAN state; implement NAT gateway and L4 load balancing; and define scale and failure behavior for production AI workloads.

Qualifications

• You have built network automation, not just operated networks: you shipped software that configures switches, routers, or load balancers programmatically, ideally as part of a product or internal platform other teams relied on.
• NVIDIA networking experience: hands-on work with NVIDIA UFM, NVIDIA Spectrum or NVUE, including programming against their APIs.
• Deep fabric fundamentals: strong command of InfiniBand, VLAN, VXLAN and EVPN, and BGP, including how they behave and fail at production scale.

Responsibilities

• Fabric automation: design and build systems that automatically provision and configure NVIDIA switches and InfiniBand fabrics.
• Network config management and sync: build control loop to keep switch, VLAN, and VXLAN state consistent with platform intent.
• NAT gateway and L4 load balancing: build gateway and load balancing layer for tenant clusters.
• Scale and failure engineering: define behavior at large scale, including BGP limits, convergence, failover.
• Customer Zero for AI networking: run automation on real AI Cloud environments and derive product improvements.
• Technical direction: help decide what to build vs. integrate and set networking standards across products.
