Role overview
As a Staff Network Engineer at vCluster Labs, you aren't just configuring switches; you are building the automation logic that configures them. AI Clouds run on InfiniBand and high-speed Ethernet fabrics that most teams still wire up by hand, one customer at a time. You will build the automation that turns that fabric into repeatable provisioning logic. You start in a small R&D group alongside our CTO and grow into owning this area as it becomes a core part of our platform.
Responsibilities
- Design and build systems that automatically provision and configure NVIDIA switches and InfiniBand fabrics, including integration with NVIDIA UFM
- Build the control loop that keeps switch, VLAN, and VXLAN state consistent with platform intent, detects drift, and reconciles it safely in production
- Build the NAT gateway and L4 load balancing layer that tenant clusters depend on for connectivity, with failover designed in from day one
- Define how the network layer behaves at large scale: BGP route table limits, convergence, failover, and responses to link, switch, or gateway failures under real AI workloads
- Run automation on real AI Cloud environments, identify issues, and translate operational lessons into product behavior for customers
- Help decide what to build versus integrate with partner solutions, write design and requirements documents, and set standards for networking across vCluster products
Requirements
- Built network automation, not just operated networks: shipped software that programmatically configures switches, routers, or load balancers, ideally as part of a product or internal platform other teams relied on
- Hands‑on experience with NVIDIA UFM, NVIDIA Spectrum or Quantum switches, Cumulus Linux, or NVUE, including programming against their APIs
- Strong command of InfiniBand, VLAN, VXLAN and EVPN, and BGP, including how they behave and fail at production scale
- Run networks at real production scale, observed failures, and fixed root causes with automation rather than runbooks
- Write production code in Go or Python, use version control and code review as a matter of course, and treat network config as code
Nice to have
- Experience tuning fabrics for GPU training or inference workloads such as RoCEv2, congestion control, rail‑optimized topologies, or Spectrum‑X
- Background building network automation at a GPU cloud, hyperscaler, or large CDN
- Experience building L4 load balancers or NAT gateways, including with eBPF/XDP or DPDK
- Contributions to networking or Kubernetes projects such as SONiC, FRRouting, Cilium, or MetalLB
Benefits
- Competitive compensation package, including equity
- Premium health, dental, vision, and life insurance for you and eligible dependents
- Flexible working schedule that prioritizes results over clock‑in/out
- Workplace flexibility: work from any location
- Remote‑first culture with distributed team
