n
- Design, build, andoperatehigh-performance network fabrics supporting large-scale GPU clusters
n
- Deploy and tune switch fabrics for low-latency, high-throughput AI/ML workloads
n
- Work closely with infrastructure and platform teams tooptimisenetwork performance for distributed training and inference
n
- Troubleshoot and resolve complex network issues across HPC and GPU-dense environments
n
- Plan capacity and topology for ongoing GPU infrastructure expansion
n
- Partner with vendors (including Nvidia) on hardware qualification, firmware, and fabric design

n
- Hands-on experience withhigh performancecomputing (HPC) networking environments
n
- Strong understanding of GPU infrastructure and the networking demands of AI/ML workloads
n
- Experience with switch fabric design, deployment, and operations at scale
n
- Familiarity with Nvidia networking technologies (e.g.InfiniBand, Spectrum-X,NVLink/NVSwitchecosystems)
n
- We'llalso consider candidates without direct HPC/AI experience if they bring:
n
- Large-scale network engineering experience from ahyperscaleror major cloud provider (e.g.AWS, Azure, Google Cloud) or equivalent big-tech setting
n
- Proven experience designing oroperatinglarge, complex switch fabrics in production — this background is scarce in the Australian market and highly valued
n
- A track recordof operating at scale (thousands of nodes/ports) rather than traditional enterprise networking
