Youl'll be designing, deploying, andoperatingthe switch fabrics and interconnects that power large-scale training and inference workloads.

16th September, 2026

About the Role
One of our clients are building out their network backbone that connects and orchestrates thousands of GPUs at scale.
You'llbe joining a team working withcutting-edgeNvidia hardware and high-performance networking technologies that few localorganisationsoperateat this scale.
The role:

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

Experience needed:

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