Cloud Network Engineer II

The High Performance Computing and Artificial Intelligence (HPC and AI) team is focused on building the next-generation distributed artificial intelligence supercomputer. Our goal is to enable breakthroughs in artificial intelligence by delivering unmatched computational power, scalability, and reliability. We design and develop advanced infrastructure that supports high-performance model training at scale, laying the groundwork for innovations that expand the boundaries of what artificial intelligence can achieve.

• Network Design & Implementation: Architect and deploy high-throughput, low-latency physical network topologies (e.g., Clos, FatTree) using technologies such as InfiniBand and Ethernet to support AI model training and HPC workloads.
• Infrastructure Automation: Develop and maintain automation frameworks for provisioning, validating, and monitoring physical network infrastructure at scale, ensuring consistency and reliability across data centres.
• Operational Readiness: Serve as a Designated Responsible Individual (DRI) for physical network systems—monitoring health, responding to incidents, performing root-cause analysis, and driving improvements in availability and observability.
• Tooling & Instrumentation: Build and integrate tooling for telemetry, diagnostics, and performance tuning of physical network components, enabling real-time visibility into link health, congestion, and jitter.
• Cross-Functional Collaboration: Partner with hardware engineering, DataCentre operations, and software-defined networking teams to ensure seamless integration of physical and logical network layers.
• Documentation & Standards: Own the documentation of physical network designs, cabling standards, and deployment procedures. Lead design reviews and ensure alignment with compliance and safety standards.
• Innovation & Research: Stay current with advancements in optical networking, high-speed interconnects, and AI/HPC fabric technologies. Evaluate and integrate emerging solutions to improve scalability, efficiency, and performance.
