• Coordinate smart hands, OEMs, facilities contractors and network carriers, ensuring work is completed safely and within agreed SLAs.
• Manage vendor support cases and RMAs with partners such as NVIDIA and HPE.
• Maintain accurate asset records, runbooks, known-error documentation and operational processes.
• Produce NOC reporting covering incidents, response and resolution times, backlog, GPU availability and supplier performance.
• Drive continuous improvement by identifying recurring faults, strengthening processes and improving how the team operates.

Required Skills & Experience:

• 5+ years’ experience in NOC, infrastructure or data-centre operations, with team leadership or mentoring experience.
• Strong hands-on Linux and bare-metal server skills, including BMC/IPMI/Redfish, firmware, provisioning and hardware troubleshooting.
• Good networking knowledge across Layer 2/3, routing, switching, optics and cabling.
• Experience leading incidents, working to SLAs and using ITIL-based incident, problem and change processes.
• Experience with monitoring and ITSM tools such as Prometheus, Grafana, PagerDuty, HaloPSA or ServiceNow.
• Experience managing suppliers and smart-hands partners, with a calm, organised approach to working in a 24x7 environment.

Desirable Skills & Experience:

• Experience with NVIDIA GPU infrastructure, including HGX, DCGM, nvidia-smi, NVLink/NVSwitch and GPU diagnostics.
• Knowledge of InfiniBand/RoCE, Kubernetes or Slurm, and infrastructure automation such as Ansible or Terraform.
