You will deploy, operate, troubleshoot, and improve these platforms across our global data centre footprint to provide a powerful alternative to traditional hyperscalers.

In this role, you will troubleshoot Linux, networking, hardware, firmware, performance, and stability issues in production, build automation to improve runbooks, dashboards, alerts, and lifecycle workflows, participate in on‑call rotations, lead incident responses, conduct root cause analyses, and collaborate cross‑functionally to ensure reliable workflows at scale.

• Technical experience troubleshooting server, network, GPU, or data‑centre hardware.
• Practical scripting or automation experience with Python, Go, Bash, or similar languages.
• Clear written and verbal communication, documentation skills, and readiness to participate in an on‑call rotation.
• High curiosity to learn specialized GPU interconnect technologies such as NVLink, NVSwitch, and InfiniBand.

Preferred:

• Experience with Ansible or other infrastructure‑as‑code and configuration automation tooling.
• Kubernetes application development or live platform operations experience.
• Familiarity with modern observability systems, including Grafana, Prometheus, PromQL, or similar stack components.
• Experience managing large fleet operations across Linux systems, network devices, GPUs, or infrastructure components.
• Deep understanding of InfiniBand, RDMA, HPC networking, or low‑latency/high‑bandwidth fabrics.
• Experience with BMC, Redfish, IPMI, firmware lifecycle management, or hardware management APIs.
• Exposure to NVLink, NVSwitch, NVIDIA GPU platforms, NVUE, SONiC, or specialized network operating systems.

Benefits

In addition to a competitive salary, we offer a variety of benefits to support your needs, including:

• Family‑level Medical Insurance
• Family‑level Dental Insurance
• Generous Pension Contribution
• Life Assurance at 4x Salary
• Critical Illness Cover
