Job description

We are looking for a Senior Data Center Infrastructure & Systems Engineer to lead the technical deployment, network integration, and diagnostic testing of high-density GPU AI cluster infrastructure. The role covers hardware provisioning, network fabric configuration, and rigorous performance validation, transitioning into ongoing monitoring, troubleshooting, and maintenance of the cluster fleet.

Key Responsibilities

• Configure Out-of-Band (OOB) management networks and execute bare-metal OS provisioning, kernel tuning, and CUDA/driver installations across server nodes.
• Deploy and validate high-speed network fabrics (InfiniBand, RoCEv2 Ethernet), including switch configuration, BGP routing, and VXLAN overlays.
• Perform multi-tier hardware validation, including GPU diagnostics, memory bandwidth benchmarks, power stress tests, and multi-node performance benchmarking.
• Conduct burn-in testing, monitor thermal thresholds, and support functional performance acceptance sign-off.
• Execute SLA-driven work orders including hardware troubleshooting, component swaps, and rack-level maintenance.
• Monitor cluster health telemetry (power, temperature, ECC errors, network performance) to proactively identify hardware issues.
• Respond to infrastructure incidents, isolate faulty hardware, and support non-disruptive maintenance and firmware updates.
• Maintain accurate asset inventory records and comply with physical security and data confidentiality policies.

Qualifications & Experience

• Bachelor's Degree in Computer Engineering, Computer Science, Network Engineering, Systems Administration, or equivalent practical experience.
• 3-5+ years of hands-on experience in high-performance computing (HPC), hyperscale data centers, or AI cluster infrastructure.
• Proven experience with high-density GPU server hardware and liquid-cooled rack systems.
• Strong Linux systems administration skills (Ubuntu/RHEL), PXE provisioning, and scripting (Bash/Python).
• Expertise in high-speed network fabrics: InfiniBand, RoCEv2, BGP, VXLAN, IPAM.
• Experience with GPU diagnostic tools (NVIDIA DCGM, nvidia-smi, Fabric Manager) and IPMI/Redfish APIs.
• Familiarity with ticketing systems and asset tracking workflows.
• Strong diagnostic and troubleshooting skills for complex hardware/network issues.
• Strict adherence to safety and security protocols.
• Ability to adapt between fast-paced deployment work and structured, SLA-driven operations.

Work Location

You will be based in Johor Bahru, within the Iskandar Puteri area.
