AI Infrastructure Hardware Engineer

The role

This person will own quality control across manufacturing sites and run the hardware test lab. They will validate GPU servers and diagnose hardware, firmware, and driver-level issues.

What you will do

• Own quality control across the client's manufacturing sites, on the factory floor.
• Run the hardware test lab: board and system bring-up, validation and stress testing of new server builds.
• Oversee the assembly and end-to-end testing of GPU servers before they are deployed into the client's sovereign cloud.
• Define and maintain test procedures, acceptance criteria and QC checkpoints for chassis, boards and full systems.
• Diagnose hardware, firmware and driver-level issues (BIOS/BMC, GPU firmware, PCIe, thermals, power) and drive root-cause analysis with the design and manufacturing teams.
• Validate GPU compute and interconnect performance under Linux using CUDA, NCCL and related benchmarking tools.
• Document failures, yields and test results, and feed findings back into hardware design and production processes.
• Coordinate day to day with manufacturing partners and local suppliers in both English and Mandarin.

Required qualifications

• Proven hands-on experience testing and validating GPU/HPC servers (bring-up, burn-in, validation), not only using them.
• Strong Linux skills at the system and hardware level.
• Firmware knowledge: BIOS/UEFI, BMC/IPMI, GPU and NIC firmware, flashing and troubleshooting.
• Working knowledge of the NVIDIA GPU stack: drivers, CUDA, NCCL, and how to benchmark and diagnose multi-GPU systems.
• Solid understanding of server hardware: motherboards, PCIe topology, power, cooling, storage and networking components.
• Experience with QC or manufacturing test processes in a hardware production environment.
• Fluent English and fluent Mandarin (both non-negotiable).
• Willingness to work on-site in Hong Kong, on the factory floor and in the lab.

Nice to have

• Experience with containerized or micro-datacenter deployments (power, thermal and environmental constraints).
• Familiarity with high-speed interconnects (InfiniBand, RoCE, NVLink) and their validation.
• Scripting skills (Bash/Python) to automate test sequences and reporting.
• Exposure to hardware supply chains or contract manufacturers in Hong Kong / Southern China.
• Cantonese.
• Startup or hyper-growth experience is a strong plus.
