Job Description Location: Hong Kong — Hybrid (factory floor, test lab and manufacturing sites; this is not a remote or desk-based role) Start date: ASAP Languages: Fluent English and fluent Mandarin are both mandatory Industry: HPC / GPU Server Manufacturing / Sovereign Cloud Infrastructure Pragmatike is recruiting on behalf of a European deep-tech company building a sovereign, energy-efficient alternative to traditional cloud providers. Unlike most cloud players, our client designs and manufactures its own HPC infrastructure end to end — chassis, boards and containerized units — and deploys it as the hardware layer of a vertically integrated AI cloud. The company is growing fast and is expanding its manufacturing and testing capability in Hong Kong. Professional Background: We're looking for a Server Engineer with hands-on GPU/HPC hardware experience who has tested and validated servers, not just operated them. You should be comfortable moving between the factory floor and the test lab, with a strong Linux background and real familiarity with firmware and GPU software stacks (CUDA, NCCL). You take ownership of quality: if a server ships, it is because you signed off on it. Startup or hyper-growth experience is a strong plus. Autonomy, rigor and problem-solving are essential. Your Responsibilities: * 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. What You Bring: * 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. Why Join Us: Our client is one of the very few cloud companies that builds its own hardware from the board up. Their mission is to deliver a sovereign, energy-efficient, high-performance alternative to traditional cloud providers, and the servers you test and validate are the physical foundation of that platform. Expect real ownership from day one, a fast-paced environment that values autonomy and problem-solving, and the chance to build something that doesn't exist yet.
