Lenovo is a global leader in AI infrastructure, high-performance computing, and data centre technologies, helping customers build and scale next-generation accelerated computing environments. As part of the Lenovo Infrastructure Deployment Services (LIDS) team, you will support the validation, benchmarking, and optimisation of large-scale HPC and AI solutions for some of Lenovo's most strategic global customers. In this role, you will execute performance testing, analyse benchmark results, and provide optimisation recommendations across cutting-edge HPC and AI environments, working closely with customers, architects, consultants, and engineering teams. You will be part of a global team supporting EMEA and worldwide projects and will report directly to the Global HPC Delivery Leader. What You Will Do: Validate, benchmark, and optimize large-scale HPC and AI platforms, ensuring systems meet performance targets, customer expectations, and acceptance criteria. Design and execute benchmarking and performance test plans across compute, storage, networking, GPUs, and AI workloads, then analyze and present results. Profile applications, identify performance bottlenecks, and provide practical optimization recommendations for HPC, AI, and GPU-accelerated environments. Work with industry-standard HPC benchmarks, AI training and inference workloads, MPI-based applications, storage testing tools, and large-scale cluster validation processes. Partner closely with customers, solution architects, technical consultants, delivery teams, and technology partners to support successful solution deployment and operational readiness. Contribute to the development of benchmarking methodologies, best practices, technical documentation, training materials, and knowledge-sharing initiatives that strengthen Lenovo’s global HPC and AI capabilities. What You Will Bring: Strong experience with High Performance Computing (HPC) environments, including cluster architectures, Linux administration, job scheduling, and distributed computing. Proven ability to execute, analyse, and optimise HPC benchmarks and performance validation tests across compute, storage, and networking infrastructure. Solid knowledge of parallel computing technologies, including MPI, OpenMP, CUDA, NCCL, and GPU-accelerated applications. Experience benchmarking and tuning scientific, engineering, AI, and data analytics workloads on large-scale HPC platforms. Strong understanding of NVIDIA GPU technologies and architectures, including H100, H200, B200, and GB200/GB300. Hands-on experience with high-performance networking technologies such as InfiniBand and RoCEv2. Expertise with industry-standard benchmark suites including HPL, HPL-MxP, HPCG, IO500, MLPerf, STREAM, FIO, IOR, and NCCL tests. Knowledge of Top500, Green500, customer acceptance testing methodologies, and HPC performance benchmarking best practices. Experience working with HPC storage solutions such as Lustre, GPFS (IBM Storage Scale), BeeGFS, VAST, WEKA, or similar parallel file systems. Strong Linux skills across RHEL, Rocky Linux, and Ubuntu, combined with shell scripting for automation, benchmark execution, and performance analysis. Ability to identify performance bottlenecks, deliver optimisation recommendations, and create customer-facing benchmark reports, technical documentation, and performance studies. Excellent communication and problem-solving skills, with the ability to work directly with customers, architects, and engineering teams; experience with AI infrastructure benchmarking, LLMs, PyTorch, TensorFlow, Kubernetes, OpenShift, cloud HPC (Azure/AWS/GCP), Python automation, GPU profiling tools, and enterprise AI acceptance testing is highly desirable.
