Full Job Description
About us Graphcore is one of the world’s leading innovators in Artificial Intelligence compute. It is developing hardware, software and systems infrastructure that will unlock the next generation of AI breakthroughs and power the widespread adoption of AI solutions across every industry. As part of the SoftBank Group, Graphcore is a member of an elite family of companies responsible for some of the world’s most transformative technologies. Graphcore’s teams are drawn from diverse backgrounds and bring a broad range of skills and perspectives. Job Summary We are seeking a Staff System Validation Engineer to design and implement validation tests for Arm-based data center SoCs using a combination of open-source benchmarking tools and custom micro-benchmarks. Define test cases, tune workload parameters, and use Python to automate and analyze validation across processing units, system memory, communication links, and PCI Express components. The Team The Systems Validation team validates Graphcore’s AI compute platforms across hardware, firmware, and software domains. Responsibilities and Duties Translate hardware features into structured, parameterized test cases, including: Objectives, workload models, parameters, metrics, and pass/fail criteria. Use and tune open-source tools such as: Stress-ng, fio, iperf, sysbench, Imbench Define workload parameters: Concurrency (threads/cores), memory footprint, access patterns Queue depth, block size, CPU/NUMA affinity. Design and execute validation scenarios: Functional, performance, stress, and corner-case testing. Validate across domains: CPU scaling and cache behavior Memory (DDR/HBM) bandwidth, latency, and NUMA effects Interconnect contention under multi-core load PCIe/I-O throughput, latency, and multi-device scenarios Develop custom micro-benchmarks (C/C++) when existing tools are insufficient Use Python to: Automate test execution and orchestration Implement parameter sweeps and test matrices Parse, analyze, and visualize
