This role combines hands-on performance analysis with validation strategy, project ownership, and customer-facing collaboration.\nThis position is intended for an experienced validation or performance engineer with hands-on experience in server performance testing and analysis who can independently manage assigned validation scope while collaborating closely with experienced team members and cross-functional partners. We also welcome system integration test or validation engineers with substantial performance-related experience who are interested in specializing in performance validation, with opportunities and technical support to deepen their performance analysis capabilities and expand into GPU performance validation.\nKey Responsibilities\nOwn server performance validation activities across compute, memory, storage, network, GPU, and other subsystems.\nPerform performance analysis, regression analysis, issue isolation, bottleneck identification, and root cause investigation across different platforms, configurations, operating systems, and product generations.\nExecute and manage performance validation cycles, ensuring test coverage, execution quality, and milestone delivery.\nProduce technical reports documenting test configurations, methodologies, results, observations, bottlenecks, and recommendations.\nIdentify test tooling, data processing, and automation requirements, and work with the internal automation team to define scope, priorities, and acceptance criteria.\nDesign and review performance validation plans, benchmark methodologies, workload coverage, and acceptance criteria based on product architecture and customer requirements.\nReview customer requirements and platform design documents; define expected performance behavior and validation strategy accordingly.\nPlan and control test schedule and resources where applicable.\nTrack and highlight performance defects, technical risks, validation gaps, and overall status to project teams and management.\nRepresent performance validation in internal design reviews, issue-triage discussions, and customer-facing project meetings.\nQualifications\nBachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, or related technical field.\n8+ years of experience in server system validation, system integration testing, or performance engineering, with hands-on experience in server performance testing and analysis, covering server platforms, storage systems, or AI infrastructure.\nHands-on experience in server performance testing and analysis, with demonstrated technical knowledge in at least one of the following domains:1. Compute and Memory: CPU performance, memory bandwidth, and NUMA behavior (e.g., STREAM, HPL, SPEC CPU)\n2. Storage: Throughput, IOPS, and latency across different storage devices (e.g., fio, IOmeter)\n3. Network: Throughput, latency, and tuning validation across Linux and Windows environments (e.g., NTttcp, iperf2/iperf3)\n\nAbility to independently investigate performance degradation beyond benchmark execution, including regression analysis, issue isolation, bottleneck identification, cross-platform comparison, and optimization recommendations.\nExperience in test planning, benchmark coverage definition, schedule control, and resource coordination across cross-functional teams.\nWorking knowledge of Linux and Windows server environments, including common system resource monitoring tools (e.g., htop, iostat).\nWorking knowledge of shell scripting, batch, or PowerShell for test execution and data handling.\nAbility to quickly learn and adapt to new server technologies and architectures, including next-generation GPU platforms.\nAbility to communicate technical requirements, findings, and risks in English, both written and verbal, in a cross-site working environment.\nPreferred\nExperience with GPU server platforms such as NVIDIA GB200, GB300, or MGX-based systems, including GPU topology, NVLink, RDMA/RoCE, or GPU-to-network performance behavior, and related tools such as NCCL Tests, NVBandwidth, or DCGM.\nExperience validating ARM-based server platforms in addition to x86.\nExperience with performance data analysis, result aggregation, and visualization for regression tracking.\nAbility to independently analyze performance behavior and communicate technical conclusions to customers and stakeholders with strong technical backgrounds, with learning agility to adopt new server technologies.\nAdvanced English proficiency for direct customer engagement.","description_format":"text","description_chars":4695,"description_truncated":false,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[{"language":"English","level":"All
