“Cloud Storage Test Engineer at Western Digital. Skills: Cloud Storage, Test Engineering, Distributed Storage, Performance Analysis, Scripting. Deploying, operating, and validating clustered storage environments. Configuring scale-out storage clusters”
What You'll Achieve.
Accurately reflect real-world cloud and datacenter infrastructure; Produce clear performance reports with root-cause observations; Identify early failure indicators and correlate drive health signals with observed cluster performance during long-run experiments; Close gaps between existing test methodologies and modern cloud storage deployment patterns; Produce the most representative and actionable results from benchmarking tools and workload generators.
Industry & Context.
Problem solvers; Identify and investigate performance anomalies by correlating cluster-level metrics with drive-level telemetry, distinguishing between platform bottlenecks, configuration issues, and drive-level contributors to throughput or latency degradation.
Working in a physical lab environment with servers, HBAs, JBODs, and storage controllers.
What They're Looking For.
Must Have
Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, or a related technical field., 2–6 years of hands-on experience in storage systems, distributed infrastructure, or storage test and validation engineering., Familiarity with scale-out storage architectures and an understanding of how distributed object or block storage clusters are structured, scaled, and managed in production environments., Exposure to S3-compatible object storage (MinIO, AWS S3, or equivalent), including operational concepts such as bucket management, erasure coding, and performance benchmarking., Linux command-line comfort working in a physical lab environment with servers, HBAs, JBODs, and storage controllers., Solid scripting ability (Python, Bash, or similar) sufficient for automating test execution, parsing results, and building lightweight data-processing utilities.
Nice to Have
Familiarity with drive health monitoring and telemetry — including SMART attribute collection, error log analysis, and correlating drive-level signals with system-level performance observations., Exposure to rack-level storage deployment practices: server racking, HBA and storage controller configuration, JBOD/JBOF cabling and validation., Familiarity of erasure coding and how EC parity levels affect storage efficiency, durability, and rebuild performance under drive failure conditions., Experience with fleet management concepts or tooling for tracking and auditing large inventories of physical storage devices across a lab or datacenter environment., Familiarity with SLA testing methodologies — defining availability and durability targets, instrumenting measurement, and validating cluster behavior against those targets under both normal and degraded conditions., Experience with storage benchmarking tools such as Warp, fio, vdbench, or similar workload generators., Experience with automation tools like Docker, Ansible, Grafana, etc., Knowledge of distributed storage platforms such as Ceph, HDFS, or similar open-source cluster software., Familiarity with datacenter infrastructure management practices including asset lifecycle tracking, capacity planning, and hardware refresh operations., Experience building automated test reports or data pipelines that collect, process, and present performance and health metrics from distributed storage systems — including scheduled report generation, results dashboards, or trend-tracking tooling that surfaces patterns across long-run test campaigns.
