Cloud Storage Test Engineer
Posted
The Storage Test Engineer will serve as a hands-on technical contributor within Western Digital's System Integration & Test (SIT) lab, focused on deploying, operating, and validating clustered storage environments that accurately reflect real-world cloud and datacenter infrastructure. Working closely with the Clustered Storage Test team and HDD System Test groups, this engineer will configure scale-out storage clusters, design and execute various workloads and SLA validation tests, measure and analyze system and drive performance, and monitor drive health telemetry. This role is ideal for an engineer with 26 years of experience in storage systems or infrastructure who is ready to go deep on distributed storage behavior, performance characterization, and large-scale fleet operations.
ESSENTIAL DUTIES AND RESPONSIBILITIES
- Deploy and operate scale-out storage environments including multi-node object storage clusters, erasure-coded pools, and rack-level storage deployments configured to emulate real customer datacenter architectures at lab scale.
- Measure and analyze storage system and drive performance characterizing throughput, IOPS, and latency distributions across workload profiles including AI/ML data access patterns, backup and restore traffic, cloud object storage, and web-serving workloads and producing clear performance reports with root-cause observations.
- Identify and investigate performance anomaliesby correlating cluster-level metrics with drive-level telemetry, distinguishing between platform bottlenecks, configuration issues, and drive-level contributors to throughput or latency degradation.
- Analyze technical customer workload studiesand translate key variables into realistic test scenarios and validation methodologies.
- Instrument and monitor drive health telemetry collecting and trending SMART attributes, Error Logs, I/O error rates, and temperature data to identify early failure indicators and correlate drive health signals with observed cluster performance during long-run experiments.
- Contribute to fleet management processesfor the lab's HDD inventory, supporting tracking of drive state, physical location, test assignment, and lifecycle status across large populations of test drives.
- Assist with datacenter infrastructure managementtasks including rack-level storage deployments, drive swap procedures, firmware staging, and hardware validation during active cluster tests.
- Document test configurations, performance results, and failure analysesin detailed technical write-ups that allow peer engineers to reproduce experiments, compare results across configurations, and build on prior findings.
- Collaborate with senior engineersto identify gaps between existing test methodologies and modern cloud storage deployment patterns, then help design and implement updated test scenarios, workload mixes, or cluster configurations that close those gaps.
- Evaluate storage benchmarking tools and workload generators, assessing their suitability for emulating specific customer traffic profiles and recommending configurations that produce the most representative and actionable results.
