Principal Systems Performance Engineer

As a Principal Systems Performance Engineer, you will lead complex performance studies from the initial question through the final recommendation. You will personally lead the hardest investigations while setting technical direction for the team. Your work will guide SSD architecture and product development and help customers get the best performance from Micron products. This is a hands-on senior individual-contributor role., * Lead application performance studies on enterprise servers, GPU-accelerated systems, and data center storage platforms.

• Deploy customer-representative workloads across one or more areas, such as AI training and inference, checkpointing, KV-cache offload, data preparation, databases, virtualization, and software-defined and object storage.
• Develop test plans with clear hypotheses, realistic configurations, appropriate controls, and repeatable methods.
• Instrument systems and trace I/O from the application through the software and storage stack to the SSD. Measure application throughput, completion time, scaling efficiency, tail latency, consistency, and power, then correlate those results with system and device telemetry.
• Isolate bottlenecks across applications, operating systems, drivers, networks, PCIe, NVMe, and storage devices. Recommend software, system, or product changes based on the findings.
• Build automation, test harnesses, and analysis tools that improve test coverage, repeatability, and turnaround time.
• Evaluate new SSD features, system architectures, and competing solutions with real applications and customer use cases.
• Turn test results into engineering reports, technical briefs, reference architectures, and presentations for engineering teams, customers, and executives.
• Work directly with SSD architects, product engineers, customer teams, and ecosystem partners to translate findings into architecture, product-roadmap, software, and customer-deployment decisions.
• Set technical direction for performance work, review methods and results, and mentor engineers across the team., Micron does not charge candidates any recruitment fees or unlawfully collect any other payment from candidates as consideration for their employment with Micron.

AI alert: Candidates are encouraged to use AI tools to enhance their resume and/or application materials.
