• Debug and validate individual server components at the L6 level, including CPUs, DIMMs, NICs, and other subsystems prior to full server assembly.

• Execute L10 level system testing and integration, identifying failures involving power delivery, firmware mismatches, network communication issues, and interconnect instability across fully assembled racks.

• Apply structured troubleshooting techniques to diagnose complex cross-component failures involving switches, PDUs, interconnects, cabling, and/or liquid cooling systems.

• Perform L12 level burn-in testing and final system validation to ensure end-to-end compute, networking, and storage performance prior to customer shipment.

• Collaborate with Quality, Process, and Manufacturing Engineering teams to complete in-depth hardware failure analysis across component, subsystem, and system levels, escalating systemic issues and driving long-term solutions.

Hardware and Firmware Integration : BIOS, POST, PCIe, BMC (~15%)

• Configure and validate BIOS settings to support debug workflows, hardware integration, and test case execution across complex server builds.
