Strong experience debugging server PDBs, bridge boards, power distribution paths, VRs, hot-swap circuits, connectors, cables, GPU/accelerator platforms, rack-scale systems, or comparable compute hardware through bring-up, validation, factory, or customer FA phases. Own end-to-end hardware root cause analysis for server PCBAs, with primary depth in power delivery, PDBs, bridge boards, sequencing, connectors, and board-level electrical interfaces while maintaining capability across motherboards and high-speed IO paths.
