Your hands-on debug capability, structured root-cause mindset, and ability to connect board-level signals with system-level behavior will be essential to driving customer-return investigations from symptom confirmation through technical root cause and corrective action closure. Confirm, reproduce, and isolate complex power failures such as no power, intermittent boot, unexpected shutdown, brown-out, rail droop, over-current protection, under-voltage protection, sequencing faults, hot-plug events, and margin-related failures.
