Debug complex issues across schematics, PCBAs, firmware, actuators, and robot systems using lab instrumentation (DMMs, oscilloscopes, logic analyzers, network analyzers, power analyzers, etc.) and common network protocols (CAN, SPI, I²C, Ethernet, etc.). Perform component, schematic, board, and full system-level bring-up and validation testing; participate in design reviews; manage validation activities across multiple PCBAs in parallel.
