Define hardware-software interfaces and lead board bring-up/debug strategy with embedded software and firmware engineers, using lab instrumentation (oscilloscopes, logic analyzers, protocol analyzers, DC power supplies) to validate designs and troubleshoot issues at the component, board, module, and system level. Lead high-speed digital PCB design, including multi-Gbps interfaces (e.g., PCIe, SpaceWire, Ethernet), backplane bus architectures, memory and storage interfaces, clock generation and distribution, and data acquisition/control circuits.
