Strengthen product quality and technical execution by building unit, integration, hardware-assisted, and hardware-in-the-loop tests; maintaining build and continuous-integration workflows; leading design and code reviews; documenting interfaces and decisions; mentoring engineers; and driving root-cause analysis of regressions and field issues. Implement reliable device communication and update capabilities, including peripheral drivers, framed host-device protocols, CRC-protected messaging, Ethernet/TCP services, embedded networking, bootloaders, flash programming, image verification, and persistent configuration.
