Hardware-facing development or lab debugging using interfaces such as PCIe, I2C, SPI, UART, ADCs, or DACs; JTAG debugging and schematic reading
Embedded Linux build and development tools such as Yocto, cross-compilation, Python, Go, or shell scripting.

Skills

Linux networking or network management software, including experience with one or more of SONiC, OpenConfig, YANG, gNMI, gNOI, SNMP, or NETCONF.
Distributed or service-based software using technologies such as Redis, Docker, gRPC, or Protocol Buffers.
