PHY firmware architecture and design, including calibrations, realtime processing flows, collaborate with RF hardware, microcode, and MAC layer. Develop highly efficient designs delivering outstanding performance, minimizing power and memory footprints while meeting hard-realtime latency requirements. Debug realtime systems with limited visibility, working hands-on with development boards and lab equipment. Collaborate with Radio, MAC, and Systems engineering teams to architect, define and implement innovative algorithms, calibrations, and protocols. Support pre-silicon validation efforts, including simulation, emulation, and FPGA prototyping. Develop SoC test and calibration capabilities for chip, module, and product factories. Support post-silicon bringup, validation, performance characterization, system integration and debug.
