General Summary: This individual leads, plans, synthesizes ambiguous or conflicting requirements and performs the complex responsibility of leveraging advanced Modem knowledge to design, implement, verify, validate, and commercialize Wireless WAN (or cellular) modem air interface RAN technologies software by working on Modem access stratum and RF SW design, optimizations & algorithms, and with the RFFE team to define the modem IP architecture, RFFE design, HW APIs, core systems algorithms, and HW/SW/co-processor architecture. Collaborates with cross-functional teams to develop a cost effective, high quality, and high capability modem IP that meets industry and customer requirements with high performance (e.g., throughput, latency, power consumption) and acceptable cost (e.g., silicon area, calibration complexity, code size).
