Be a part of the engineering team responsible for designing, developing, and integrating embedded software for radio front-end, transceiver, and baseband control on the worlds most advanced wireless modems. Innovate, design, and implement C/C++ embedded drivers for cutting edge RF and modem hardware technology for WWAN standards including: sub6/mmW 5G, LTE, WCDMA/HSPA, CDMA2000, TD-SCDMA and GSM/EDGE.
Participate in the product development lifecycle from inception and design to bring-up, optimization, verification and commercialization. Provide a software abstraction layer to seamlessly support a variety of radio hardware configurations on a common protocol stack. Interface with cross-functional teams within the overall modem organization: ASIC design, modem/RF systems, systems test, hardware, protocol, FW, common software, power management. Design and implement test mode interfaces to enable hardware characterization and tuning procedures to optimize RF performance. Design and implement the software control for cutting edge power optimization systems to enable efficient transmit operation while maintaining RF spectrum emissions requirements. Optimize device control transactions to meet strict timing requirements for inter-RAT operation.
