About The Position

This individual possesses the solid engineering fundamentals and understanding with some supervision in the application of Modem knowledge to assist in the design, implementation, verification, validation, and commercialization of Wireless WAN (or cellular) modem air interface RAN technologies software. Assists in the transceiver, HW control, and wireless Radio Access Stratum software implementation of a multi-RAT (Radio Access Technology) from industry specifications (most notably 3GPP with LTE and 5GNR). Applies knowledge of RF and/or WWAN L1/L2/L3 specifications to assist in the implementation of the shared resources of a multi-mode modem. Assists in the development of models and simulations to design a well-defined component. Collaborates with team members to develop a 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). Develops test cases to test/verify design for a well-defined component to validate modem against specifications. Writes technical documentation and feature descriptions for Modem Tech SW projects. Engage in the product development lifecycle from inception and design to bring-up, optimization, verification, and commercialization. Construct a software abstraction layer to seamlessly support a variety of radio hardware configurations on a common protocol stack. Design and implement test mode interfaces to enable hardware characterization and tuning procedures to optimize RF receive and transmit performance. Optimize device control transactions to meet strict timing requirements for inter-RAT, multi SIM, and concurrent radio operations. Collaborate with multi-disciplinary teams within the overall modem organization: ASIC design, modem/RF systems, systems test, hardware, protocol, firmware, common software, power management. Develop software framework to manage wide-band transceiver resources such as PLLs,hardware blocks, and clock controllers. Collaborate with multi-disciplinary teams to triage and debug power usage and optimize timelines. Participates at design reviews and project meetings.
