Cellular 5G /4G Physical Layer Firmware Engineer

Role Overview: As a Cellular 5G/4G Physical Layer Firmware Engineer on this team, you will be responsible for implementing key 3GPP protocols and control/data path processing algorithms with very tight time, latency, and energy budgets by interfacing with specialized cellular ASIC hardware. You will work on various processing tasks such as 3GPP channels and procedures including PDCCH, PDSCH, PBCH, PUCCH, PUSCH, PRACH, UL/DL HARQ, and Tracking loops. Additionally, you will collaborate with systems engineers to refine signal processing algorithms for efficient firmware/hardware execution and work with silicon designers to define HW interfaces, processors, bus, DMA, accelerator, and memory subsystems. Your role will involve specifying, designing, and implementing the firmware architecture of an innovative mobile wireless communications system.
