As a Wireless Embedded Physical Layer Data Path Signal Processing Firmware Engineer at the senior level within a silicon design group, you will play a pivotal role in developing embedded 4G/5G multimode cellular firmware for powerful SoCs. Your daily tasks include implementing physical layer algorithms on digital/vector signal processors with strict constraints and interfacing with specialized ASIC hardware to execute 3GPP channels and procedures such as PDCCH, PDSCH, PBCH, PUCCH, PUSCH, PRACH UL/DL HARQ. You will collaborate closely with systems engineers to optimize firmware architecture for efficiency, develop fixed-point firmware, and validate bit-exactness. Additionally, you will contribute to pre-silicon emulation systems and innovative verification tools, requiring expertise in digital signal processing, linear algebra, and scripting languages like Python. Knowledge of 3GPP standards and machine learning concepts is highly valued.
