As a 5G/4G Physical Layer Firmware Verification and Integration Engineer, you will collaborate with a diverse team to construct firmware verification test cases and assess the end-to-end physical layer performance. Your responsibilities will encompass the design and development of validation frameworks, the creation and execution of test cases, and the debugging and analysis of issues that emerge during testing. You will be involved in automating tests for 4G/5G UEs, simulators, and gNodeBs, as well as validating crucial protocol, signal processing, and numerical algorithms within strict constraints. Furthermore, you'll contribute to the development of pre-silicon emulation systems and leverage them for firmware design and hardware verification. You'll also evaluate and integrate potent tools for build, formal verification, and testing. This role requires a strong understanding of 4G/5G technologies and a knack for problem-solving.
