Work with a team of component validation, integration, protocol test engineers, firmware developers and system engineers to create firmware verification test cases and end to end physical layer performance Design and develop validation frameworks for the 4G/5G firmware Design, develop, and execute test cases for the 4G/5G firmware and debug and analyze issues found during the testing Create test automation of 4G/5G UEs, test simulators and test gNodeBs. Verify key protocol, signal processing and numerical algorithms with very tight time, latency and energy budgets. Work with Systems/Firmware teams to perform validation of new and existing features. Assist in the development of pre-silicon emulation systems/virtual platforms and use them for pre-silicon firmware design and HW verification. Evaluate and implement leading edge tools for build, formal verification and test.
