Role Number:200514775
Do you have a passion for invention and self-challenge? As part of an extraordinary modem team, you’ll craft sophisticated groundbreaking embedded firmware that delivers more performance in our products than ever before! We’ll work across subject areas to transform improved hardware elements into a single, coordinated design. Join us, and you’ll help us innovate new wireless systems technologies that continually outperform the previous iterations. By collaborating with other product development groups across Apple, you’ll push the industry boundaries of what wireless systems can do and improve the product experience for our customers across the world! As a 5G/4G Physical Layer Firmware Verification and Integration Engineer, you will be at the center of the embedded 5G/4G/multimode cellular physical layer firmware effort within a silicon design group responsible for crafting and productizing powerful cellular SoCs. This position requires someone comfortable with all aspects of embedded firmware verification and integration, who thrives in a wide-ranging multi-functional organization, is not afraid to debate ideas openly, and is flexible enough to shift on constantly evolving requirements.


Work with a team of component validation, integration, protocol test engineers, firmware developers, and system engineers to build firmware verification test cases and end-to-end physical layer performance. Design and develop validation frameworks for the 4G/5G firmware. Design and develop test cases for the 4G/5G firmware and debug and analyze issues found during the testing Build 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 powerful tools for build, formal verification, and test
