Imagine what you could do here. At Apple, new ideas have a way of becoming extraordinary products, services, and customer experiences very quickly. Bring passion and dedication to your job and there's no telling what you could accomplish! Join us to help deliver system design of next generation groundbreaking radio access networks. Do you love working on challenges that no one has solved yet? As a member of our dynamic group, you will have the unique and rewarding opportunity to craft next generation wireless technology that will have deep impact on future Apple products and inspire millions of Apple’s customers every single day. Wireless technologies have become a crucial part of all Apple devices that delight our customers. In our unit, we have the mission to research and develop wireless technology for next generation radio access networks across different layers (PHY, MAC, CP, DP) We are looking for an industry seasoned expert and with a deep understanding of state of the art wireless technology. In this role you will lead a cutting-edge research group responsible for creating next generation disruptive radio access technologies over the next decade and a 3GPP standards team responsible for Physical Layer and RF RAN groups. You will work on defining system level concepts, proposing and researching innovative ideas & algorithms, performing complex system simulations, defining rapid prototyping platforms to help prove your ideas and specifying RAN protocols and for next generation (6G) cellular systems.
