Hardware
At Apple, we work every single day to craft products that enrich people’s lives. Do you love working on challenges that no one has solved yet? As a member of our Wireless Silicon Design group, you will have outstanding and exciting opportunity to build our future products that will delight and encourage millions of Apple’s customers every single day! New generations of emerging applications demand performances in specific definitions. Wireless communication technologies are evolving, and the mission is to develop solutions to enable the next generations of applications to introduce innovations into our life, providing outstanding user experiences. Our goals are to come up with architecture, protocols, coordinated systems and algorithms to achieve robust performances, meeting the demands for the next generations of applications over the practical wireless medium conditions, where we expect more congestions from larger number of devices and co-existing wireless technologies. In this technical role, you will be at the center of a silicon design group, responsible for wireless system design for pioneering wireless SoC products. You will be focusing on leading the developments and collaborate closely with different teams to come-up with specification and design details, implementation, conduct pre-silicon validations, post-silicon bring-up, performance and reliability analysis and optimizations, to assure the solutions achieves the requirements and produce satisfying user level experiences. The focus of the work to enable the next generation applications may be on developing sophisticated architectures, PHY/MAC cross-layer and cross-functional protocol and algorithm designs and radio/PHY integrations, enhancing latency, improved medium efficiency, interference and CoEx management in congested environments, extended ranges, reductions of power consumptions, and more.
Description
Core responsibilities include, but are not limited to, the following: Design and simulate state-of-the-art wireless communication system for next generations of applications. Implement system models and investigate innovative architecture, protocols, algorithms in PHY/MAC cross-layer to mitigate the impact congested radio environment and achieve robust performance. Collaborate with product teams and come up with novel architecture, protocols, integrated systems, algorithms to meet the requirements from the emerging applications in a congested radio environment. Perform simulations to prove the efficiency of the crafted architecture, protocols, algorithms, and validate them on emulation systems. Work with firmware designers to realize the software part of these methods with high efficiency software implementation. Work with digital designers to realize the hardware part of these methods with power and area efficient digital implementations. Bring up, test and characterize the crafted algorithms, optimize the performance to achieve the targeted performances with production qualities on real silicon in lab.
