Summary

At Apple we craft products that enrich people’s lives. Do you love working on challenges that no one has solved yet? Do you like changing the game? We have an opportunity for a forward-thinking and hardworking Wireless System Engineer. As a member of our multifaceted group, you will have the rare and extraordinary opportunity to craft upcoming products that will delight and encourage millions of Apple’s customers. In this technical role, you will be at the center of a silicon design group responsible for system design of pioneering wireless SoC’s for very high data rate applications. You will focus on finding innovative solutions to challenging PHY/MAC Cross Layer problems with the goal of achieving robust system performance in dynamically changing and congested radio environments. This will include proposing, simulating, supporting SW/HW implementation, bringing up in the lab, and optimizing advanced algorithms addressing areas such as rate adaptation, interference management and coexistence. You will work closely with SW engineers, HW digital designers, architects, and Product teams to achieve these goals. Good interpersonal skills will be essential to understand domain requirements and constraints - and converge to a final solution that achieves performance, cost, power, and other requirements.

Minimum Qualifications
