Would you like to join Apple’s growing wireless silicon development team? Our wireless SOC organization is responsible for all aspects of wireless silicon development, taking care of challenges from the complex usages, more demanding performances and reliabilities to enable emerging wireless applications and products. Our goal is to come up with novel architectures and protocols, integrated systems and algorithms with employing the advanced technologies to introduce our innovative products, providing evolutions to our lives.

In this technical role, you will be at the center of our silicon design and bring-up group, responsible for the wireless system design of our innovative wireless SoC products. You will take significant part in developing the next generations of wireless communication systems for enhanced performances and reliability, creating novel algorithms, protocols and architectures. You will participate in cross-functional task forces, comprising of RF/analog, HW, SW, platform designers and architects. This role contains wide responsibly on implementation, verification, validation and bring up our SoC products to the production quality, providing them to our customers

Description

In this role, you will be required to demonstrate strong analytical skills, innovative thinking, and fundamental knowledge to design the creative algorithms, innovative architectures and protocols, to resolve the challenges and issues and develop the best-in-class solutions in terms of performance, power, and area. You will also collaborate closely with HW digital designers and architects, RF/analog designers, and SW teams to define and specify the wireless systems.
