Summary
Do you have a passion for invention and self-challenge? As part of an extraordinary modem team, you'll craft sophisticated powerful embedded firmware that deliver more performance in our products than ever before! We'll work across teams 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 an Embedded Firmware Engineer passionate about real time critical control on this team, you will be at the center of the embedded 5G/4G/multimode cellular firmware effort within a silicon design group responsible for crafting and productizing powerful cellular SoCs. This position requires someone comfortable will all aspects of embedded firm development, that thrives in a multifaceted multi-functional organization, is not afraid to debate ideas openly, and is flexible enough to shift on constantly evolving requirements.
