Wireless PHY Systems Engineer

Join Apple's Wireless SoC team - one of the most innovative and high-impact groups in the industry - where we define next-generation modem architectures, develop cutting-edge physical-layer algorithms, and invent embedded DSP solutions that power products like AirPods, Apple Watch and iPhone.\\n\\nAs a Wireless PHY Systems Engineer, you will play a central role in building end-to-end simulation frameworks for sophisticated wireless systems. Your work will span the full signal chain from propagation channel modeling and RF/antenna behavior to PHY & MAC protocols and signal processing algorithms. Application areas include Bluetooth-based wireless audio and ultra-wideband (UWB) sensing - technologies that define the user experiences Apple is known for.\\n\\nThis is a rare opportunity to work at the intersection of wireless systems research, algorithm development, and silicon engineering, with direct impact on products used by hundreds of millions of people worldwide.

In this role, you will be responsible for the modeling, simulation, and performance analysis of complex wireless systems across multiple protocol layers and signal processing domains. You will work closely with PHY systems and algorithm engineers, analog and digital designers, and firmware/software engineers to invent, simulate, implement, verify, and test physical-layer features for new SoC designs.\n\nYou will leverage AI-assisted simulation and data analysis techniques to accelerate development cycles, uncover system-level insights, and improve the accuracy and scalability of end-to-end models. Your contributions will directly shape the architecture and performance of next-generation wireless chips.
