Wireless Systems Engineer

Apple is seeking a Wireless Systems Engineer for its Wireless Silicon Design group. The role involves designing wireless communication systems for high data rate applications and creating algorithms and architectures for wireless SoC products. Responsibilities include implementing system models, investigating algorithms for performance enhancements, and validating designs for RTL development. The engineer will also model RF/circuit impairments, define physical layer hardware control procedures for optimal modem performance in congested radio environments, and design algorithms for impairment mitigation using techniques like calibration and pre-distortion. Collaboration with digital and firmware designers for efficient implementations, including hardware acceleration, is crucial. The role also involves bringing up, testing, characterizing, and optimizing real silicon in the lab.
