RF Systems Architect Control Algorithms

At Apple our work is dedicated to creating products that connect and enrich peoples lives. The Cellular RF Systems Engineering team sits at the very core of that mission defining the wireless technologies that enable seamless experiences for hundreds of millions of users worldwide. nnWe are looking for a passionate engineer to design the intelligent control algorithms that orchestrate our RF Front-End hardware. By translating complex 5G and 6G use cases into optimized RF hardware control strategies you will directly balance RF performance power consumption and thermal limits to deliver a world-class wireless experience.

In this role you will be responsible for the optimal interaction between our RF transceivers and RF Front-End modules. Your primary focus will be breaking down advanced cellular capabilities such as SRS antenna switching MIMO and Multi-SIM into clear system requirements and concrete control flows. This is a highly collaborative role where you will partner with diverse engineering teams across the entire cellular stack to bring these cutting-edge concepts into our next-generation cellular products.

Analyze complex cellular radio access use cases and specify the required RF hardware control optimization strategies that maximize RF performance and hardware utilization for demanding scenarios like comprehensive system architecture specifications to guide design implementation and validation end-to-end system performance by collaborating tightly with baseband SoC RF firmware and RF hardware system architectures and algorithms through rigorous simulation and automated requirements analysis.
