Cellular RF Systems Architect - Control Algorithms (m/f/d)

At Apple, our work is dedicated to creating products that connect and enrich people's 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.
We 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.
<h3>Minimum Qualifications</h3>BS in Electrical Engineering, Physics, or a related field with 3+ years of industry experience in RF systems or transceiver architectures.
Deep understanding of 5G NR and LTE-Advanced physical layer procedures, particularly involving MIMO, SRS, and carrier aggregation.
Strong working knowledge of RF Front-End architectures and the system-level impact of components like PAs, LNAs, filters, and switches.
Proven track record of developing control algorithms, state machines, or system-level models for complex hardware.
Proficiency in Python, MATLAB, or C/C++ for data analysis, system modeling, and algorithm development.
Ability to critically analyze complex trade-offs, such as routing flexibility versus insertion loss, or throughput versus battery life.
Strong communication skills with a proven ability to work across diverse, cross-functional teams to solve highly complex, multi-disciplinary problems.
<h3>Preferred Qualifications</h3>MS or PhD in Electrical Engineering with a focus on advanced cellular communication topics.
5+ years of experience in RF systems engineering or 10+ years in communications circuit design.
Hands-on experience with RF filter technologies, power amplifier characterization, and Front-End module integration.
Expertise in designing and simulating analog and digital signal processing paths.
Experience applying Machine Learning or AI techniques to solve system-level optimization problems.
History of successfully balancing cutting-edge hardware innovation with the practical constraints of high-volume manufacturing.
