The Cellular group is looking for an extraordinary Systems and Algorithms engineer with extensive experience in signal processing, communication systems, and feature integrations to develop and drive pioneering technologies for Apple’s products. As part of the team, you will work on the recent cellular technologies, LTE, 5G, and 6G, to develop and integrate solutions on the cellular Modem, focusing on defining and integrating new solutions. You will have the chance to be part of an exciting development process that brings new solutions to life in groundbreaking areas of cellular chip development, which is a key part of Apple’s products. Imagine what you could do here. At Apple, new insights have a way of becoming extraordinary products, services, and customer experiences very quickly. Bring passion and dedication to your job, and the sky is the limit. We are the home for dynamic, inquisitive, and inspiring people and innovative technologies.

Leading role in developing and integrating features in the systems and algorithms for Cellular modems. You will be working on pre and post-silicon system development activities to achieve full operation and optimization of PHY/L1 modules such as AGC, DPD, advanced time-domain processing, channel estimation, demodulation, and decoding, in a highly complicated wireless communication device. We are looking for a highly reciprocal individual who can excel in performing the integration of these modules in the system with a comprehensive full-stack understanding and with the ability to analyze issues in the lab and field, which are related to L1, MAC, and RRC procedures, with tight multi-functional work with RF, HW, FW, and SW teams.

BSc in EE or Physics
5 years of experience in signal processing, parameter estimation, and stochastic signal processing
Hands-on experience in lab testing, characterization, and field certifications
In-depth knowledge of cellular communication standards: 5GNR, 4G LTE, and the corresponding L1/MAC/RRC procedures such as PLMN/Cell search, hand over, re-selection, measurements, random access procedures, registration, etc.
Full-stack system-level understanding and ability to comprehend and effect an improvement to multi-disciplinary processes of RF/PHY/L1/L2 and L3
Experience with Matlab, C/C++, and/or Python for algorithm modeling (floating-point and fixed-point), link-level simulation, and lab testing environments.
Good understanding and debug capabilities of a mixed HW/FW multi-processor PHY/L1 implementation
Experience in chip bring-up and lab equipment, such as protocol testers, spectrum analyzers, signal generators, power meters, etc.
Strong analytical skills (linear algebra, random processes, detection, and estimation, etc.)

Hands-on experience in developing machine learning projects - a plus
MSc or PhD - an advantage
