About The Position

Do you have a passion for building innovative HW/SW for controlling modern RF transceivers? Do you enjoy hands-on, cradle-to-grave experience for building innovative cellular SoCs? In this role, you will have the opportunity to engage in architecture stages, and work with various teams to design, implement, verify, validate, bring-up, and productize sophisticated transceiver architectures. Join us and help to innovate new wireless systems technologies that continually outperform the expectations! By collaborating with other product development groups across Apple, you’ll push the industry boundaries of what wireless systems can do and improve the product experience for our customers across the world! As a Cellular System Engineer, you will be responsible for the pre- and post-silicon bring up, and validation of end-to-end cellular systems. You will understand and map systems algorithms and requirements to HW/FW architecture, simulation and emulation based validation of the control flows and algorithms. This position requires strong collaboration with SoC, PHY, RF HW, RF FW, and SW teams to ensure the end-to-end system requirements are met. You will also have a critical hands-on role in pre- and post-silicon verification, validation, and bring-up of silicon, to support productization.

Requirements

• BS and a minimum of 10 years relevant industry experience.
• Strong understanding of communication theory and signal processing, AGC, beamforming, Tx power control, mitigation of radio impairments, and calibration algorithms.
• Strong experience with Matlab, Python, and C/C++ and efficient analysis and automation scripting.
• Excellent communication skills, both written & verbal especially in a multi-functional environment.
• Demonstrate strong clarity of thought and strong analytical and problem-solving skills.

Nice To Haves
