Wireless System and Algorithm Design Engineer

Summary

Posted: Aug 20, 2024

Role Number: 200534283

Would you like to join Apple's growing wireless silicon development team? Our wireless SOC organization is responsible for all aspects of wireless silicon development, tackling challenges from complex usages to demanding performances and reliabilities to enable emerging wireless applications and products. In this technical role, you will be at the center of a silicon design group, responsible for physical layer and cross-layer algorithms designs for innovative wireless communication systems that require low latency, very high data rates, high efficiency, reliability, and low power consumption. You will apply signal processing, communication and information theory, probability, and random processes techniques to architect and design innovative algorithms for the receiver and transmitter.

Description

In this role, you will demonstrate strong analytical skills, innovative thinking, and fundamental knowledge to design creative algorithms, innovative architectures, and protocols to resolve challenges and develop best-in-class solutions in terms of performance, power, and area. You will collaborate closely with HW digital designers and architects, RF/analog designers, and SW teams to define and specify wireless systems.

Core Responsibilities:

1. Design and simulate innovative wireless communication systems to enable emerging applications and wireless system products.
2. Implement system models and investigate innovative algorithms for performance enhancements, design, and validate them to allow performance sign-off and enable RTL development.
3. Implement system models for the wireless communication system, RF/circuit impairments. Design methods/algorithms to alleviate those impairments by calibration, pre-equalization, canceller, and/or pre-distortion techniques.
4. Define the control procedures of the physical layer hardware modules to achieve robust and optimal performance of the Modem in congested radio environments with co-existing wireless communication systems.
5. Work with digital designers to realize these methods with power and area-efficient digital implementations.
6. Work with firmware designers to realize these methods with high-efficiency software implementations, and possibly with hardware acceleration.
7. Bring up, test, characterize, and optimize real silicon in the lab.

Key Qualifications

• Extensive experience in designing and developing physical layer core algorithms, such as MIMO signal estimation and detection, channel estimation, equalization, coding theory, beamforming, timing recovery, frequency synchronization, and automatic gain control.
• Track record in applying innovative signal processing, communication theory, and information theory techniques to resolve challenging problems of physical layer design for modern wireless communication systems.
• Deep understanding of communication theory, information theory, and signal processing related algorithms design.
• Strong analytical capability to develop best-in-class solutions in terms of performance, power, and area.
• Deep understanding of components/modules of wireless communication systems and the possible impairments from those components, along with corresponding calibration and impairment reduction methods/algorithms.
• Algorithm development experience with hardware and firmware-friendly designs.
• Proficiency in C/C++ and Matlab for algorithm development, modeling, and simulation of the physical layer.
• Knowledge of existing protocols: 5G/LTE/WCDMA/GSM, 802.11a/b/g/n/ac/ax/be, 802.11ad/ay, or Bluetooth/BLE.

Education & Experience

BS and 3+ years of relevant experience required. MS and PhD preferred.
