Senior Wireless System Engineer - Radio

San Diego,California,United States

Hardware

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, taking care of challenges from the complex usages, more demanding performances, and reliabilities to enable emerging wireless applications and products. Our goal is to come up with innovative architectures and protocols, integrated systems and algorithms with employing the advanced technologies to introduce our innovative products, providing evolutions to our lives. In this technical role, you will be at the center of a silicon design group, with a critical impact on radio architecture, radio system performance, system integration and physical layer algorithms designs. You will develop system model of RF/analog design, radio chain modeling, integrated radio interaction models, dynamic behavior models and assess associate impairments. You will evaluate radio performance on various application scenarios, as well as working on architecting various calibration and correction methods for radio impairments. This role requires collaboration with HW digital designers and architects, products, Radio, analog designers, and SW engineers, to define and specify the wireless systems.

Key Qualifications

• We'd like you to have:

• Deep understanding of RF and analog components/modules composited of wireless communication systems, the possible impairments from those components, and the corresponding calibration and impairment reduction methods/algorithms.

• Strong understanding of communication theory, information theory and signal processing related algorithms design.

• Proven track record of optimization algorithm and its applications to RF calibration.

• Strong analytical capability to develop best-in-class solution in terms of performance, power and area, for the meaningful issues of physical layer design.

• Experience with MATLAB, Python and/or C/C++ for algorithm development, modeling and simulation.

• Hands-on experience on lab testing and characterization, such as spectrum analyzer, signal generator, signal analyzer, power meter, etc.

• Knowledge in existing protocols: 5G/LTE/WCDMA/GSM, 802.11a/b/g/n/ac/ax/be, 802.11ad/ay or Bluetooth/BLE

• Circuit design experience / knowledge is a plus

Description

In this role, core responsibilities include, but are not limited to, the following: •Design radio models for the wireless communication system, RF/circuits impairments. Design method/algorithm to alleviate those impairments by calibration, pre-equalization, canceller, and/or pre-distortion techniques. •Evaluate radio performance in different scenarios by quantitative analysis and link simulation. •Work with radio designer to come up with state-of-art radio architecture. •Work with digital designers to realize PHY/radio algorithms with power and area efficient digital implementations. •Work with firmware designers to realize PHY/radio algorithms with high efficiency software implementation, and possibly with hardware acceleration. •Responsibility for Bring up, test, characterize and optimize real silicon in lab.

Education & Experience

BS and 10+ years of relevant experience required. MSEE/PhD preferred
