As a Wireless Systems Integration Engineer at Apple, you will play a critical role in the design, integration, and productization of advanced wireless communication systems. Your primary focus will be on implementing cancellation and pre-distortion techniques to ensure optimal performance across various parts, systems, and wireless channels. You will be responsible for developing and validating golden calibration algorithms for wireless transceivers within automation infrastructure, ensuring that these algorithms are tested and characterized on real silicon in collaboration with PHY, MAC, RFIC, and digital circuit designers. Your work will involve bringing state-of-the-art physical layer wireless communication system algorithms to production, particularly for high data rate applications. In this position, you will design and implement the necessary infrastructure for chip bring-up, including chip drivers, debug tools, and automation environments. You will also develop and execute comprehensive test plans, collect and analyze test results, and identify and debug issues that arise during the testing process. A key aspect of your role will be championing automation throughout the bring-up, tuning, characterization, and other phases of post-silicon chip development, ensuring that processes are efficient and effective. To succeed in this role, you will need extensive experience in system design and integration, as well as a deep understanding of communication theory and signal processing algorithms. Your proven skills in system bring-up, integration, characterization, and debugging of wireless silicon in a lab environment will be essential. You will also need to be familiar with lab equipment such as spectrum analyzers and signal generators, and have experience in developing test automation tools and scripts. Knowledge of existing wireless communication protocols, along with proficiency in programming languages such as Matlab, Python, Shell scripting, and C/C++, will be critical for your success.
