Do you love working on challenges that no one has solved yet? Do you like changing the game? We have an opportunity for a forward-thinking and unusually hardworking Wireless System Engineer. As a member of our multi-faceted group, you will have the rare and extraordinary opportunity to craft upcoming products that will delight and encourage millions of Apple’s customers every single day.\nDescription\nIn this technical role, you will be part of a dynamic group and have the rare and extraordinary opportunity to craft products that will delight and encourage millions of Apple’s customers. You will be responsible for System integration and characterization of state-of-the-art wireless SoC products, as well as bringup & integration of the PHY/Radio and executing the PHY and radio level characterization on internal silicon solution from chip back until shipping in your favorite Apple products. You will engage with the first silicon arrives to bringup, integrate, tune and debug the PHY and radio system operation and performance. You will use your understanding of communication theory and radio calibration algorithms to optimize performance and debug issues on the silicon. Your experience using and understanding the test equipment to identify and zero in on issues and your software skills to configure and probe the chip. As an owner of the silicon performance, you will be key in making sure Apple products exceed expectations.\nMinimum Qualifications\nBS and a minimum of 3-10 years relevant industry experience\nStrong fundamentals in RF/PHY systems, signal processing, communication theory, and analog impairments - with practical expertise in their application to OFDM-based transceivers.\nPreferred Qualifications\nPreferred MSEE or PHD degree with some relevant experience\nKnowledge in existing wireless communication protocols: 802.11a/b/g/n/ac/ax/be, LTE/WCDMA/GSM, or 802.11ad/ay.\nUnderstanding communication theory and key Tx/Rx metrics like EVM and sensitivity.\nExperience bringing up radio calibration algorithms (such as Power Control, IQ imbalance, LO Leakage, TSSI or others).\nExperience in system bring-up, integration, characterization, and debug of real wireless silicon in a lab.\nExperience using and understanding of the theory of operation of wireless/RF test equipment such as signal analyzer, signal generator, and spectrum analyzer.\nExperience developing test automation including equipment drivers, debug tools, automation scripts, database interfaces, and reporting tools.\nExperience with Python, Matlab, Perl, C/C++, or C#.\nExperience with automation infrastructure development (traceability, repeatability) and related tools (GIT, CI, database, reporting tools).\nPreferred advanced degrees MS or Ph.D in Electrical Engineer or Computer
