At Apple, we work every single day to craft products that enrich people's lives. We are seeking a forward-thinking and unusually hardworking Wireless System Engineer to join our multifaceted group. In this technical role, you will have the extraordinary opportunity to craft upcoming products that will delight and encourage millions of Apple's customers. Your responsibilities will include physical layer system design, integration, and characterization of state-of-the-art wireless SoC products from conception to production. You will implement system models for the wireless communication system, addressing RF/circuit impairments, and design, simulate, and implement advanced physical layer wireless communication algorithms. You will design algorithms for calibration, pre-equalization, cancellation, and/or pre-distortion techniques to achieve efficient and robust performance across a large number of parts, systems, and wireless channels. Your role will also involve implementing fixed-point models and performing detailed performance investigations to allow performance sign-off and enable RTL bit-exact development. You will collaborate with digital designers to realize PHY algorithms using power and area-efficient digital implementations, and with firmware designers to implement high-efficiency software implementations and hardware acceleration. Additionally, you will validate and characterize algorithms on real silicon alongside RFIC and digital circuit designers and automation/test engineers. Your work will include bringing up and taking to production state-of-the-art physical layer wireless communication system algorithms for very high data rate applications. You will design firmware-based algorithms involving MAC-PHY interactions and SW-based PHY configurations, implementing codes in Python and firmware. Developing test plans and working with automation/test engineers to implement these plans, collect and analyze test results, and identify and debug issues will also be part of your responsibilities.
