Wireless PHY System Engineer

At Apple, we work every single day to craft products that enrich people’s lives. Do you love working on challenges that no one has solved yet? As a member of our Wireless Silicon Design group, you will have the unique and rewarding opportunity to develop upcoming and future generations of products to support emerging applications that will delight and encourage millions of Apple’s customers every single day! 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. In this role, you will be responsible for bringup, integration and tuning of PHY/Radio on internal silicon solutions from pre-silicon, through bringup, and until shipping in your favorite Apple products.DescriptionIn this individual technical contributor role, you will be responsible for the pre- and post-silicon bringup of key PHY and radio system for state-of-the-art wireless SOC products. Your responsibilities will include: Transmit and receive chain bringup, tuning, and debug; optimizing PHY and calibration algorithms such as TPC, AGC, TSSI, RSSI, interference mitigation and others. You will collaborate closely with other PHY systems and algorithm engineers as well as MAC, Radio, and digital circuit designers. You will develop chip control drivers and reference implementations in the bringup environment and working closely with firmware engineers to integrate these algorithms into the firmware. You will also guide and assist the characterization team in identifying and resolving reported issues.Minimum QualificationsBS and 5+ years of relevant experienceExperience, knowledge and skills on wireless system design, integration, bring up, characterization and debug of wireless communication systems, ideally on an SOCProficiency in wireless transceivers, RF front-end architectures and performance tradeoffsProficiency in system-level parametrics, such as EVM and Sensitivity, and impairment mitigationUnderstanding of communication theory and signal processing related algorithms (such as timing recovery, signal estimation and detection, automatic gain control, RF impairment estimation and correction, channel estimation, equalization)Proficiency using and understanding of the theory of operation of lab equipment (spectrum analyzer, signal generator, power meterExperience with at least one of Matlab, Python, Shell scripting and/or C/C++ is requiredExperience with automation infrastructure development (traceability, repeatability) and related tools (GIT, CI, database, reporting tools)Knowledge in existing wireless communication protocols: 802.11a/b/g/n/ac/ax/be, LTE/WCDMA/GSM, or 802.11ad/ayPreferred QualificationsPreferred advanced degrees MS or Ph.D in Electrical Engineer or Computer EngineeringSubmit Resume
