Wireless Systems Integration Engineer, RFPHY

At Apple we work every single day to craft products that enrich peoples lives. 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 Wireless Connectivity team you will have the rare and extraordinary opportunity to craft upcoming products that will delight and encourage millions of Apples customers every single day.

In this role you will play a key part in the integration bring-up and tuning of physical layer/RF systems for next-generation wireless SoCs - from pre-silicon stage to product launch in Apple devices. You get to collaborate across disciplinesincluding PHY algorithms RF design digital MAC and firmware teams - to ensure seamless integration and best-in-class wireless performance.

Drive Bring-up integration and performance optimization of Wi-Fi PHY and Radio Systems for both pre-silicon and post-silicon and integrate PHY features and calibration algorithms such as TPC AGC TSSI RSSI and interference and root-cause system performance issues across RF domains (impairments calibration gain control) and digital PHY processing (OFDM synchronization channel estimation MIMO).nCollaborate closely with PHY system Algorithm Engineers as well as Radio RFIC MAC and digital circuit designers to ensure end-to-end feature the transition from lab bring-up to robust firmware integration and product RF/PHY performance and drive resolutions to ensure robust high-quality product delivery.

BS and a minimum of 10 years relevant industry experiencenHands on experience in Experience in wireless system design integration or fundamentals in signal processing communication theory OFDM systems radio architectures and analog/RF impairments with understanding of their impact on key system performance metrics.

Preferred MSEE or PHD with 3 years relevant industry experiencenExperience knowledge and skills on wireless system design integration bring up and debug of wireless PHY and RF systems on SoC understanding of OFDM and MIMO-based wireless systems across both baseband and RF domains with a solid foundation in related communication theory and signal understanding of wireless transceiver architectures RF front-ends and related system-level of analog/RF impairments (e.g. DCOC IQ imbalance IP2 LOFT DPD) and their calibration in performance metrics such as EVM sensitivity and impairment mitigation working across multi-radio coexistence using and understanding of the theory of operation of lab equipment such as spectrum analyzer signal generator power with at least one of the following - Matlab Python Shell scripting and/or C/ with automation infrastructure development including traceability repeatability and related tools (GIT CI database reporting tools).nKnowledge of existing wireless communication protocols: 802.11a/b/g/n/ac/ax/be LTE/WCDMA/GSM or 802.11ad/ degrees - MS or PhD in Electrical Engineer Computer Engineering or other technical disciplines
