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? 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.
Description
In this role you will play a key part in the integration, bring-up, and tuning of physical layer systems for next-generation wireless SoCs - from pre-silicon stage to product launch in Apple devices.
As a hands-on technical contributor, you will be at the forefront of bring-up, integration and tuning, and debugging of advanced PHY and radio systems for state-of-the-art wireless SoCs. You’ll collaborate across disciplines—including PHY algorithms, RF design, digital, MAC, and firmware teams - to ensure seamless integration and best-in-class wireless performance.
Minimum Qualifications
BS and a minimum of 3 years relevant industry experience
Experience in wireless system design, integration, or bring-up.
Preferred Qualifications
Experience, knowledge and skills on wireless system design, integration, bring up and debug of wireless PHY and RF systems on SoC platforms.
Strong understanding of OFDM and MIMO-based wireless systems across both baseband and RF domains, with a solid foundation in related communication theory and signal processing.
Strong understanding of wireless transceiver architectures, RF front-ends and related system-level tradeoffs.
Knowledge of analog/RF impairments (e.g., DCOC, IQ imbalance, IP2, LOFT, DPD) and their calibration flows.
Proficiency in performance metrics such as EVM, sensitivity and impairment mitigation strategies.
Experience working across multi-radio coexistence environments.
Proficiency using and understanding of the theory of operation of lab equipment (spectrum analyzer, signal generator, power meter).
Experience with at least one of the following: Matlab, Python, Shell scripting and/or C/C++.
Experience with automation infrastructure development (traceability, repeatability) and related tools (GIT, CI, database, reporting tools).
Knowledge of existing wireless communication protocols: 802.11a/b/g/n/ac/ax/be, LTE/WCDMA/GSM, or 802.11ad/ay.
Advanced degrees - MS or PhD in Electrical Engineer or Computer Engineering.
Responsibilities
Transmit and receive chain bring-up, tuning, and performance optimization for both pre-silicon and post-silicon stages.
Develop and integrate PHY features and calibration algorithms such as TPC, AGC, TSSI, RSSI, and interference mitigation.
Implement and validate chip control drivers and reference designs in bring-up and emulation environments.
Conduct pre-silicon emulation-based bringup, integration and validation of the PHY system.
Collaborate closely with PHY system Algorithm Engineers as well as Radio, RFIC, MAC and digital circuit designers to ensure end-to-end feature integration.
Supporting the transition from lab bring-up to robust firmware integration and product readiness.
Characterize performance, analyze data, root-cause system-level issues, and ensure high product quality.
