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.

In this technical role, you will be part of a silicon design group responsible for system integration, design of radio calibration algorithms, chip bringup, and characterization of state-of-the-art wireless SoC products from conception to production.

We are looking for an exceptional engineer with experience in designing novel calibration algorithms for wireless systems.

  • Bringup, validate, and tune WiFi PHY/Radio systems on emulation, FPGA and real silicon platforms.
  • Design and implement optimal algorithms for calibration of IQ imbalance, DC Offset, LO feed through and other radio impairments in a Python/Matlab simulation environment to benchmark performance.
  • Work alongside PHY, FW, RFIC and digital HW designers on efficient implementation of algorithms for both factory tuning and real time operation.
  • Develop and implement test plans; collect and analyze test results; identify and debug issues.

Minimum requirement of a bachelors degree

  • Hands-on experience with chip bringup, tuning wireless transmitter or receiver chain for optimal performance, and familiarity with calibration algorithms.
  • Basic understanding of communication theory, DSP, OFDM systems, radio architectures, radio impairments and its impact on performance.
  • Experience with Python, Matlab and/or C/C++ implementation.
  • Good understanding of communication theory and signal processing algorithms (such as timing recovery, signal estimation and detection, automatic gain control, RF impairment estimation and correction, coexistence).
  • Knowledge of wireless communication protocols like IEEE 802.11 standards or LTE.
  • Experience designing algorithms for calibration, pre-equalization or digital pre-distortion techniques.
  • Hands-on experience using wireless test lab equipment (spectrum analyzer, signal generator, network analyzer, power meter).
  • Excellent analytical and debug skills.
  • Experience building test automation and verification flow development with scripting languages such as Python.
