About the Job

Requirements

  • A Master's degree or foreign equivalent in Electrical and Computer Engineering or a related field.
  • Experience and/or education must include full-cycle physical design and layout of sub-micron radio-frequency integrated circuits to identify potential interactions among radio-frequency components and drive system-level design improvements.
  • Experience and/or education must include performing failure analyses to identify and resolve complex system-level hardware issues during development, and conducting hands-on rework, including soldering, tuning, and reassembly, to evaluate mockups and close performance gaps.
  • Experience and/or education must include architecture of microwave signal chains, link budget analysis, and electromagnetic simulation of phased array antennas.
  • Experience and/or education must include a strong fundamental understanding of radio-frequency integrated circuit and radio-frequency system design principles.
  • Experience and/or education must include circuit design and signal integrity design, validation of analog/mixed-signal blocks such as analog-to-digital converters and digital-to-analog converters, and characterization of Error Vector Magnitude and quantization noise.
  • Experience and/or education must include configuring radio-frequency test equipment, including callboxes, signal generators, and signal analyzers, to conduct measurements and debug hardware issues.
  • Experience and/or education must include collaborating with vendors to improve radio-frequency grounding, mitigate electromagnetic interference, and drive mass-production solutions.
  • Experience and/or education must include experience on at least one radio technology among Cellular, GPS, Bluetooth, Wi-Fi, Thread, NFC, and UWB.

Responsibilities

  • Develop wireless products with a focus on multi-radio coexistence design.
  • Define coexistence performance requirements and test methodology to ensure Apple products meet those requirements.
  • Work with cross-functional teams, vendors, contract manufacturers, and technology suppliers.
  • Provide design guidelines, review printed circuit board and flex layouts, and debug and resolve multi-radio coexistence issues.
  • Support manufacturing test and debug failure units, and perform large-sample failure analysis.
  • Participate in developing system mitigation that optimizes product performance.
  • Analyze root causes of parametric test failures and suboptimal test results.
  • Use spectrum analyzers, base station emulators, and network analyzers to measure and analyze radio-frequency signals in mobile devices.
  • Identify causes of test failures or suboptimal test results efficiently, and anticipate performance issues based on test results.
  • Provide integration recommendations to optimize overall radio-system performance quality in the wireless device.
  • Travel internationally 15% of the time.
