• Strong, demonstrable hands-on expertise in physical layer (PHY) and radio frequency (RF) theory, principles, and architectures.
• Deep practical proficiency in analyzing OFDM systems, RF impairments, IQ imbalance, and calibration algorithms.
• Proven operational experience in laboratory equipment operation (spectrum analyzers, signal generators, vector network analyzers).
• Exceptional analytical, troubleshooting, debugging, and problem-solving capabilities under complex hardware test conditions.
• Excellent written and verbal English communication skills with strong cross-functional collaboration abilities.
• Mandatory legal work eligibility and physical availability for full-time on-site operations at Apple (Sunnyvale, San Diego, or Irvine).
• Advanced degree focusing on wireless communications, RF integrated circuits, or signal processing.
• Prior professional working experience in top-tier semiconductor companies, wireless chipset vendors, or major consumer electronics enterprises.
• Proficiency in programming and scripting languages (Python, MATLAB, C++) for automated test and data analysis.
• Familiarity with cellular (5G/4G) or connectivity (Wi-Fi/Bluetooth) standards and protocol stacks.

Responsibilities

• Lead silicon bring-up, hardware-software integration, and physical layer (PHY/RF) validation across advanced wireless chips.
• Investigate and resolve complex technical challenges involving OFDM, RF impairments, phase noise, and IQ imbalance.
• Design, develop, and optimize advanced calibration algorithms and automated measurement routines for silicon testing.
• Perform rigorous PHY/RF analysis, link-budget evaluations, and RF performance characterization in laboratory environments.
• Collaborate seamlessly with silicon design, systems engineering, RF/PHY firmware, and cross-functional hardware squads.
• Author meticulous technical documentation, test plans, validation reports, and integration architecture specifications.
• Drive continuous improvement in wireless integration methodologies, test coverage, and lab automation infrastructure.
• Mentor junior engineers and provide technical leadership across multidisciplinary wireless systems teams.
