Wireless SoC RF Integration and Validation Engineer

Come and join Apple’s growing wireless silicon development team. Our wireless SoC organization is responsible for all aspects of wireless silicon development, emphasizing highly energy-efficient design and new technologies that transform the user experience at the product level. All of this is driven by a world-class vertically integrated engineering team spanning RF/Analog architecture and design, Systems/PHY/MAC architecture and design, VLSI/RTL design and integration, Emulation, Design Verification, Test and Validation, and FW/SW engineering. In this role, and as part of our team, you will deliver an RF integration end-to-end Solution, which includes DUT control development, pre-silicon emulation/simulation, integrated RF calibration. You will become a central hub which enables different phases from design development toward Apple product’s mass production. You will also be responsible for Wireless SoC-RF Bring up at the first touch, final Silicon validation results and compliance. You will get the opportunity to keep developing your technical depth in both HW and SW domains, such as understanding of wireless transceiver architecture, RF system and DSP knowledge, Software framework, RF driver and embedded system, and experience of delivery Apple products until productization.

Your responsibilities include but are not limited to:

• Develop and integrate RF end to end DUT control sequence and then verify it with emulation system.
• Responsible for wireless-SOC RF functionality bring up.
• Design and develop RF block and/or system calibrations including algorithms and optimizations.
• RF performance optimization and characterization such as Psat, Mask, IP3, NF, ACPR, phase noise, lock time, return loss.
• Design RF test bench and implement scripts which controls wireless-SOC and communicate test equipment.
• Writing scripts that plot, parse and analyze large data sets.
• Generate RF performance summary report based on characterization results again chip specification.
• Develop RF Calibrations and tests for Wafer ATE and Module ATE mass productions and analyze ATE failures.
• Develop RF FW based on python reference script.

• Minimum requirement of a bachelors degree
• Solid experience of RF parametric testing, such as IP3, NF, ACPR, phase noise, load pull.
• Strong working knowledge of RF test equipments, such as; network analyzer, spectrum analyzer, vector signal analyzer, vector signal generator.
• Strong Wireless RF background and familiarity with RF systems fundamentals, RF transceiver architectures and/or digital communication.
• Proficiency with understanding RFIC block-level design schematics.
• Some experience of RF PCB board design, debug, and development.
• Python programming language is highly desired.
• Experience with embedded system and C programming language is preferred.
• Automation framework development.
