Responsibilities

• 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.
• 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.
