Bring passion, dedication, and a no-excuse mindset to your job and there's no telling what you could accomplish. Smart people and inspiring, innovative technologies are the norm here. Our team is responsible for validating the RF performance of top-notch, monolithic cellular transceivers. We are looking for an experienced RF engineer to lead the validation of complex PLL and frequency synthesis subsystems. In this role, you will work cross functionally with Design, Firmware, and System teams to ensure our silicon meets rigorous specifications. You will drive the adoption of modern automation workflows to enable un-compromised connectivity in future Apple products.

DESCRIPTION

As an RF PLL Silicon Validation Engineer, you will own the bring-up and characterization of frequency generation subsystems in market-leading transceivers. Your work style is collaborative and proactive, driving technical solutions across interdisciplinary teams.

MINIMUM QUALIFICATIONS

Strong cross-functional leadership skills; ability to communicate complex technical findings clearly to Chip Design, Firmware, and System Verification teams. Expertise in Python for test automation and data analysis (NumPy/Pandas), with a strong focus on using AI-powered coding assistants to accelerate workflow and script generation. Proven track record in systematically debugging complex silicon issues and isolating root causes across hardware, firmware, or test setups. Hands-on mastery of RF lab equipment including Spectrum/Phase Noise Analyzers, VNAs, and high-speed Oscilloscopes.

PREFERRED QUALIFICATIONS

Deep understanding of RF transceiver architecture with specific expertise in frequency synthesis (PLLs, DCOs) and key metrics like Phase Noise, Lock Time, and Cross-Talk Isolation. Experience with cellular standards (5G NR, LTE) and mixed-signal building blocks (ADCs/DACs) is highly desirable. Master’s or PhD in Electrical Engineering or equivalent with 5+ years of relevant experience in RF/Mixed-Signal validation or design.
