At Apple, new ideas have a way of becoming extraordinary products, services, and customer experiences very quickly. 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.\nOur 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 our shift to agentic engineering, scaling validation throughput with AI agents without compromising the quality bar, to enable uncompromised connectivity in future Apple products.\nDescription\nAs an RF TX 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.\nMinimum Qualifications\nStrong cross-functional leadership skills; ability to communicate complex technical findings clearly to Chip Design, Firmware, System Engineering and System Validation teams.\nExpertise in Python for test automation and data analysis (NumPy/Pandas), and demonstrated experience working with AI coding agents beyond script generation: delegating multi-step tasks, defining acceptance criteria, and validating agent output against specifications.\nProven track record in systematically debugging complex silicon issues and isolating root causes across hardware, firmware, or test setups.\nPreferred Qualifications\nDeep understanding of RF transceiver architecture with specific expertise in cellular transmitter architecture and key metrics like ACRL, SEM, EVM and Cross-Talk Isolation.\nMastering requirements for cellular standards (e.g. 5G NR, LTE) and mixed-signal building blocks (ADCs/DACs) is highly desirable.\nExperience with 3GPP spectrum emission and network signalling requirements is definitely a plus.\nHands-on mastery of RF lab equipment including Spectrum/Phase Noise Analyzers, VNAs, and high-speed Oscilloscopes.\nMaster's or PhD in Electrical Engineering or equivalent with 5+ years of relevant experience in RF/Mixed-Signal validation, system engineering or design.","description_format":"text","description_chars":2468,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":true},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Operating
