About The Position
Apple is seeking an experienced RF engineer to lead validation of complex phase-locked loop (PLL) and frequency-synthesis subsystems in monolithic cellular transceivers. The role owns bring-up and characterization of frequency-generation subsystems and works cross-functionally with Design, Firmware, and System teams to ensure silicon meets rigorous specifications. The engineer defines validation strategies, executes complex measurements, analyzes performance against specifications, and helps debug hardware and software issues. The role also advances agentic engineering by using AI agents to scale validation throughput while maintaining quality. This includes articulating specifications and acceptance criteria, delegating implementation to AI agents, and verifying results through deterministic checks and independent reviews. The engineer develops scalable, well-documented automation frameworks and data-analysis tools for engineers and AI agents, and communicates technical results clearly across teams.
Requirements
- Master’s or PhD in Electrical Engineering or equivalent.
- 5+ years of relevant experience in RF/mixed-signal validation, system engineering, or design.
- Deep understanding of RF transceiver architecture, including cellular transmitter architecture and metrics such as ACRL, SEM, EVM, and cross-talk isolation.
- Expertise in Python for test automation and data analysis, including NumPy and Pandas.
- Demonstrated experience using AI coding agents beyond script generation, including delegating multi-step tasks, defining acceptance criteria, and validating outputs against specifications.
- Proven ability to systematically debug complex silicon issues and isolate root causes across hardware, firmware, or test setups.
- Hands-on mastery of RF laboratory equipment, including spectrum/phase-noise analyzers, VNAs, and high-speed oscilloscopes.
- Strong cross-functional leadership and ability to communicate complex technical findings clearly to Chip Design, Firmware, System Engineering, and System Validation teams.
Nice To Haves
- Mastery of cellular standards requirements such as 5G NR and LTE.
- Knowledge of mixed-signal building blocks such as ADCs and DACs.
- Experience with 3GPP spectrum-emission and network-signalling requirements.
Responsibilities
- Lead validation of complex PLL and frequency-synthesis subsystems.
- Own bring-up and characterization of frequency-generation subsystems in cellular transceivers.
- Define validation strategies, execute complex measurements, and analyze performance against specifications.
- Develop efficient validation solutions and clearly articulate specifications and acceptance criteria.
- Delegate multi-step implementation tasks to AI agents and verify their output using deterministic checks and independent reviews.
- Develop scalable, well-documented automation frameworks and data-analysis tools usable by engineers and AI agents.
- Report technical results clearly and work cross-functionally to debug hardware and software issues.
- Drive technical solutions with Design, Firmware, and System teams to ensure silicon meets specifications.
