RF TX Silicon Validation Engineer (m/f/d) #200693152 in München

Summary

Imagine what you could do here. 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.

Our team is responsible for validating the RF performance of top-notch, monolithic cellular transceivers. We are looking for an experienced and passionate RF engineer to define validation strategies and execute the validation of complex cellular transmitter systems. 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 performance in future Apple products.

Description

As 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.

Responsibilities

• Defining validation strategies, executing complex measurements, and analyzing performance against specifications.
• Architecting efficient validation solutions, articulating clear specs and acceptance criteria, delegating implementation to AI agents, and verifying results with deterministic checks and independent reviews.
• Developing scalable automation frameworks and data analysis tools that are well documented and usable by both engineers and AI agents.
• Reporting technical results clearly and in a cross functional team to debug hardware and software issues, ensuring the highest quality for Apple's wireless products.

Minimum Qualifications

• Strong cross-functional leadership skills; ability to communicate complex technical findings clearly to Chip Design, Firmware, System Engineering and System Validation teams.
• Expertise 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.
• Proven track record in systematically debugging complex silicon issues and isolating root causes across hardware, firmware, or test setups.

Preferred Qualifications

• Deep understanding of RF transceiver architecture with specific expertise in cellular transmitter architecture and key metrics like ACRL, SEM, EVM and Cross-Talk Isolation.
• Mastering requirements for cellular standards (e.g. 5G NR, LTE) and mixed-signal building blocks (ADCs/DACs) is highly desirable.
• Experience with 3GPP spectrum emission and network signalling requirements is definitely a plus.
• Hands-on mastery of RF lab equipment including Spectrum/Phase Noise Analyzers, VNAs, and high-speed Oscilloscopes.
• Master's or PhD in Electrical Engineering or equivalent with 5+ years of relevant experience in RF/Mixed-Signal validation, system engineering or design.
