System Test Engineer, 5G/6G Wireless Interoperability - Wireless Technologies and Ecosystems

At Apple, we push the boundaries of what’s possible - and that starts with the engineers who test it. As a System Test Engineer on our Wireless Technologies team, you’ll play a pivotal role in ensuring Apple devices deliver seamless, world-class 5G and 6G connectivity across every network, every carrier, and every corner of the globe. If you thrive at the intersection of deep protocol knowledge and cutting-edge innovation, this is where your expertise will shape products used by hundreds of millions of people.

• Master’s degree (MS) in Electrical Engineering, Computer Engineering, Telecommunications, or a related field
• 3+ years of hands-on experience in wireless system testing, interoperability testing, or protocol validation
• Deep knowledge of 3GPP standards including 5G NR physical layer (FR1 and FR2/mmWave), RRC, NAS, and related protocols
• Proficiency in scripting and automation (Python, shell, or similar) for test development and result analysis
• Experience with AI/ML tools for test data analysis, anomaly detection, or tool development
• Familiarity with lab test equipment such as network emulators, protocol analyzers, and signal analyzers, * Experience with 6G research concepts, IMT-2030 frameworks, or pre-standard wireless technologies
• Hands-on experience with carrier interoperability testing and field trial environments
• Knowledge of 5G core network architecture (5GC), network slicing, and SA/NSA deployment modes
• Experience with iOS or embedded platform debugging and log analysis tools
• Background in RF performance testing including beam management, MIMO, and FR2 mmWave characterization
• Familiarity with test management and CI/CD pipelines for continuous test integration
• Strong cross-functional communication skills with the ability to present technical findings to diverse audiences

In this role, you will be at the forefront of validating next-generation wireless connectivity on Apple products through rigorous interoperability testing across 5G and emerging 6G standards. You will collaborate with cross-functional teams spanning silicon, software, and RF engineering to design and execute system-level test strategies that span physical layer performance to end-to-end protocol behavior. Working with global carrier partners and industry standards, you’ll leverage AI/ML-driven tooling and scalable automation frameworks to uncover issues early and drive quality to the highest bar - all in pursuit of delivering the best possible wireless experience to Apple customers worldwide.
