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.

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.
