Job description

OS Power and Performance - Software Development Engineer in Test

San Diego, California, United States Software and Services

Every meaningful decision about Apple device health, from identifying a battery regression to validating a new AI feature's system footprint, starts with data. The Platform Telemetry Quality Engineering team owns the automated systems that ensure that data is accurate, complete, and trustworthy across every Apple platform. We sit at the foundation of Apple's quality signal, and we're looking for engineers who understand that great products are only as good as the data behind them.

Description

As a Quality Engineer on our team, you'll build and maintain the automated pipelines that validate system telemetry data across Apple's entire device lineup, iPhone, iPad, Mac, Apple Watch, Apple Vision Pro, and beyond. Your work ensures that when engineers across Apple instrument new features and services, the data flowing back from devices is correct, well-structured, and regression-free. You'll validate telemetry from some of Apple's most ambitious software, including on device AI models and Siri intelligence, working directly with development teams to define quality expectations before data ever reaches production. Through dashboards, automated reporting, and close cross-functional collaboration, you'll give teams across the organization a clear, real-time picture of system health at every point in the release cycle. This role is for someone who takes data seriously, builds with scale in mind, and wants their work to underpin the quality signal for one of the world's most complex software ecosystems.
