## 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., Design and implement automated tests that verify system telemetry data is logging correctly, completely, and without regression across Apple's full device and platform portfolio

Review and qualify telemetry contributions from development teams, validating table structure, data completeness, null handling, and correctness before changes land in production

Validate telemetry from on-device AI features, including large language model inference and Siri intelligence workflows, ensuring the data produced meets Apple's quality bar

Build and maintain automation infrastructure that runs telemetry validation at scale across multiple platforms simultaneously

Develop dashboards and reporting pipelines that surface telemetry health signals to engineering and program stakeholders in real time

Triage and investigate telemetry regressions, coordinating with development teams to drive issues to resolution quickly

Improve the tooling that automates the path from developer telemetry submission to validated, integrated test coverage

Identify gaps in coverage across new devices, platforms, and features, and build the automation to close them
