Software Integrity Engineer, CoreMotion, Sensing & Connectivity

The CoreMotion team builds innovative and intelligent features, which through motion, enhance the user experience across many Apple products. We are a high-energy team that has successfully delivered a wide spread of industry-leading software features including sensor fusion (e.g. device attitude and heading), motion gestures (e.g. raise wrist to light up Apple Watch), fitness tracking (e.g. steps and calories), and many more. As a member of our dynamic group, you will have the rare and rewarding opportunity to craft upcoming products that will delight and inspire millions of Apple's customers every single day.

Description
You will own the quality of CoreMotion features end to end, from user studies and data collection through algorithm validation and implementation testing, to driving the issues you find back into the design.

Responsibilities
Design and execute verification and validation strategies for motion algorithms: challenge the design and its implementation, define measurable pass/fail criteria, and build the test cases that expose where the algorithm breaks
Plan and run user studies and structured data collections, including protocol design, ground truth methodology, device and sensor configuration, and the data quality checks that make a collection reusable
Build and own the pipelines and processes that curate collected sensor data, from ingestion through to its use in algorithm design and validation
Develop test automation, tooling, and frameworks that execute motion tests continuously across devices and OS builds, and triage the failures they surface
Report and drive bugs to resolution, and communicate test coverage, quality status, and risk to all relevant stakeholders to drive the end to end user experience

Minimum qualifications
B.S. in Computer Science, Electrical Engineering, or equivalent experience
Proficiency in one or more programming/scripting languages or AI coding tools
Working knowledge of systems quality methodologies and test design practices
Demonstrated problem solving and debugging skills across hardware and software boundaries
Ability to work independently and drive tasks to completion with minimal direction
Strong written and verbal communication skills for cross-functional collaboration

Preferred qualifications
Experience testing sensor-based or embedded systems (IMU, sensor fusion, motion algorithms)
Experience building data curation or analysis pipelines, labeled datasets, and performance characterization tooling
Experience designing user studies or structured data collection protocols
Familiarity with test automation frameworks and continuous integration at scale
Attention to fine-grained detail in customer-facing quality
