Job description

Software Integrity Engineer, CoreMotion, Sensing & Connectivity

Cupertino, California, United States Software and Services

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
