You will be responsible for the specification, design, validation and deployment of automated equipment to test and calibrate devices for Apple’s new product introduction (NPI) and mass production. Responsibilities will be tuned to match the candidate’s technical background, but you may be encouraged to: - Architect hardware for systems to test and calibrate optical and health sensors. - Model, simulate and experimentally verify sources of instrumentation error, and determine measurement uncertainty as it relates to the overall needs for the product. - Develop, optimize, and debug test software in C/C++/Objective-C - Collaborate with cross functional teams to specify and implement test coverage - Analyze large amounts of sensor data and use data driven approaches to tackle engineering challenges - Perform failure mode root cause analysis and resolution, debugging from the system level down to the component level - Redefine existing algorithms to optimize them for performance or execution time - Balance decisions between engineering asks and manufacturing efficiency while ensuring product quality - Lead cross-functional teams and mentor junior engineers on the team - Work collaboratively with a creative and diverse team of expert engineers from all disciplines including Systems Hardware, Product Design, Reliability, Software and Operations
