Health Sensing - Electrical Technology HW Architect

Health Sensing - Electrical Technology HW Architect

Cupertino, California, United States Hardware

The Health Sensing team conceives, designs, develops, and launches innovative and exciting health sensing technologies for Apple’s future products, while expanding an impactful new domain for the company. The people on the team don’t just build products. They deliver inspiring technology and information to users on the most critical area of their lives - their health. Dynamic, smart people and inspiring, innovative technologies are the norm here, not to mention letters of how these features helped improve or save people’s lives.

Imagine what you could do here! You will work in a highly cross‑functional environment and mainly contribute on hardware architecture design for development for electrical sensing health features, such as ECG in the Apple Watch. The role’s responsibilities will encompass health‑sensing circuit and system design, simulation and modeling, data processing/analysis along with crafting well‑documented specifications and rationale.

We are responsible for designing and delivering high quality electrical health‑sensing features for Apple’s product. We are highly collaborative and partner with a variety of teams across Apple. You will mainly work on developing sensing hardware and be responsible for the following: conduct architecture design, simulation, modeling, board‑level circuit and system design for health‑sensing products throughout the entire lifecycle of a new product, from initial design and functional specification of new hardware features and overall architecture design through to support and validation of these features.

Review schematics, layout and other design collateral for fabrication. Develop analysis and modeling tools for hardware performance, perform complex system‑level tests, enhance and resolve issues in existing products, and perform unit testing and end‑to‑end testing. Collect and process environmental and physiological data from users to draw conclusions, predict performance of new designs and components based on simulation and modeling tools.

Translate feature requirements into electrical hardware specifications and validate performance against specifications. Drive the development of component and modules to meet pre‑defined specifications. Analyze and leverage manufacturing data to improve quality and minimize defects. Drive failure analysis to understand root‑cause and implement corrective actions. Author evaluation plans, technical documentation such as Engineering Requirements Specification (ERS), and aid in bring‑up to deliver a scalable solution to support Apple mass production in a high‑quality way.

Collaborate closely with cross‑functional partners (FW, Algorithm), including problem solving and requirement drafting across various functions and disciplines.
