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. Our team doesn't just build products, we deliver inspiring technology and information to users on the most critical area of their lives - their health. Dynamic, inquisitive 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 highly multi-functional environment and mainly supply 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. Key Qualifications Hands-on experience and consistent track record in electrical sensing system hardware engineering. Strong background on multiple of these areas: sensor interface circuit/system architecture, analog/mixed signal design, simulation/modeling, electrical sensing modalities (voltage, current, impedance) or data processing and analysis. Proficiency in system engineering, hardware architecture, ASIC definition and/or design. Proficiency in Python, Matlab, SPICE or similar simulation tools. Experience in machine learning or firmware development is a plus. Experience in prototype for physiological sensor signal acquisition and design & complete user study is a plus. Excellent written and verbal communication skills, as well as solid teamwork. Description 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 develop sensing hardware and responsible for following: Conduct architecture design, simulation, modeling, board level circuit and system design for health sensing products in the entire lifecycle of a new product, from initial design and functional specification of new hardware features and overall architecture design all the way 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 scalable solution to support Apple mass production in a high quality way - Collaborate closely with multi-functional partners (FW, Algorithm), including problem solving and requirement drafting across various functions and disciplines Education & Experience BS and a minimum of 10 years relevant industry experience Pay & Benefits At Apple, base pay is one part of our total compensation package and is determined within a range. This provides the opportunity to progress as you grow and develop within a role. The base pay range for this role is between $170,700.00 and $300,200.00, and your base pay will depend on your skills, qualifications, experience, and location. Apple employees also have the opportunity to become an Apple shareholder through participation in Apple's discretionary employee stock programs. Apple employees are eligible for discretionary restricted stock unit awards, and can purchase Apple stock at a discount if voluntarily participating in Apple's Employee Stock Purchase Plan. You'll also receive benefits including: Comprehensive medical and dental coverage, retirement benefits, a range of discounted products and free services, and for formal education related to advancing your career at Apple, reimbursement for certain educational expenses - including tuition. Additionally, this role might be eligible for discretionary bonuses or commission payments as well as relocation.
