Job description

Imagine what you can do here. Apple is a place where extraordinary people gather to do their lives best work. Together we create products and experiences people once couldn't have imagined, and now, can't imagine living without. It's the diversity of those people and their ideas that inspires the innovation that runs through everything we do.

Description

APPLE INC has the following available in San Diego, California. Design BMU from concept to mass production focusing on detailed board level design. Push the boundaries of technologies to maximize performance and minimize volume. Collaborate with multi-functional partners (Product Design, System EE, Cell Engineering, Firmware, Algorithms, etc.) to ensure the product is developed on time and on budget. Conduct investigations and prepare reports for problems or issues. Develop Schematics and BOMs to satisfy the design requirements. Develop layout guidelines for PCBs and guides Layout Engineers to meet all physical and electrical requirements of BMU. Specify custom parts and PCBs for use in BMUs. Analyze the design with simulation tools and calculations to verify its conformance to the requirements. (PSPICE, ANSYS, Verilog or equivalent). Conduct design validation on prototypes to implement the design. Conduct design reviews, incorporate team feedback and release the design documents for builds. Specify production test methods and limits and work with CM partners to realize design. 40 hours/week. 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 $163,197 - $207,100/yr and your base pay will depend on your skills, qualifications, experience, and location.
