Mixed Signal Engineer

Apple•Sunnyvale, CA

About The Position

Apple is seeking a self-motivated, passionate electrical engineer to work as an AMS Design Engineer on transistor-level IC design implementation for Apple Silicon across different technology nodes. The team develops custom analog designs used to connect Apple products to the physical world and optimize their performance. The role is part of a hands-on development team focused on engineering excellence, creativity, innovation, and cross-team collaboration. The engineer will conduct feasibility studies for analog and mixed-signal circuit blocks; design, document, and verify blocks; drive mask design and layout reviews; and run post-layout and top-level simulations to verify integration. The position also involves defining production and bench-level test plans, taking lab measurements to validate performance against specifications, and reviewing yield and lab test results to resolve bugs.

Requirements

Bachelor’s degree and a minimum of 3 years of relevant industry experience.
Strong device physics knowledge as it applies to analog IC design.
A track record of delivering silicon IPs with complete architecture, design, verification, and validation experience.
Solid understanding or experience in bandgaps, bias circuits, op amps, switched-capacitor circuits, LDOs, low-power oscillators, PLLs, VGAs, and feedback and compensation techniques.
In-depth knowledge and analytical understanding of mixed-signal design techniques.
Experience with top-level verification methods incorporating block-level schematics and behavioral models.
Experience with C, MATLAB, Verilog-A, or Python modeling.
Hands-on experience using spectrum analyzers, oscilloscopes, and signal generators to validate analog designs.
Good knowledge of high-precision techniques in the presence of device mismatch.
Understanding of data-converter architectures and design trade-offs.
Experience working with production test engineers on test plans and design-for-testability details.

Responsibilities

Conduct transistor-level feasibility studies for analog and mixed-signal circuit blocks.
Design circuit blocks and document design simulations and verification for formal design reviews.
Drive mask design to implement layout views and lead layout reviews.
Run post-layout and top-level simulations to verify top-level integration.
Define production and bench-level test plans.
Take lab measurements to validate performance compliance with specifications.
Drive and review yield and lab test results to address bugs.
Work with production test engineers to produce test plans and design-for-testability details.
