Mixed-Signal Design Engineer

Apple•Austin, TX

About The Position

We are seeking talented High Speed Analog/RF/Mixed-Signal designers to join our analog circuit design team! Our team specializes in building cutting edge analog and mixed signal IPs that support the future roadmap of exciting Apple products, including Apple’s world-leading system-on-chip (SOC). In this role, you will actively work with cross-functional Analog Mixed-Signal design teams to create and execute on state-of-the-art IPs key to Apple’s products. You will be challenged to make best-in-class designs to surprise and delight Apple customers. With redefining the user experience in focus, you will get an opportunity to work on designs which makes the best systems. This enables you to learn end-to-end system while exceeding the highest expectations of quality, innovation and efficiency. If you have strong fundamentals and a track record of tackling technical challenges, you are passionate about learning new skills and improving the value of your work, and you like to be tuned to the bigger-picture while diving deeply into the details to innovate and tackle problems- we invite you to join and grow with our team! You will have the opportunity to work on the development of high-performance and high-speed AMS circuits used in wide range of Apple SoCs, ranging from highspeed links to reference, oscillators and other clocking circuits, data converters, signal conditioning ckts, sensors, etc, including evaluation of different circuit topologies for specific product requirements (e.g.,design for low noise, robust power supply rejection, and excellent phase noise that can survive challenging mixed signal environments, while also implementing mixed signal control loops to optimize product performance). We are challenged to do this while maintaining best in class power, performance, and area (PPA). You will work with cross-functional teams (e.g., architecture, SIPI, packaging, board design, DFT, ESD) to create block-level specifications and execute on transistor-level implementation and behavioral modeling. You will drive mask design to implement layout view of designs. You will closely work with SOC teams to deliver IP views and make sure they meet the quality standards. While developing these complex IPs, on regular basis you will interact with your peers/management to communicate progress and discuss new ideas making it a lively and interactive work environment.

Requirements

BS and a minimum of 10 years relevant industry experience.
