Custom Circuits Design Engineer

Apple•San Diego, CA

About The Position

Do you have a passion for crafting entirely new solutions? Do you love building without precedent? As part of our Digital group, you’ll take imaginative and revolutionary ideas and determine how to turn them into reality. You and your team will apply engineering fundamentals and start from scratch if needed, bringing forward-thinking ideas to the real world. Your efforts will be groundbreaking, often literally. Join us, and you’ll help design the tools that allow us to bring customers experiences they’ve never before envisioned. You will be part of an exciting silicon design group that is responsible for designing state-of-the-art ASICs. We have an extraordinary opportunity for Circuits Engineers to design advanced custom digital megacells (SRAM memories, on-chip sensors, ML accelerators data path) used in a high performance / low power SOC. DESCRIPTION Imagine yourself at the center of our SOC design effort, collaborating with all fields, with a critical impact and playing a strategic role of getting functional products to millions of customers quickly. You will have the opportunity to integrate and come-up with new ideas, as well as work with a team of hardworking engineers. You will perform the following - - Develop custom circuits to improve chip power efficiency. - Work with power team, PD and architects to define specifications and requirements - Perform design, analysis, modeling/simulation, circuit level specifications, schematic capture, spice simulation / margin verification across PVT, statistical design, functional verification and silicon bring up. - Work closely with layout team to complete the design and oversee the layout quality. - Develop / drive circuit methodology to achieve the highest design quality metrics.

Requirements

BS and a minimum of 10 years of relevant industry experience
