Austin, Texas, United States


Posted: Oct 25, 2018
Role Number: 200001296
Imagine what you could do here. At Apple, new ideas have a way of becoming extraordinary products, services, and customer experiences very quickly. Bring passion and dedication to your job and there's no telling what you could accomplish. In this highly visible role as a senior member of our CAD team, you will architect, develop, maintain and improve simulation methodology and solutions for our Analog, RF and Mixed-signal designs. You will be working with different technology nodes and provide flows/methodologies for the different tool sets. You will also be collaborating with the analog, mixed-signal, and RF circuit design teams. Work will also involve partnering with layout design, technology, and 3rd party EDA tool vendors to drive and lead effort of developing and validating simulation flows, improving custom design environment, validating checks and doing results analysis. The people who work here have reinvented entire industries with all Apple Hardware products. The same passion for innovation that goes into our products also applies to our practices — strengthening our dedication to leave the world better than we found it. Join us to help deliver the next groundbreaking Apple products.
