Analog Mixed/Signal IC Designer

At Apple, we work every single day to craft products that enrich people’s lives. Do you love working on challenges that no one has solved yet? Do you like changing the game? We have an opportunity for a forward-thinking and especially talented Analog Mixed-Signal IC Designer. As a member of our dynamic group, you will have the rare and rewarding opportunity to craft upcoming products that will delight and inspire millions of Apple’s customers every day.Apple Silicon Engineering is seeking qualified circuit designers to work on the next generation analog & mixed-signal (AMS) circuits for Apple’s world-leading systems-on-chip (SOCs)! Apple’s Ax SOCs are the brain of every iPhone and iPad. Several types of AMS circuits are used to connect them to the physical world as well as enable optimizing their performance. You will be part of a growing AMS team involved in design and productization on leading-edge CMOS process technology nodes!

Key Qualifications
