The Mixed-Signal IC Design Engineer will participate in defining, designing, developing, and bringing to production analog and mixed-signal circuits and sub-systems within Apple integrated circuit devices. This involves specifying, designing, implementing, and verifying these circuits, including transistor-level analog circuits, mixed-signal interfaces, and digital control and signal processing blocks. The engineer will also develop and run high-level simulations to validate top-level integration, collaborate with various cross-functional teams, define test plans, analyze results, create integration guides, and assist in the successful implementation of new circuits and sub-systems into complex SoCs. The role requires a strong understanding of analog and mixed-signal design principles and a proven track record of bringing circuits to production.
