Senior/Principal High-Speed Analog Layout Design Engineer

We are seeking a Principal/Senior Analog Layout Engineer to drive the layout design of complex analog and mixed-signal IP blocks that are at the heart of our advanced optical communication systems. As a key member of the Analog & Mixed-Signal (AMS) design team, you will lead layout development of critical blocks such as ADCs, DACs, PLLs, and other high-performance analog/mixed-signal circuits. You will interface closely with circuit designers, CAD/PDK teams, and other layout engineers to ensure first-pass silicon success. This is a hands-on technical role ideal for someone who thrives in a fast-paced environment and enjoys mentoring others while contributing directly to cutting-edge chip development.
