Printed circuit board design engineer

Job Summary:We are looking for an experienced PCB Design Engineer with strong expertise in high-speed digital design and signal integrity. This role involves owning the end-to-end design and validation of complex PCBAs featuring DDR memory and Ethernet interfaces, from architecture and simulation through layout guidance and lab validation.
Key Responsibilities:
Own complete PCBA design involving DDR memory and Ethernet switches/PHYs
Define PCB stack-up, controlled impedance requirements, and layout guidelines
Perform high-speed signal integrity simulations using tools such as Ansys SIwave or equivalent
Work with vendors to obtain and configure IBIS/AMI models
Guide or perform PCB layout, including floorplanning and routing constraints
Conduct board-level validation, including:
Eye diagram measurements
Bit Error Rate (BER) testing
Protocol compliance validation
Debug and optimize high-speed interfaces (DDR, Ethernet SGMII, etc.)
Configure device-level...
