About the role

Key responsibilities & impact

Perform signal integrity (SI) simulations using tools such as HyperLynx, HFSS, or CST
Identify and resolve issues related to crosstalk, signal loss, reflections, and other performance degradations in high-speed designs.
Analyze PCB layout designs to ensure optimal signal performance, providing feedback and recommendations to layout and hardware design teams.
Collaborate with hardware engineers to optimize high-speed signal paths, ensuring adherence to specifications for interfaces like DDR5, PCIe, USB4, SerDes, and Ethernet.
Evaluate and validate signal integrity for power delivery networks (PDN) to minimize noise, ground bounce, and power/ground integrity issues.
Work closely with PCB layout, hardware, and mechanical teams to ensure design choices align with signal integrity best practices.
Develop and implement test strategies for verifying signal integrity on prototypes and final products using tools like oscilloscopes, vector network analyzers (VNA), and time domain reflectometry (TDR).
Create and maintain signal integrity design guidelines, best practices, and checklists to support hardware engineers throughout the product development lifecycle.
Diagnose and resolve SI issues during the bring-up phase of new products, ensuring minimal impact on time-to-market.

Requirements

What you’ll need
