Signal Integrity Engineer - DDR4 / DDR5

Job Description

Johns Creek, GA or San Jose, CA

About the Role

We are a leading provider of chip and silicon IP solutions, seeking an exceptional Senior  Engineer with signal integrity and package design expertise to join our Memory Interface engineering team. This full-time role involves developing products that boost data speed and security. Reporting to the VP of Engineering, you'll focus on SI / PI modeling, analysis, and simulations for high-speed DDR applications up to 12800+ MT / s.

Key Responsibilities

• Develop SI / PI methodologies; collaborate on studies and package designs for DDR products.
• Define specs and requirements (e.g., packaging, PCB routings, decoupling, simulations, jitter analysis) with design / validation teams.
• Guide design team via SI / PI studies, simulations, and correlations for top SI performance (e.g., optimal RMT scores).
• Partner with customers on optimal SI / PI solutions.
• Support debug and lab bring-up.
