Signal and Power Integrity Engineer

Overview

Lead the advancement of signal and power integrity solutions for state-of-the-art high-speed digital interfaces, driving robust interface performance through rigorous electromagnetic simulation and in-depth PCB design proficiency. This role is instrumental in developing practical design guidelines and ensuring the reliability of digital links operating up to 448Gbps within advanced hardware systems.

Responsibilities

• Conduct high-frequency electromagnetic simulations of next-generation interfaces (224Gbps, 448Gbps) utilizing tools such as Ansys HFSS and Keysight ADS.
• Execute detailed power delivery network (PDN) analysis with industry-standard simulation software.
• Analyze and validate signal integrity for advanced PAM4 (56Gbps, 112Gbps) and NRZ (≥25Gbps) digital interfaces, including comprehensive eye diagram, jitter/noise, and S-parameter correlation between simulation and measurement data.
• Develop, apply, and document best practices in impedance control, transmission line design, PCB stack-ups, and practical PCB manufacturing processes within actionable guidelines.
• Prepare precise technical documentation on simulation approaches, findings, and recommendations to inform and support the hardware development lifecycle.
• Integrate a working knowledge of Ethernet high-speed interface standards (25G/100G/400G/800G) into simulation and analysis tasks.
• Partner with PCB layout engineers to evaluate and optimize board layouts for signal and power integrity in server, data center, and network hardware platforms.
