Senior Signal Integrity & Power Integrity Engineer

Drive advanced signal and power integrity initiatives for next-generation high-speed digital interfaces by leveraging deep simulation expertise and in-depth PCB design knowledge. This role is responsible for ensuring robust performance of interfaces up to 448Gbps through comprehensive electromagnetic modeling, analysis, and the development of practical design guidelines.

Responsibilities

• Perform high-frequency electromagnetic simulations for high-speed interfaces (224Gbps, 448Gbps) using Ansys HFSS and Keysight ADS.
• Execute comprehensive power delivery network (PDN) analysis using industry-standard simulation tools.
• Analyze signal integrity for advanced interfaces such as PAM4 (56Gbps, 112Gbps) and NRZ (minimum 25Gbps), focusing on simulation-based validation and correlation with measurement data, including eye diagram analysis, jitter/noise analysis, and S-parameter correlation.
• Apply and document impedance control, transmission line, and PCB manufacturing best practices in practical design guidelines.
• Prepare thorough technical documentation of simulation methods, results, and recommendations to support hardware development processes.
• Demonstrate familiarity with Ethernet high-speed interface standards (25G/100G/400G/800G) in simulation and analysis workflows.
• Collaborate with PCB layout engineers to review and optimize board designs for signal and power integrity in server, data center, and network infrastructure hardware.

Minimum Qualifications

• 5+ years of hands-on experience in signal integrity simulation for high-speed digital systems.
• Proficiency with simulation tools such as Ansys HFSS, Cadence Sigrity, PowerSI, Ansys SIwave, and Keysight ADS.
• Direct experience with high-speed interface technologies, specifically with PAM4 (56Gbps, 112Gbps) and minimum 25Gbps NRZ links.
• Extensive knowledge of signal and power integrity concepts, PCB stack-up optimization, impedance control, and fabrication constraints.
• Strong organizational skills and exceptional technical documentation abilities.

Preferred Qualifications

• Master’s degree in Electrical Engineering, Physics, Mathematics, or a related discipline, or equivalent industrial experience.
• 8+ years of experience in comprehensive signal and power integrity evaluation for high-performance electronic systems.
• Advanced expertise in the development of design guidelines for ultra-high-speed interconnects.
• Experience collaborating with PCB fabrication vendors to implement and verify complex impedance-controlled layouts.
