SI/PI Intern

About the role#

As an SI/PI Intern at Etched, you will contribute to the design and validation of high-performance AI systems. Working within the architecture department, you will collaborate with package, PCB, ASIC, and system engineering teams to analyze high-speed interfaces and optimize signal quality across accelerator platforms. This role involves hands-on work with industry-standard simulation tools and real-world challenges in high-speed digital design.

What you'll do#

• Perform channel analysis for high-speed interfaces, including PCIe, Ethernet, and various SerDes links.
• Extract and validate S-parameter models from package and PCB layouts.
• Analyze insertion loss, return loss, impedance discontinuities, and crosstalk.
• Build and validate 3D electromagnetic models using Ansys HFSS.
• Correlate simulation results with physical measurements and lab data.
• Partner with cross-functional teams to identify root causes of channel degradation and propose design improvements.
• Generate channel compliance reports and support design reviews.
• Develop automated workflows for simulation and data analysis.

What you'll need#

• Progress toward a BS, MS, or PhD in Electrical Engineering, Computer Engineering, or a related field.
• Coursework or project experience in signal integrity, electromagnetics, RF, microwave engineering, or high-speed digital design.
• Familiarity with transmission line theory and S-parameters.
• Understanding of PCB stackups, routing, and high-speed design fundamentals.
• Strong analytical and debugging skills.
• Experience with simulation tools such as Ansys HFSS, SIwave, ADS, or CST is preferred.
• Familiarity with ECAD databases like Allegro or APD is a plus.
• Proficiency in Python scripting for automation and experience with laboratory equipment like VNAs, oscilloscopes, or TDR is beneficial.
