Signal Integrity/Power Integrity Intern

About the Company

Etched is building hardware for frontier intelligence. We co-design chips, racks, software, and manufacturing to deliver best-in-class throughput and latency across both prefill and decode workloads. Our first products are heavily focused on inference.

Responsibilities

• Perform channel analysis for high-speed interfaces including PCIe, Ethernet, and other 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 measurements and lab data
• Partner with PCB layout, package, hardware, and ASIC teams to improve signal integrity
• Identify root causes of channel degradation and propose design improvements

Requirements

• 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

Preferred Qualifications

• Experience with Ansys HFSS, SIwave, ADS, CST, or similar simulation tools
• Experience with PCIe, Ethernet, DDR, or other high-speed interfaces
• Familiarity with Allegro, APD, ODB++, IPC2581, or other ECAD databases
• Experience processing Touchstone files and channel metrics
• Python scripting for simulation automation and data analysis
• Experience with laboratory measurements using VNAs, oscilloscopes, or TDR equipment

Benefits

• 12-week paid internship
• Generous housing support for those relocating
• Daily lunch and dinner in our office
• Direct mentorship from industry leaders and world-class engineers
