Signal Integrity Principal Engineer

Our Electrical Engineering team puts the spark into the full hardware development lifecycle, from concept to production. It takes experts in system architecture definition, design, analysis, prototyping, sourcing & the debugging and validation of layouts or routes to deliver state-of-the-art products for a changing world. We work closely with designers, cross-functional teams within Dell Technologies and suppliers to make sure electronic designs meet a range of requirements, including schedule, feature set, functionality and quality, as well as industry standards. 

Join us to do the best work of your career and make a profound social impact as a Signal Integrity Principal Engineer on our Core Hardware Development Team in Round Rock, Texas. 

What you’ll achieve 

As a Signal Integrity Principal Engineer, you’ll drive innovation across Dell’s enterprise hardware portfolio, i.e. Power Edge Servers, AI Servers, storage products. You’ll solve complex transmission-line challenges, guide best practices, and collaborate with internal teams and Original Design Manufacturer (ODM) partners to push what’s possible in high frequency designs. 

You will: 

• Build, validate, and correlate advanced Signal Integrity (SI) simulation models; Develop simulation strategies to characterize worst-case conditions across manufacturing and environmental variations 

• Analyze electrical designs and define routing/material/interconnect solutions for new highspeed interfaces such as PCIe, DDR, xGMI, UPI, etc… 

• Perform channel simulations across packages and PCBs 

• Work with IBIS-AMI, S-parameter models, and tools like Ansys HFSS, Keysight ADS, Cadence Allegro, and other leading industry tools 

• Optimize interconnects to meet insertion loss, return loss, eye diagram, and BER targets 

• Lead SI design reviews and influence platform wide best practices 

• Own electrical validation test plan development and support issue resolution 

• Collaborate with key technology suppliers on future-facing guidelines, tools, and ecosystem challenges 

Essential Requirements 

• 8+ years of experience in signal integrity role or equivalent skill; must have experience with server design and experience with both Peripheral Component Interconnect Express (PCIe) and Double Data Rate (DDR) interfaces 

• Strong fundamentals in transmission lines, electromagnetic (EM) fields, and analog/digital theory 

• Proficiency with SI simulation tools e.g. High-Frequency Structure Simulator (HFSS), SiWave, Advanced Design System (ADS); hands-on experience with Time Domain Reflectometry (TDR), Vector Network Analyzer (VNA), and other SI test equipment 

• Ability to perform Printed Circuit Board (PCB) layout reviews using Allegro, Xpedition, or similar 

• Proven collaboration with customers and crossfunctional teams 

 
Desirable Requirements 

• Bachelor's degree in either electrical engineering or computer engineering
