Cisco Systems, Inc.
Meet the Team
The Cisco Service Provider SI team is seeking a Signal Integrity Engineer for the design and analysis of high-speed components, interfaces, and power distribution network. As a member of the Service Provider SI team, you will help develop the Next Generations of Cisco Switch products, be a part of the definition and design of current and next generation ASIC, package, printed circuit board (PCB), and system interconnect. You will be working in a larger team working closely with system architects, logic designers, ASIC engineers, package engineers, and versatile and knowledgeable SI/PI engineers in the creation of next-generation networking products.
Your Impact
High-speed link modeling and
simulation, including high-speed I/O, IC package, and system
interconnections. Modeling and analyzing power
delivery networks. Electromagnetic modeling of
complex 3-dimensional structures. Perform pre- and post-route
signal integrity analysis of both PCB and ASIC package designs. Write signal integrity design
guidelines, test plan, and test report. Decide appropriate PCB material,
stack-up, and work with vendors to address any DFM issues. Support prototype function
bring-up, validation, and troubleshooting. Address signal integrity
challenges on system high-speed interconnections, clock, power, etc. Work closely with other hardware
function teams including HW design, eCAD, Mechanical, Power, EMC, and Diag
to deliver first-class products. Contribute to the overall SI/PI
technology roadmap, evaluating new tools, techniques, and design
approaches to maintain a competitive edge Minimum Qualifications 5+ years of related experience with a Bachelor's
Degree in BSEE, or 3+ years of experience with a Master's Degree,
relevant/transferable professional work, and/or classroom learning. BSEE degree. Experience applying EE fundamentals, EM
theory, and coupling mechanisms in circuit or system design, analysis, or
troubleshooting through projects, coursework, or work experience. Hands-on
experience with simulation or analysis of transmission lines, channel
modeling, and signal/power integrity via academic or professional
projects. Practical experience configuring and interpreting measurements from VNA, TDR, and oscilloscopes, demonstrated in lab, research, or engineering roles. Preferred Qualifications Strong tools knowledge with tools
such as HFSS, ADS, Matlab, Cadence PowerSI/DC, Allegro, Simbeor, and
HSpice. Proficiency with 3-D field
solvers and PI (Power Integrity) simulation tools such as PowerSI/DC. Self-motivation, collaboration,
strong communication, and a desire to innovate are important. Working experience with
high-speed NRZ and PAM4 SerDes, as well as high-speed PCB/package
development and PI analysis, is a plus. Masters or PhD in Electrical
Engineering Knowledge of optical transceiver
module types, form factors, and requirements. Why Cisco? At Cisco, we're revolutionizing how data and infrastructure connect and protect organizations in the AI era - and beyond. We've been innovating fearlessly for 40 years to create solutions that power how humans and technology work together across the physical and digital worlds. These solutions provide customers with unparalleled security, visibility, and insights across the entire digital footprint. Simply put - we power the future. Fueled by the depth and breadth of our technology, we experiment and create meaningful solutions. Add to that our worldwide network of doers and experts, and you'll see that the opportunities to grow and build are limitless. We work as a team, collaborating with empathy to make really big things happen on a global scale. Because our solutions are everywhere, our impact is everywhere. We are Cisco, and our power starts with you.
