System Signal & Power Integrity Hardware ASIC Simulation Engineer; Hybrid

Signal And Power Integrity Engineer

We are seeking a qualified Signal and Power Integrity Engineer to help us develop our next generation ASIC packaging to help define, design and verify ASIC packaging to be deployed in a range of Cisco platforms.

Cisco Silicon One is a business organization with a long track record of building complex and high-performance Silicon ASICs. Our silicon devices drive the world's most complex networks and carry over 90% of IP traffic. Cisco Silicon One is the only unifying silicon architecture in the market that enables customers to deploy the best-of-breed silicon from Top of Rack (TOR) switches all the way through web scale data centers and across service provider, enterprise networks, and data centers with a fully unified routing and switching portfolio.

We are a highly specialized ASIC team with experts in all aspects of advanced IC package design and heterogeneous system integration. Our substrates use the latest 2.5D fanout technologies for large-scale integration, using the latest signaling and data transfer technologies. Come join us and take part in shaping Cisco's ground-breaking solutions by designing, developing and testing some of the most complex ASICs being developed in the industry!

• Develop, document, and implement design rules for ultra-high-speed signaling, ensuring power, performance, and area goals are met for products.
• Analyze substrate signal integrity (SI) and power integrity (PI), providing feedback and collaborating with the layout team to develop optimal solutions across interposer, substrate, and PCB.
• Design, document, and develop ASIC packages for high-volume, high-quality release, including post-layout extraction and reporting.
• Collaborate with system partners, vendors, and design leads to achieve combined power and signal integrity and to resolve complex technical issues using advanced technology design rules.

• Bachelor's degree in Electrical Engineering and 4+ years of relevant signal and power integrity experience, or Master's degree in Electrical Engineering and 2+ years of relevant signal and power integrity experience, or PhD in Electrical Engineering and 0+ years of related experience, or equivalent related work experience.
• High-Speed Design & Theory:
  Expertise in high-speed design principles, including Transmission Line Theory, electromagnetics, scattering parameters, and impedance network analysis, applied to 56G PAM4 Ser Des architectures, channel modeling, and BER prediction.
• SI/PI Simulation Proficiency:
  Experience with pre- and post-layout signal and power integrity (SI/PI) simulations using industry-standard EDA tools such as Cadence Sigrity, Ansys HFSS, and Keysight ADS.
• Layout Review & Physical Validation:
  Experience conducting detailed layout reviews and physical design validation using tools such as Cadence APD and Ansys EM flows to ensure signal performance and crosstalk mitigation.
• Circuit Analysis:
  Working knowledge of SPICE for circuit-level analysis, signal modeling, and performance validation.

• Skilled in articulating ideas and technical concepts to diverse audiences, both verbally and in writing.
• Experience with high-bandwidth memory (HBM) or high-speed memory interface SI.
• Experience with die-to-die interfaces (UCIe or proprietary).
• Experience with advanced packaging (CoWoS, EMIB, interposer-based designs), including SI/PI analysis of 2.5D ASIC packaging.
• Working knowledge of Vector Network Analysis.
• Basic knowledge of IBIS.
