You will define, design, and verify ASIC packaging to be deployed in a range of Cisco platforms. Responsibilities: 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. Minimum Qualifications: Bachelors + 2 years of related experience, or Masters + 0 years of related experience. Experience with high-speed design principles, including Transmission Line Theory, electromagnetics, scattering parameters, and impedance network analysis. Experience in pre- and post-layout signal and power integrity (SI/PI) analysis. Experience with simulation using industry-standard EDA tools (e.g., Cadence Sigrity, Ansys HFSS, Keysight ADS). Experience planning and executing comprehensive SI/PI measurements and laboratory characterization. Preferred Qualifications: Experience with 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). Why Cisco?
