About the Job

Requirements

  • A Bachelor's degree plus 2 years of related experience, or a Master's degree plus 0 years of related experience is required.
  • Experience with high-speed design principles, including transmission line theory, electromagnetics, scattering parameters, and impedance network analysis, applied to 56G PAM4 SerDes architectures, channel modeling, and bit error rate prediction is required.
  • Experience in pre- and post-layout signal and power integrity analysis is required, including simulation using industry-standard electronic design automation tools such as Cadence Sigrity, Ansys HFSS, and Keysight ADS, and/or physical validation through detailed layout reviews, design validation using Cadence APD and Ansys electromagnetic flows, and lab measurements using vector network analyzers, time-domain reflectometers, and other relevant instruments.
  • Experience planning and executing signal and power integrity measurements and laboratory characterization, including vector network analyzer measurements, time-domain reflectometry, impedance profiling, insertion- and return-loss analysis, and full channel characterization is required.
  • Experience performing signal and power integrity characterization, validation, and debugging of high-speed systems and packages using high-bandwidth oscilloscopes, spectrum analyzers, network analyzers, and probe stations is required.

Responsibilities

  • Develop, document, and implement design rules for ultra-high-speed signaling to ensure products meet power, performance, and area goals.
  • Analyze substrate signal integrity and power integrity, and provide feedback while collaborating with the layout team to develop optimal solutions across interposers, substrates, and printed circuit boards.
  • Design, document, and develop application-specific integrated circuit 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 resolve complex technical issues using advanced technology design rules.

Desired Qualifications

  • Experience with articulating ideas and technical concepts to diverse audiences, both verbally and in writing.
  • Experience with high-bandwidth memory or high-speed memory interface signal integrity.
  • Experience with die-to-die interfaces such as UCIe or proprietary interfaces.
  • Experience with advanced packaging such as CoWoS, EMIB, and interposer-based designs, including signal and power integrity analysis of 2.5D application-specific integrated circuit packaging.
  • Experience developing and executing test plans for high-speed interfaces, correlating measurement results with simulations, and driving root-cause analysis of signal and power integrity issues.
  • Experience analyzing and interpreting S-parameters, channel characteristics, crosstalk, reflections, impedance discontinuities, and power delivery network performance.
  • Experience collaborating with application-specific integrated circuit, package, board design, and system engineering teams to optimize end-to-end signal and power integrity.

About the Company

Cisco

Makes networking gear and security software

Cisco makes the switches and routers that connect offices, data centers, and cloud services, and it also sells cybersecurity tools and Webex video meetings to businesses and governments. It was one of the first companies to sell routers that let different kinds of computer networks exchange data, and in 2000 it briefly became the world's most valuable company. Customers run its network gear, from Wi-Fi access points to AI data center systems, with Cisco software that sets up and secures the network, while its Splunk unit searches computer logs to catch outages and attacks. Cisco earns money from hardware sales, software subscriptions, and support contracts. It was founded in 1984 and is based in San Jose, California.
