About the Job

Requirements

  • A bachelor's degree and at least two years of related experience, or a master's degree and no prior related experience.
  • 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 (BER) prediction.
  • Experience with pre- and post-layout signal and power integrity (SI/PI) analysis, including simulation using industry-standard electronic design automation tools such as Cadence Sigrity, Ansys HFSS, or Keysight ADS, and/or physical validation through detailed layout reviews and design validation using tools such as Cadence APD and Ansys electromagnetic flows, as well as laboratory measurements using a vector network analyzer (VNA), time-domain reflectometry (TDR), and other relevant instruments to validate simulation-to-measurement correlations.
  • Experience planning and executing comprehensive SI/PI measurements and laboratory characterization, including VNA measurements, TDR, impedance profiling, insertion and return loss analysis, and full channel characterization.
  • Experience performing SI/PI characterization, validation, and debugging of high-speed systems and packages using advanced equipment such as high-bandwidth oscilloscopes, spectrum analyzers, network analyzers, and probe stations.

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 and power integrity, provide feedback, and collaborate with the layout team to develop optimal solutions across interposer, substrate, and printed circuit board (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 resolve complex technical issues using advanced technology design rules.

Desired Qualifications

  • Experience articulating ideas and technical concepts to diverse audiences, both verbally and in writing.
  • Experience with high-bandwidth memory (HBM) or high-speed memory interface signal integrity.
  • Experience with die-to-die interfaces such as UCIe or proprietary interfaces.
  • Experience with advanced packaging, including CoWoS, EMIB, and interposer-based designs, and SI/PI analysis of 2.5D ASIC packaging.
  • Experience developing and executing test plans for high-speed interfaces, correlating measurement results with simulations, and driving root-cause analysis of SI/PI issues.
  • Experience analyzing and interpreting S-parameters, channel characteristics, crosstalk, reflections, impedance discontinuities, and power delivery network performance.
  • Experience collaborating with ASIC, 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.
