Position Description:

As a Signal Integrity Expert, you will take a critical role in developing next generation data center Switches. You will be responsible for building SI/PI simulation process, validating results in lab for correlation to improve SI/PI design quality and provide the support to customers.

Specific Job Responsibilities:

• Main customer contact window for SI/PI design for data center Switches.
• Working with System design teams to evaluate design trade-offs and optimize design performance / risk / cost / manufacturability.
• Study of new technology, such as PCB material, Cable, Via technology etc.
• PCB material choosing and stack-up definition
• 3D passive channel modeling, perform SerDes channel extraction using electromagnetic tools
• Perform signal integrity pre-layout and post-layout analysis in R&D phase.
• Perform static timing and signal integrity analysis of parallel (common clock, source-synchronous) interfaces
• Design and analysis of multi-gigabit serial links, including lab verification and tuning.
• Perform power integrity analysis on power delivery network
• Generate and verify PCB layout rules, manage constraints for PCB layout
• Performing physical measurements to collect data for design validation and simulation correlations
• Be familiar with SAS, PCIe, DDR4, 25G/56G/112G Ethernet specification is a plus.

Qualifications:

• Experience with at least one PCB post-route SI tool: Cadence SPECCTRAQuest, Mentor ICX, SiSoft SI-Auditor (preferred), Sigrity Power SI.
• Experience with Synopsys HSPICE and/or Keysight ADS for both time and frequency domain circuit simulation.
• Experience with at least one 3-D field solver (CST Microwave Studio, ANSYS HFSS).
• Strong lab skills and measurement experience are required (VNA, TDR, Real Time Scope, BERT).
• Proficiency in Electromagnetic, Transmission-line & S-parameters theory and modeling.
• Good understanding on power distribution and SerDes(NRZ,PAM4) design.
• BSEE or related field with 8 years of applicable work experience or MSEE or related field with 5 years of experience.

Desired Skills:

• Experience of script languages like VB, Perl or Python
• Use of mathematic tools like Matlab
• Strong written and oral communication in English with customer service skills
