About the role

  • Perform signal integrity (SI) simulations using tools such as HyperLynx, HFSS, or CST.
  • Identify and resolve issues related to crosstalk, signal loss, reflections, and other performance degradations in high-speed designs.
  • Analyze PCB layout designs to ensure optimal signal performance, providing feedback and recommendations to layout and hardware design teams.
  • Collaborate with hardware engineers to optimize high-speed signal paths, ensuring adherence to specifications for interfaces like DDR5, PCIe, USB4, SerDes, and Ethernet.
  • Evaluate and validate signal integrity for power delivery networks (PDN) to minimize noise, ground bounce, and power/ground integrity issues.
  • Work closely with PCB layout, hardware, and mechanical teams to ensure design choices align with signal integrity best practices.
  • Develop and implement test strategies for verifying signal integrity on prototypes and final products using tools like oscilloscopes, vector network analyzers (VNA), and time domain reflectometry (TDR).
  • Create and maintain signal integrity design guidelines, best practices, and checklists to support hardware engineers throughout the product development lifecycle.
  • Diagnose and resolve SI issues during the bring-up phase of new products, ensuring minimal impact on time-to-market.

Requirements

  • Bachelor's or Master's degree in Electrical Engineering, Electronics Engineering, or a related field.
  • 5+ years of experience in signal integrity and related areas in hardware engineering with hands-on experience on LPDDR5, PCIe, USB4, SerDes and Ethernet protocols.
  • Strong understanding of high-speed signal transmission principles, including impedance, crosstalk, noise, and signal attenuation.
  • Proficiency in SI analysis tools such as Ansys HFSS, SIWave, CST or similar industry-standard software.
  • Hands-on experience with lab equipment such as oscilloscopes, VNAs, TDRs, and protocol analyzers.
  • Ability to contribute to process improvements and the development of new methodologies for signal integrity analysis.
Benefits
  • GM offers a workplace that genuinely fosters inclusion and belonging.
  • Non-Discrimination and Equal Employment Opportunities (U.S.)
