About The Position

The Role: The Senior Signal Integrity Engineer at General Motors plays a crucial role in ensuring the performance and reliability of high-speed hardware designs within the ECU Electrical team. This position involves simulating HW designs, measurements in lab mitigating signal degradation issues, collaborating with cross-functional teams, and optimizing design processes to support the development of next-generation automotive systems. The engineer will be responsible for product development activities, focusing on in-vehicle electronics and cutting-edge technologies.

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 experie nce 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.

Responsibilities

• 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.
