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. What You'll Do: 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.
• GM DOES NOT PROVIDE IMMIGRATION-RELATED SPONSORSHIP FOR THIS ROLE. PLEASE DO NOT APPLY FOR THIS ROLE IF YOU WILL NEED GM IMMIGRATION SPONSORSHIP (e.g., H-1B, TN, STEM OPT, etc.) NOW OR IN THE FUTURE.
