General Motors is a leading automotive company focused on innovation and sustainability. The Senior Signal Integrity Engineer plays a crucial role in ensuring the performance and reliability of high-speed hardware designs, involving simulations, measurements, and collaboration with cross-functional teams to support next-generation automotive systems.
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
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
