Job Description
Senior Signal Integrity Engineer ensuring performance and reliability of high-speed hardware designs at General Motors. Collaborating with teams and optimizing design processes for 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.
Benefits:
- From day one, we're looking out for your well-being–at work and at home–so you can focus on realizing your ambitions.
