About the position

The Senior Signal Integrity Engineer at General Motors plays a crucial role in ensuring the performance and reliability of high-speed hardware designs. This position involves analyzing and mitigating signal degradation issues in next-generation Electronic Control Units (ECUs) and collaborating with cross-functional teams to optimize design processes. The engineer will support the semiconductor strategy and drive innovation in the automotive industry, focusing on in-vehicle electronics and cutting-edge technologies.

Responsibilities

• Perform detailed signal integrity (SI) simulations using tools such as HyperLynx, HFSS, or CST to 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 DDR, PCIe, USB, 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.
• Partner with systems engineering and software teams to ensure signal integrity across the entire product stack, from silicon to system integration.
• 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.
• Lead the evaluation of new materials, design techniques, and tools.

Requirements

• Experience in signal integrity analysis and simulation for high-speed designs.
• Proficiency with engineering tools such as HyperLynx, HFSS, or CST.
• Strong understanding of PCB layout design and optimization for signal integrity.
• Experience with high-speed interfaces like DDR, PCIe, USB, SerDes, and Ethernet.
• Ability to collaborate effectively with cross-functional teams including hardware, systems engineering, and software.

Nice-to-haves

• Experience with power delivery network (PDN) analysis and validation.
• Familiarity with test equipment such as oscilloscopes, vector network analyzers (VNA), and time domain reflectometry (TDR).
• Knowledge of emerging technologies in automotive electronics.
