Staff Systems Engineer- Network Performance Analyst

Description The Role:

We are seeking a highly skilled and motivated Network Performance Analyst to lead the definition, assessment, and continuous improvement of in-vehicle network performance across multiple vehicle product spaces. This role is critical in establishing and managing the Network Performance Budget, Forecast, and Load Assessment for GM's electrical architecture, ensuring that current and future feature content can be delivered reliably and at scale across Ethernet, CAN, LIN, and other in-vehicle networks. The ideal candidate will bring deep expertise in automotive network architectures and performance analysis, strong systems thinking, and a collaborative mindset to drive data-driven decisions and architectural trade-offs. This role partners closely with Electrical Architecture PSEs, ECU software and hardware teams, and product/program leadership to ensure that network capacity and performance are designed, measured, and governed as a first-class architectural concern. What You'll Do (Responsibilities): Network Performance Budget & Forecast Define and maintain the Network Performance Budget by product area (e.g., propulsion, body, chassis, ADAS, infotainment) across vehicle programs and architectures. Forecast future network loading and bandwidth needs based on product roadmaps, feature growth, and architectural strategy (SDV2 & beyond). Network Load Assessment & Analysis Drive end-to-end network load assessment activities including message catalog reviews, traffic modeling, and simulation/measurement of bus utilization, latency, and jitter for Ethernet, CAN, LIN, and other vehicle networks. Establish clear criteria and thresholds for acceptable network loading and performance and communicate these to product teams. Network Performance Dashboarding Create and manage a Network Performance Dashboard that provides visibility to leadership and product teams on current and projected network performance health. Design Reviews & Governance Support Electrical Architecture Reviews (EAR) and other forums to evaluate the network implications of new features, ECUs, and topology changes, providing clear recommendations and risk assessments. Partner with EA PSEs to ensure adherence to Electrical Architecture Core Principles , including performance, reliability, and scalability, and provide data-driven input to NAR/SAR and other change control processes. Collaboration with Software, Hardware, and Microcontroller Stakeholders Act as a key interface between network performance analysis, ECU software teams, hardware design teams, and microcontroller strategy teams to align on bandwidth needs, timing budgets, and implementation constraints.
