Vehicle Mass Systems & Tools Engineer

At General Motors, our product teams are redefining mobility. Through a human-centered design process, we create vehicles and experiences that are designed not just to be seen, but to be felt. We’re turning today’s impossible into tomorrow’s standard —from breakthrough hardware and battery systems to intuitive design, intelligent software, and next-generation safety and entertainment features. Every day, our products move millions of people as we aim to make driving safer, smarter, and more connected, shaping the future of transportation on a global scale.

Are you passionate about building the digital backbone that enables world-class vehicle mass engineering? The GMNA Vehicle Mass Integration team is seeking a highly motivated Technical Specialist to serve as the Global Owner for Mass Systems and Tools — the expert who designs, develops, and sustains the engineering infrastructure that the Technical Integration Engineer (TIE) and Vehicle Performance Owner (VPO) rely on every day. This role sits at the intersection of mass engineering, data systems, and emerging technology. You will be the go-to expert for the full portfolio of mass engineering tools — from critical enterprise systems like NGVMC and GPDS, to advanced modeling tools like THERA and the Mass Book Tool — while actively exploring how AI and automation can elevate the speed and accuracy of mass-related deliverables across the enterprise. You will work directly in support of the Mass TIE (Technical Integration Engineer) and Mass VPO (Vehicle Performance Owner), enabling their processes with reliable, efficient, and innovative digital solutions. Impact & Growth As the Technical Specialist for Vehicle Mass Systems & Tools, you will have enterprise-wide influence — levering your own mass knowledge and the mass team’s most critical technical leaders (TIE and VPO) to directly develop the systems and tools they need to succeed. You will be at the leading edge of how GM integrates AI and automation into vehicle engineering, shaping what the future of mass engineering looks like at scale. This role offers pathways toward Technical Fellow opportunities, broader GPEC systems leadership, or cross-functional IT/engineering integration roles. What You’ll Do (Responsibilities): Systems Ownership & Development Serve as the Global Process and Systems Owner for the full mass engineering toolchain, including NGVMC, GPDS, THERA, the Mass Book Tool, and supporting macros and data pipelines. Lead the creation, enhancement, and maintenance of digital tools and systems that support mass engineers globally throughout the GVDP (Global Vehicle Development Process). Define requirements, develop solutions, and partner with IT to deliver system improvements aligned with evolving mass engineering needs. Ensure data integrity, system reliability, and user accessibility across all mass-related platforms. Support of TIE and VPO Processes Partner directly with the Mass TIE (Technical Integration Engineer – AVD) and Mass VPO (Vehicle Performance Owner – Execution) and leverage own deep understanding of the mass role (from AVD to execution) to resolve process pain points and develop enabling tool solutions. Innovate, design, execute and validate tools that support Advanced Vehicle Development (AVD) mass target setting, regression modeling, and early-phase architecture decision-making. Execution-phase mass tracking, Model & Option Weight (MOW) management, certification mass workflows, and compliance reporting. Ensure the tools ecosystem seamlessly connects AVD and execution phases, enabling continuity of mass data and process from early program through production. Provide analytical support to the TIE and VPO for data-driven decision making. AI and Innovation Actively explore and evaluate emerging technologies — including artificial intelligence, machine learning, and data analytics — to elevate the efficiency and accuracy of mass-related
