Shilpan Amin sits at the operational core of General Motors. As the global chief procurement and supply chain officer, his remit cuts across engineering, manufacturing, finance, and the company's vast supplier network. At GM's scale, procurement is not simply about buying parts. It determines how capital is deployed, how risk is priced and absorbed, how quickly vehicles move from design to launch, and how the company navigates geopolitical shocks while protecting long-term margins.
