The Manufacturing Engineer, Supply Chain is a senior individual-contributor role that serves as the technical bridge between True's manufacturing operations and its supply base. Reporting to the Production Engineering Manager, this engineer owns make-vs-buy strategy, supplier development and qualification, component and material regulatory compliance, and procurement/sourcing engineering for the parts and materials consumed in True products. For approximately the first five years the role primarily supports the Monterrey (TMM) factory production expansions, with limited support to TMC on shared commodities. The role requires knowledge of what True manufactures and how — including where the business specializes internally and where it relies on external partners — combined with strong supply chain, procurement, and regulatory expertise. It partners daily across Manufacturing Engineering, R&D, Purchasing, Production Control, and Quality.
