About this role
Onsemi is seeking a senior manager to lead its backend semiconductor sourcing function from San Jose, overseeing a team responsible for assembly, test, packaging, substrates, and related manufacturing services. This role sits at the intersection of strategy and execution, requiring you to develop supplier and category strategies aligned with corporate and business-unit objectives while managing day-to-day relationships with OSATs, substrate providers, and test manufacturers across the United States, Asia, and Europe. You'll balance competing priorities—long-term capacity and technology roadmaps against near-term operational needs—and own negotiations for complex commercial agreements covering capacity, tooling, non-recurring engineering, and cost structures.
Success in this position demands deep semiconductor backend expertise and proven ability to influence across global, matrixed organizations. You should bring 10+ years in the industry with substantial experience in backend sourcing, assembly and test manufacturing, or supply chain operations, plus a track record of leading teams through complex projects and delivering measurable cost, quality, and supply-risk improvements. The role requires fluency in semiconductor economics, packaging and test technologies, and supplier cost drivers, along with strong commercial negotiation skills and the ability to translate product and technology requirements into actionable sourcing strategies.
This is an in-office, full-time position requiring regular global travel and the ability to work from the San Jose location. A bachelor's degree in engineering, supply chain, business, finance, or a related field is required; an advanced degree and established relationships within the global OSAT and backend manufacturing ecosystem are preferred.
