Job Description: Business Overview The Ad & Media Company provides advertising and marketing services, including digital advertising, market research, and influencer marketing. A key strength of the company is its ability to offer end-to-end solutions covering every aspect of marketing - from upstream strategic planning to downstream execution, such as ad operations, performance measurement, and data analysis. Our marketing-related operations encompass a wide range of businesses, including "Rakuten Marketing/LinkShare" (providing comprehensive digital marketing solutions), "Rakuten Data Marketing" (offering solutions that leverage Rakuten’s proprietary big data), and "Rakuten Insight" (providing market research services). This environment allows you to work within a core division of the Rakuten Group while fostering your own professional growth and career advancement.   Department Overview Backed by the extensive resources of the Rakuten Group, Rakuten Insight Global provides online research services to companies worldwide. Operating as the global headquarters overseeing 11 locations across the globe, the company is aggressively driving expansion from Japan into international markets. Our greatest strength lies in possessing one of Asia’s largest proprietary panel data infrastructures; moving forward, we intend to accelerate the development of next-generation research products by fully leveraging this asset. To achieve further global market expansion, we are accelerating the growth of our network panels and intensifying strategic procurement efforts. This team serves as the core organization driving these initiatives.   Position: Why We Hire As the demand for research in global markets grows, our reliance on "external panels" to complement our proprietary panels has increased year by year.

We are now entering a phase where we aim to resolve these procurement inefficiencies and fundamentally overhaul our supplier strategy. We are seeking a manager candidate capable of leading "strategic sourcing" - an approach that goes beyond mere cost reduction to optimize the balance between quality and cost - thereby strengthening the medium - to long-term revenue foundation of Rakuten Insight Global.   ・Lead sourcing strategies that drive business profitability Sourcing costs and quality directly impact business profitability.
