Why We Hire

The Data Planning Section serves as a “strategic partner that maximizes advertising revenue through data and AI” for the Ad Sales Department. We leverage Rakuten’s vast data assets and cutting-edge AI technologies to elevate sales activities to a new level.

Attractiveness of the Business / Organizational Phase
As a core organization supporting the expansion of the Rakuten Group’s advertising business, we are in a new challenge phase aiming to redefine sales activities using data and AI. We are entering a stage beyond traditional sales support or analysis, where “systemized data utilization” is being implemented, offering substantial room for growth. Because the structure is not yet fully established, the ideas and execution of each member significantly influence future direction.

Attractiveness of Autonomy and Organizational Culture
In this organization, members have autonomy to propose and execute initiatives, regardless of title or tenure. The environment enables end-to-end involvement from building data utilization mechanisms to designing AI-driven proposal models and supporting implementation in the sales field. Data scientists, analysts, and sales teams collaborate in a flat structure, fostering a culture of “achieving results as a team.” With a culture that welcomes challenges and learns from failures, members can grow rapidly while enjoying the pace of change.

Career Steps (Skills and Career Paths You Can Build)
This position enables you to develop practical skills integrating data, AI, and business. By engaging consistently from advertising data analysis and AI model development to sales strategy and client problem-solving, you will refine your implementation capabilities and business transformation skills. A wide variety of career paths are possible, such as data-driven sales strategy leadership or product ownership for AI-driven initiatives.

Differentiation from Competitors (Leveraging Rakuten Group Resources)
Our biggest strength is the ability to utilize the Rakuten Group’s extensive data assets and its diverse ecosystem. By integrating data across EC, finance, travel, and more, we can scientifically maximize advertising effectiveness- an advantage unmatched by competitors. Collaboration with in-house AI and data-specialist teams provides direct access to cutting-edge technology and knowledge, enabling large-scale implementation of your ideas. As a result, you can experience the impact of being a strategic partner driving growth for the entire Group, rather than simply supporting sales.
