About this role
Leaders AI is an organizational transformation product jointly developed by DeNA AI Link and THA for enterprise customers. It converts the thinking and decision criteria of executives and business leaders into AI so employees can receive advice based on their company’s philosophy, strategy, and culture through a business chat tool. The product includes interviews, learning from internal materials, and accuracy adjustment, with an implementation process described as taking about three months.
The Product Manager owns the overall product direction and leads major issues across go-to-market, growth, product experience, and AI functionality. Responsibilities include defining target enterprise segments, working with sales and marketing, analyzing barriers to adoption, and testing improvement hypotheses. The role also designs and improves contextual UX for Chat UI and dashboards, establishes feedback loops, monitors KPIs, and drives recurring improvement cycles.
The position defines requirements for AI interview functionality, including LLM application design, prompt design, and RAG construction, and directs the web frontend and server-side development teams. It also designs how work should be divided between AI and people during each phase of product development and incorporates AI agents into team workflows. The role involves agreeing on specifications and priorities with business leaders, engineers, designers, external partners, and customers.
Additional responsibilities include designing implementation flows for enterprise customers, creating mechanisms to support operational adoption, maintaining a medium- to long-term product roadmap, and making decisions based on competitor and market analysis. Knowledge gained through work, including failed approaches, is expected to be shared with other teams to strengthen product development capabilities across the organization.
The team follows an AI-native development approach in which Product Managers develop with Claude Code and actively integrate AI agents into daily workflows. The role is primarily office-based for team collaboration. Listed work locations are the DeNA Shibuya office in Tokyo or two offices in Yokohama, with remote work permitted from home or another company-approved equivalent location. The listed offices are indoors non-smoking, with designated indoor smoking areas.
