About this role

WealthNavi, Japan's leading robo-advisor, is building new products on top of its investing service, including "MAP AI", an AI-based life-planning service that draws on the MUFG group's customer base. The New Business Product Engineer (Frontend) works on these new businesses, centred on frontend development while making technical and product decisions together.

In this early phase, product managers, engineers and the business side step into each other's areas. The engineer helps set requirement priorities, makes specifications concrete, judges whether a release is ready, and decides scope and a small-start roadmap that balances customer experience, operating load and technical limits. Duties include requirement definition with business departments, frontend design, development and code review, and technology and architecture choices.

Applicants need frontend development experience with Next.js, experience driving requirements, scope and progress in development projects, leading prioritisation with the business side, and finishing projects in uncertain conditions. Architecture leadership, zero-to-one product experience, team management and backend experience are preferred.
