In our Sole Proprietor Development Department, which is currently recruiting, you will be involved in product development primarily used by sole proprietors, focusing on income tax returns, consumption tax returns, and business startup notifications.

Our mission is "Moving work and life forward for individual workers." We aim to create a world where all individual workers are freed from the hassle of business operations and financial worries, enabling them to work with vigor.

We strive to make our products as user-friendly as possible, reducing the burden on users. We work closely with product managers and designers, and sometimes go beyond the boundaries of the product to achieve our mission, engaging in daily development efforts.

As an example, we are diligently working to integrate tax filing features into Money Forward ME, Japan's largest household accounting service, to realize a service that allows users to complete their tax filings without hassle or confusion.

To realize our mission, there are still essential things that we believe should be provided to users that have not yet been achieved. Naturally, the world we want to realize lies beyond that, and we are recruiting teammates to achieve this together.
