About team

Business Platform Development Department, Cloud Partner Group

You will be assigned to the Business Platform Development Department of Money Forward Business Company, responsible for overseeing the Business Domains that support the Money Forward Group. The Business Platform Development Department was established to maximize the value of 'Money Forward Cloud,' which supports the efficiency and management improvement of Japanese back-office operations. We undertake development related to cross-cutting concerns of Money Forward Cloud, working across multiple teams to develop services that are not limited to specific services but are utilized across the board. Additionally, we engage in project-based technical debt reduction activities

We are currently seeking a development engineer for 'Cloud Partner,' a product exclusively designed for professionals (accounting firms and labor and social security attorney offices) available to certified members of Money Forward Cloud.



The Cloud Partner Group sets forth the product vision of "advancing the advisory experience for professionals." Professionals play a significant role in the growth of small and medium-sized businesses. However, they often dedicate a considerable amount of time to paper-based management tasks such as receipt management and various application form preparations, which hinders their ability to allocate resources adequately to advisory services for growth support.

Therefore, since our inception, we have been partnering with professionals and focusing on promoting the digital transformation of small and medium-sized enterprises (SMEs) through our back-office SaaS series, Money Forward Cloud. By 2023, our cloud accounting service became the No.1 choice among accounting firms, capturing a market share of 45%.

Currently, we provide features that support the management of clients who utilize the Money Forward Cloud series. However, going forward, our aim is to provide new value that enables professionals to focus more on supporting the business growth of small and medium-sized enterprises (SMEs).

We currently adopt Scrum development and do not divide teams or tasks between backend and frontend. However, considering the current balance of the team, we aim to strengthen recruitment efforts for engineers with expertise in backend development. Additionally, Money Forward aims to fully transition to English for development from the fiscal year 2025, and the Cloud Partner team is already progressing towards globalization.

Currently, the discovery phase, such as issue identification and requirement definition, is conducted by some members in Japanese, which is then translated into English. The delivery phase, including design, implementation, testing, and release, is entirely conducted in English. It is anticipated that the discovery phase will also be conducted in English in the future. However, breaking away from Japanese in product and business domains is challenging, so a combination of Japanese and English will be necessary for the time being.
