About team

Business Platform Development Department, Warizan Group

You will be assigned to the Business Platform Development Division of the Money Forward Business Company, which handles the Business domain supporting the Money Forward Group. The Business Platform Development Division was established to maximize the value of "Money Forward Cloud," which supports the efficiency of back-office operations and management improvement in Japan.

This division develops cross-functional concerns related to Money Forward Cloud. It is divided into multiple teams and focuses on developing services used across the board rather than being limited to specific services. The division also engages in activities aimed at eliminating technical debt on a project basis.



Assigned Team: Warizan Group

Money Forward Cloud offers various services, supported by numerous microservices running behind the scenes. The Warizan Group is responsible for developing and operating multiple business platform microservices.


Team Vision

Money Forward Cloud provides over 30 services, with microservices as common functionalities. The number of products is expected to increase in the future. Currently, Money Forward Cloud accounts for over 60% of Money Forward's total revenue.

The Warizan Group focuses on the new development, stable operation, implementation support, and feature development of microservices. By extracting common components as microservices, the group aims to create an environment where each service team can focus on delivering user value.


Job Description

The team uses Scrum development and does not separate backend and frontend teams or tasks. Given the current team balance, we aim to strengthen the recruitment of engineers with expertise in backend development. Additionally, Money Forward plans to switch to full English development by the fiscal year 2025, and the Warizan team is already advancing globalization efforts. 


Current Challenges

Need for Microservices:

With the increasing number of services offered, information about businesses and employees is maintained across various services. As the business scale grows, microservices are needed to enhance the development experience by extracting common components.


Consolidation of Management Functions:

There is a need to aggregate functions of management screens used by internal members, such as marketing and customer support.


Member Development:

The team mainly consists of members in their second or third year of development experience. While the environment is conducive to new challenges, the team also requires guidance and advice to support the growth of its relatively inexperienced members.


Resource Optimization:

The team manages the microservices infrastructure. As service integrations increase, so does the number of requests, necessitating regular resource monitoring and infrastructure adjustments. The environment allows for tackling infrastructure challenges.


Support for Service Integration:

The value of microservices is realized not just through their development but also through their actual implementation and use. The Business Platform Development Division develops microservices across multiple divisions, requiring communication, planning, and documentation to facilitate easy integration into each team.
