About the position

The “MoneyForward Cloud Series” is the core business of MoneyForward, which is a B2B SaaS.

“Cloud Accounting,” the first product in this cloud series, has been released for over a decade and currently boasts hundreds of thousands of users.

As a result of this extended period, there has been an accumulation of technical debt, and certain areas of the architecture remain unsettled. To address these challenges, the Architect department was established in July 2023.

The mission of the Architect department is to enhance the product’s architecture, streamline the development process, and improve its overall quality, specifically focusing on resolving the issues that have arisen over the years.


  • Server-side development of Cloud Accounting
  • Re-architecturing, Refactoring, Quality Improvements, etc.
  • Regardless of your job title, you will be involved in more than just writing code, as the entire team will be involved in reviewing specifications and considering improvements.


  • Bachelor of Science in Computer Science or comparable fields
  • Experience in web application development and operation in Ruby on Rails (>3 years)
  • Experience in team development using GitHub, CI, Lint, etc.
  • Experience with software architecture and being able to apply concepts to existing applications
  • Knowledge of SQL
  • Basic project management skills such as requirements definition, planning, estimation, and more. (Scale is not a concern.)
