Senior Software Engineer (Accounting Development Division)

Overview

At Money Forward, we develop and provide the B2B SaaS "Money Forward Cloud." Among these services, the cloud accounting service has achieved significant growth in the market of accounting service cloud accounting. The accounting service holds the potential to support and accelerate users' businesses by automating and streamlining many tasks.

However, many small and medium-sized businesses (SMBs) still face challenges such as inefficient accounting processes reliant on paper and lack of transparency in business information, with low productivity emerging as a significant societal issue.

We collaborate with partners who support SMBs and sole proprietors, such as accounting firms and tax offices, as well as the government, which is driving the digitalisation trend, to continuously improve ‘Money Forward Cloud Accounting’ and increase the number of users. Our goal is to enhance the operational productivity of domestic companies and, ultimately, the overall competitiveness of the domestic business sector.

On the other hand, Money Forward Cloud Accounting is a mission-critical system that already supports the operations of many users, and stable operation is essential for users to use it with peace of mind in their daily work.

Maintaining stable operation while continuing to evolve a mission-critical product that handles vast amounts of data and is used by many users is a highly challenging task that is difficult to experience at other companies.

To achieve this, we believe it is essential for both the team and individuals to continuously improve their skills, and we are taking various actions to this end.

• Recruiting technical advisors who are experts in their respective fields
• Providing support for developing the development environment, including subsidies for book purchases, conference attendance fees, and technical training
• Conducting internal study sessions
• Contributing to open-source software (OSS)

We are seeking individuals who are willing to join us in overcoming this challenging task and working together to shape the future of our company.
