At Money Forward Inc., we continue to push the boundaries of financial innovation. With a diverse suite of over 50 B2C, B2B, and B2B2C services, our commitment remains unwavering: to make financial challenges easier to navigate for everyone. A key component of these services is the data collected through "account aggregation" technology. As the volume of such data increases annually, a highly scalable system architecture is essential to ensure that the data can be used stably by each service.

The CTO's office is looking for a team of individuals who can collaborate to develop a common infrastructure. This infrastructure will deliver large-scale data to the service side more quickly and robustly through a microservice that accesses such data.

Responsibilities and Duties

You will be tasked with setting project specifications and guiding the technical direction of our initiatives. You will establish a framework of technical standards and procedures to ensure consistency and oversee the quality of software and system modifications. Additionally, you will play a key role in guiding team members as they troubleshoot technical issues. Your responsibilities will also include analyzing existing operations to identify risks and redundancies, and conducting comprehensive assessments to develop innovative solutions that enhance system efficiency and reliability.

Additionally, you will gain extensive business knowledge, particularly in managing data systems through account aggregation and their application across services. You will also contribute to the planning and implementation of infrastructure measures that enhance service stability, complementing your primary responsibilities for technological advancement and operational excellence.
