About the position

As a senior backend engineer, you will be a primary contributor to business-critical microservices supporting the Money Forward Cloud product suite. We are in the process of breaking apart dependencies on a monolithic database, as well as creating new common data entities to be shared across products to improve development speed and cross product adoption by our customers.

We are looking for skilled backend engineers to help us design the most impactful common data entities, build reliable and easy-to-use API microservices to serve that data, and deliver a platform-wide impact to multiple product engineering teams.

About the team

You will be assigned to the Business Platform Development Department of Money Forward Business Company. The Business Platform Development Department was established to support the development of 'Money Forward Cloud,' a suite of products supporting Japanese back-office operations, including accounting, expense management, tax returns, and more.

One sweeping initiative underway now is the reduction of doubly maintained master data across different Money Forward Cloud products. By unifying shared data entities, we can reduce duplicate engineering efforts on product teams, and enable cross-sell wins more easily on our products.

Furthermore, we intend to continue this pattern and reduce our overreliance on a monolith database, so there is potential for a well-designed architecture to be utilized for multiple services and have a large impact across the business.


As a senior backend engineer, you will design Golang microservices that expose business critical data to our Money Forward Cloud applications. You will actively design database schemas, as well as data migration and reconciliation systems from multiple source databases into our target consolidated database. You will be part of architecting a data ecosystem that allows for multiple different query patterns, whether through traditional RDBMS SQL queries, or pub/sub via Apache Kafka. You will also help guide our customer teams (other Money Forward Cloud product engineering teams) through the integration process of the APIs we build.


  • Bachelor's degree in Computer Science, Engineering, or a related technical field.
  • 3+ years of web application development experience
  • Experience in golang
  • Experience with database design and modeling
  • Experience developing against a modern RDBMS (MySQL, Postgres, RDS/Aurora, etc.)
  • Experience in designing and deploying cloud infrastructure
  • Willing to learn Japanese
  • Be able to relocate to Japan and commute to the office in Tokyo at least twice a week

Nice to haves

While not specifically required, tell us if you have any of the following.

  • Conversational level of Japanese (N3+)
  • Experience with backend development with Ruby on Rails or Ruby
  • Experience with Kafka or other message broker technologies
  • Experience with data engineering – ETL pipelines, data processing jobs, or database administration
  • Experience with system architecture design
  • Experience with microservice development
  • Experience with devops or service reliability engineering
  • Experience with container based development


6.4 to 10 million JPY annually.
