At Money Forward, we provide services that solve financial challenges through the power of technology. Our Fukuoka Development Base is responsible for the development and operation of “Money Forward Cloud Expense,” one of our flagship services supporting a wide range of users, from sole proprietors to large corporations.
Since its release, Cloud Expense has grown into a large-scale product that supports businesses of all sizes, from startups to major enterprises. To maintain both “rapid feature delivery” and “high reliability” as we continue to scale, we are looking for a Customer Reliability Engineer (CRE) who embraces proactive operations—going far beyond simple maintenance and support.
We are seeking an engineer who wants to use their technical expertise to untangle complex domain challenges, work at the closest point to our customers, and safeguard system reliability through the power of engineering.
About the Fukuoka Development Base
Since opening in December 2017, Money Forward’s Fukuoka Development Base has steadily expanded alongside a growing community of talented engineers and designers.
In November 2025, we relocated our office to “Fukuoka Daimyo Garden City” to set the stage for our next chapter of growth. We are now aggressively recruiting engineers and designers to help our organization leap forward.
Our local vision is “Move Forward.” We place the highest priority on growth opportunities for every member, striving to be an energetic hub where everyone can boldly take on new technologies and complex challenges.
