Money Forward ME, the founding product of Money Forward, has become more complex in both system and specifications over its long history, increasing the difficulty of service maintenance and operation each year. Meanwhile, we have established a joint venture to provide new financial services and are transitioning the development and operation to the new company, moving to the next growth stage.
In this period of transformation, pursuing the essential value for users and developing without slowing down requires aligning the directions of business, product, and system, maintaining a balance between defense and offense in development capabilities.
Currently, the development team is globalizing and communication among engineers is shifting towards English. Additionally, members from overseas branches like Money Forward Vietnam are participating in development. While the common language within the engineering team is English, collaboration with our product managers, designers, and other roles is conducted mainly in Japanese. This provides an excellent opportunity for those who wish to challenge themselves and improve their Japanese language skills in a professional environment.
We are looking for individuals who can enjoy not only the growth of the product but also the growth of the team and themselves in such a challenging environment, and who can lead product development as a team leader!
