Senior Frontend Engineer, Money Forward Cloud, Fukuoka

In product development, the frontend domain covers a wide range of areas close to the user, such as appearance, performance, and accessibility, and there are many challenges in the products currently under development.

We are working daily to solve these challenges and enhance value for users. New product development is also gradually progressing, and the team is becoming capable of development in a modern environment. We are looking for engineers who can focus on enhancing user value in the frontend domain at the Fukuoka base.
