Our team is responsible for the development and operation of “Money Forward ID” and “EIAM,” which are mission-critical common platform supporting the entire Money Forward group.
This system is an authentication/authorization platform that supports over 30 products across the group and is a large-scale distributed system processing tens of millions of requests per day. We are looking for senior-level or higher engineers who can technically lead the evolution of the platform with expertise in Identity and Access Management (IAM), embodying “Platform Engineering” that improves the development experience and security standards of the entire group, beyond just single product development.
Tech Stack and Environment
Ruby and Kotlin are used as the main languages for the backend. We welcome those who have deep expertise in one and are willing to learn and utilize the other in practice.
The team consists of Japanese and multinational members, and daily communication and business operations are mainly conducted in English.
