■ Job Description

You will participate in projects that continuously develop systems as a DX partner for client companies, primarily responsible for backend development.

Your responsibilities will cover a wide range, including system architecture design, external system integration, API design, database design, DDD-based design, implementation, testing, and release.

Additionally, you will have opportunities to challenge cloud infrastructure setup (mainly PaaS) and CI/CD pipeline configuration.

If desired, you can also be involved in frontend development.

■ Development Style

Our development approach centers around teams. Teams continuously engage with projects, understand the client's business, and optimize processes as needed.

We proactively adapt to business changes to maximize client value.

We maintain close communication with clients to clarify requirements, verify developed applications, and discuss necessary adjustments.

For unclear requirements, we create prototypes to collect feedback and refine the specifications.

We use ticket management systems and online meeting tools for daily interactions, ensuring remote collaboration without requiring on-site presence at client locations.
