Position Details

We are hiring a prospective leader with strong communication skills who can proactively raise and drive the resolution of challenges within a diverse engineering team and organization. Depending on your preference, you may also be involved in development management work.
This position is for an engineer to take charge of the business-logic development, system maintenance, and architecture improvement of the mainly API-centric data integration layer known as "Warehouse Gateway (WHGW)."
WHGW sits between the following two systems:
The Order Management System (OMS), which handles Rakuten users' order data (purchase information).
The Warehouse Management System (WMS), which manages the entire flow of products in the warehouse, including inbound, outbound, and inventory management.
WHGW occupies an indispensable position connecting these two systems, and is regarded as a critical system that must process a large volume of order information accurately and quickly every day.
To further develop this system and make it more stable, we are looking for a candidate who can become an engineering leader in the near future. You will mainly be responsible for the following:
Creating system requirements, functional requirements, and architecture requirements
Developing project plans and work plans; estimating personnel and equipment costs
Basic design; infrastructure and middleware procurement; log collection and management
Release planning and execution
System operations design, execution, and troubleshooting
Application development for high-load transactions, and design and execution of performance testing
Implementation (including code review)

Work Environment

Across the entire department, roughly 160 members are active, spanning both Japan and overseas.
The group you will belong to is an organization of about 10 members.
Many members join us with experience in software development as product managers or engineers, but most of them had no background in logistics and acquired the domain knowledge only after joining our department.
As our application platform, we primarily work with an in-house Private Cloud environment.
