Tech Lead - EC Logistics Development Department (ECLD)

Job Description:

Business Overview

When you see the word "Rakuten", you probably have an image of many e-commerce-related services such as "Rakuten Ichiba", "Rakuten Books", and "Rakuten Fashion". 

If you order items from these services, it is commonplace every day that the items will be delivered to your home. So, where and how are these items managed, how are they boxed, shipped, and delivered to your home? In fact, these parts that you cannot directly see are the scope of responsibility of EC Logistics Development Department, which we are in charge of. 
 

Department Overview

We operate a number of warehouses in Japan where we store and manage Rakuten Books, Rakuten Fashion, and Rakuten Direct items, and perform tasks such as receiving and shipping. In addition, we have developed a service called "Rakuten Super Logistics" and receive items from merchants in Rakuten Ichiba, and we also do item-related work on behalf of them. 

What is necessary for the series of operations in this warehouse is the system developed by the EC Logistics Development Department. If our system stops, items purchased through e-commerce will not be delivered, and the only direct contact with customers is "logistics (delivery)". Logistics has a strong impression of being behind the scenes, but it plays such an important role. 

In addition, while managing these systems close to the "site (warehouse)", the control of the "estimated delivery date" displayed on Rakuten Ichiba, the "delivery status display" from the purchase history on Rakuten Ichiba, and the "delivery related notification" are also part of the system that our department is in charge of. 

In this way, we, the EC Logistics Development Department, develop and operate the "logistics" that support the Rakuten Group and the "systems" that support it in general. 

• ECLD's Mission:
• 1. To realize a service that allows shoppers to get "what you want" "when you want it" and "where you want it" by utilizing logistics and IT. 

1. 2. To provide convenient logistics services and functions to shoppers so that they can enjoy shopping. 
2. 3. To support the operation of Rakuten Ichiba merchants from a logistics perspective and contribute to maximizing sales. 
3. 4. Contribute to the development of Rakuten Ichiba by expanding the above logistics system.
