Rakuten

Data Engineer - EC Logistics Development Department (ECLD)

Tokyo, Japan
GCP Python SQL Machine Learning Java
Description

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. 

2. To provide convenient logistics services and functions to shoppers so that they can enjoy shopping. 

3. To support the operation of Rakuten Ichiba merchants from a logistics perspective and contribute to maximizing sales. 

4. Contribute to the development of Rakuten Ichiba by expanding the above logistics system 

 

Position: 

Position Details 

The purpose of this position is to support our business and development organization in making data-driven decisions from data processing. We utilize environments such as Google Cloud Platform (GCP) as our data platform. Moving forward, we are planning to enhance data visualization, predict logistics-related trends, and incorporate AI to enable faster business decision-making support and cost optimization. 

- Design, develop, and maintain scalable data pipelines and ETL processes to support data integration and transformation. 

- Collaborate with data scientists, analysts, and other stakeholders to understand data requirements and deliver high-quality data solutions. 

- Implement data quality checks and monitoring to ensure data accuracy and reliability. 

- Optimize and tune data processing workflows for performance and cost-efficiency. 

- Manage and maintain data storage solutions on GCP, including BigQuery, Cloud Storage, and other relevant services. 

  

Work Environment 

We have approximately 160 members actively working both in Japan and overseas. 

Many of our members join with experience as product managers or engineers in software development industry. However, most of them do not originally have a background in logistics and acquire their industry knowledge after being assigned to our department. 

We primarily utilize the internal Private Cloud environment, with some resources on Public Cloud.  
In development, team members with knowledge of Python, SQL, ETL, and Machine Learning are actively contributing. 

Mandatory Qualifications: 

- 3+ years of development experience using Python and SQL. 

- 2+ years of experience in data processing, data analysis or related fields. 

- 1+ year of cloud experience such as GCP.

- Strong communication skills with the ability to engage stakeholders. 

- TOEIC score of 800 or above or equivalent ability.

 

Desired Qualifications: 

- Knowledge of the logistics industry. 

- Experience in providing E-Commerce services (B2C, C2C, B2B2C). 

- Product management or project management experience. 

- Experience in developing and operating general business systems using programming languages such as Java. 

- Business-level Japanese proficiency.

As a student navigating the job market, I've found LinkedIn increasingly frustrating due to numerous fake postings by consultancies. In contrast, this job posting website has been a game-changer for me. It offers genuine opportunities and a straightforward application process, making it much easier to find and apply for real jobs. Highly recommend it to fellow students seeking reliable job listings!

Echo Jobs has been exceptional in my job hunt where it provides one platform to job hunt and I don't have to open 10 websites just to look for a job. It has also helped me focus much on the job skill and the location filtering out the onsite jobs and remote ones. The only feature that I would request is to display fully remote jobs that are not restricted to a country since the one available shows ie, Remote, US yet. But if it could show remote only, that would be helpful not only to me but to other people applying for full remote and not tied to only US candidates

I found EchoJobs in 2022, and I love it. It has a lot of remote jobs. It's exclusive to software and technology jobs (helpful for devs like me). What I like the most are its filters and its API. If you're a tech professional seeking remote work, I highly recommend giving it a try to EchoJobs.

Simply put, it's the most up to date tech jobs aggregator I’ve found. I'm like... "I don't have to check 10+ jobs boards daily just to see if there's a new job listing? sign me up!" The filters are also quite helpful! The UI is very clean and straightforward. Love it!
