The role involves designing, developing, and maintaining data pipelines and platforms supporting Rakuten’s Business Support System (BSS). Candidates are expected to have practical experience with Python, SQL, ETL or ELT processes, relational and NoSQL databases, data modeling, and cloud or distributed data technologies. Experience with system integration, large-scale data processing, monitoring, and software development practices is valuable. The successful candidate should be comfortable working across engineering teams, translating business requirements into reliable data solutions, and improving platform performance and quality. Strong communication skills are important in Rakuten’s international environment; Japanese ability may be advantageous, while English is commonly used across global teams.
Rakuten Group, Inc. is a major Japanese technology and internet company headquartered in Tokyo. Founded in 1997, it operates a broad ecosystem covering e-commerce, mobile communications, fintech, digital content, travel, online advertising, and other technology services. Rakuten’s membership and loyalty platform connects many of these businesses, allowing customers to earn and use Rakuten Points across the ecosystem. Rakuten Mobile and its related business-support systems are important parts of the company’s telecommunications expansion. The organization has a global workforce and employs engineers from many countries, with English frequently used in technical and corporate settings. Its culture emphasizes innovation, entrepreneurship, customer value, and collaboration. Working at Rakuten can offer exposure to large-scale platforms, international projects, and rapidly evolving digital products, although the pace and cross-functional nature of the business may require adaptability.
Japan offers strong opportunities in software engineering, data, cloud computing, telecommunications, finance, manufacturing, healthcare technology, and tourism. Tokyo has the largest concentration of international employers, while Osaka, Nagoya, Fukuoka, and Sapporo also provide growing technology markets. Japanese workplaces value punctuality, reliability, teamwork, and respectful communication; international companies may use English, but Japanese improves career and daily-life options. Living costs are highest in Tokyo, while regional cities can offer more space and lower rent. Public transport is excellent, healthcare is accessible, and Japan is generally safe, though earthquakes and typhoons are part of life. Most professional hires need an employer-sponsored work visa, commonly the Engineer/Specialist in Humanities/International Services status. Employers often assist with sponsorship and relocation, but candidates should confirm housing, taxes, insurance, and language support before moving.
