Rakuten is seeking a Data Scientist for the Customer Service Development Department at Rakuten Payment, working on payment and customer-service products. The role is expected to analyze customer and operational data, develop predictive or optimization models, identify service issues, and translate findings into product improvements. Candidates should have practical experience with Python or R, SQL, statistics, machine learning, data visualization, and large-scale data handling. Experience in customer analytics, fintech, payments, recommendation systems, or business problem-solving is valuable. Strong communication skills are required to work with product managers, engineers, and business teams. The successful candidate should be comfortable explaining technical results clearly, taking ownership of projects, and working in a fast-paced, collaborative, multicultural environment. Japanese proficiency may be important for internal coordination, while English is commonly used across Rakuten.
Rakuten Group, founded in Japan, is a major technology and internet-services company operating a broad ecosystem that includes e-commerce, fintech, mobile communications, digital content, travel, advertising, and professional sports. Its membership and loyalty platform connects many of these services, allowing customers to earn and use Rakuten Points across the group. Rakuten Payment, Inc. focuses on payment and financial-service products such as online payments, point services, and merchant solutions. The company promotes innovation, data-driven decision-making, and collaboration across diverse business units. Rakuten employs people from many nationalities and has a strong international outlook, although Japanese is often important in Japan-based roles. Employees may work with large customer datasets and products used by millions of people. Benefits and working arrangements vary by position, and compensation generally reflects experience, skills, and responsibility.
Japan offers strong opportunities in technology, data science, finance, engineering, healthcare, tourism, and education, especially in Tokyo, Osaka, Nagoya, and Fukuoka. The culture values punctuality, respect, teamwork, and careful attention to quality. Workplaces can be structured, though international companies are often more flexible. Lifestyle ranges from dense, convenient city living to quieter coastal and rural communities. Public transportation is excellent, healthcare is accessible, and daily life is generally safe, but housing in Tokyo can be expensive. Foreign professionals usually need a work visa, commonly sponsored by their employer; highly skilled workers may qualify for a points-based visa or faster permanent-residence pathway. Applicants should prepare academic certificates, employment records, and translated documents. Learning Japanese improves workplace communication and everyday integration. Relocation costs, apartment deposits, taxes, pension, and health insurance should be planned before arrival.
