Rakuten is seeking a Senior Infrastructure Engineer for its Core Technologies Section within the Corporate IT Infrastructure Department. The role is expected to design, build, operate, and improve enterprise infrastructure supporting internal business systems. Candidates should have substantial experience with servers, cloud platforms, networks, virtualization, monitoring, security, and infrastructure automation. Strong troubleshooting skills, documentation habits, and the ability to manage projects and external vendors are important. The successful candidate will work across teams, help define technical standards, improve reliability and security, and respond effectively to incidents. Business-level Japanese and English may be advantageous in Rakuten’s international environment, along with a proactive approach to continuous improvement.
Rakuten Group, Inc. is a major Japanese technology and internet company headquartered in Tokyo. Founded in 1997, it operates a broad ecosystem that includes e-commerce, online finance, mobile communications, digital content, travel, advertising, and professional sports. The company’s membership and loyalty platform connects many of these services through the Rakuten Points program. Rakuten has expanded internationally and employs people from many backgrounds, making English useful in several teams, although Japanese remains important for many domestic operations. Its corporate IT organization supports the systems, platforms, security, and workplace technology used across the group. Employees typically work in a fast-moving environment where large-scale operations, automation, reliability, and integration between businesses are important. Rakuten is known for encouraging innovation and internal collaboration, while the exact working style and benefits vary by department and employment contract.
Japan offers strong opportunities in cloud infrastructure, cybersecurity, software engineering, data, finance, manufacturing, hospitality, and teaching, especially in Tokyo, Osaka, Nagoya, and Fukuoka. Workplace culture often values punctuality, preparation, teamwork, and respect for hierarchy, though international technology companies may have more flexible practices. Japan provides excellent public transport, safe cities, efficient services, varied food, and a high quality of life, but housing and commuting costs can be high in Tokyo. Foreign professionals normally need an appropriate work visa, such as an Engineer/Specialist in Humanities/International Services visa; the sponsoring employer generally supports the application. Highly skilled professionals may qualify for faster permanent-residency pathways. Before relocating, arrange a residence card, municipal registration, health insurance, pension enrollment, housing, and a bank account. Learning practical Japanese greatly helps with daily life, administration, and wider career opportunities.
