Rakuten is seeking a senior backend and platform engineer to improve the quality, security, and reliability of cloud services within its Cloud Strategy Office. The role typically requires strong experience with backend development, cloud platforms, distributed systems, infrastructure automation, testing, observability, and security practices. Candidates should be comfortable with languages such as Java, Go, or Python and technologies including Kubernetes, containers, databases, and CI/CD. The successful applicant will help define engineering standards, strengthen platform resilience, identify operational risks, and work with development and infrastructure teams across the business. Strong communication, problem-solving ability, ownership, and experience working in international or cross-functional environments are expected.
Rakuten Group, headquartered in Tokyo, is one of Japan’s largest technology and internet companies. Founded in 1997, it operates a broad ecosystem covering e-commerce, fintech, mobile communications, digital content, travel, advertising, and professional sports. The company’s services are connected through the Rakuten membership and loyalty platform, giving customers access to a wide range of products and benefits. Rakuten also develops significant internal technology platforms and cloud capabilities to support its global businesses. Its workforce includes employees from many countries, and English is commonly used in technology and corporate roles. Working at Rakuten can offer exposure to large-scale systems, international projects, and fast-moving digital businesses, although the environment may be demanding and highly collaborative.
Japan offers strong opportunities in software engineering, cloud computing, cybersecurity, data, finance, manufacturing, and international business. Tokyo has the largest technology market and the widest range of English-speaking roles, while Osaka, Nagoya, Fukuoka, and Sapporo offer growing alternatives with different lifestyles and costs. Japanese workplace culture values reliability, preparation, teamwork, and respect for hierarchy, though global technology companies are often more flexible. Daily life is safe, efficient, and convenient, with excellent public transport, healthcare, food, and public services. Housing and commuting costs are highest in Tokyo. Most professional employees need an appropriate work visa, usually sponsored by the employer; highly skilled professionals may qualify for a faster permanent-residency route. Candidates should prepare translated documents, arrange housing and registration after arrival, and learn basic Japanese for administration and everyday communication.
