The role requires strong professional experience in frontend development, ideally with JavaScript or TypeScript, React, HTML, CSS, and modern web application architecture. Experience building large-scale, maintainable platforms, working with APIs, testing, version control, and agile development is expected. Candidates should be comfortable collaborating with backend engineers, product managers, designers, and international teams. The successful applicant will help design, develop, improve, and maintain Rakuten’s BSS platform, while contributing to technical decisions, code quality, performance, and user experience. Clear communication, problem-solving ability, ownership, and a willingness to work in a fast-changing environment are important.
Rakuten is a major Japanese technology and internet services group headquartered in Tokyo. Founded in 1997, it operates a broad ecosystem covering e-commerce, fintech, mobile communications, digital content, travel, advertising, and professional services. Its businesses are connected through the Rakuten membership and loyalty platform, serving customers in Japan and international markets. Rakuten employs large, multicultural engineering teams and is known for promoting English as a common corporate language in many departments. The company invests heavily in cloud platforms, mobile technology, data, artificial intelligence, and digital customer experiences. Employees typically work in collaborative, fast-moving teams where they are expected to take ownership and contribute across organizational boundaries. The BSS Development Department supports business-support systems and platforms that help operate Rakuten’s complex digital services.
Japan offers strong opportunities for software engineers, especially in Tokyo, Osaka, Fukuoka, and regional technology hubs. Demand remains high for frontend, cloud, data, cybersecurity, and mobile specialists, with international companies often hiring English-speaking professionals. Japanese workplaces value punctuality, teamwork, respect, and attention to detail, although global technology firms may have more flexible cultures. Lifestyle choices range from energetic city living to quieter coastal or rural communities. Public transportation is excellent, healthcare is reliable, and daily life is generally safe, though housing and commuting in Tokyo can be expensive. Foreign professionals commonly use an Engineer/Specialist in Humanities/International Services work visa, usually supported by the employer; highly skilled professionals may qualify for preferential treatment. Relocating requires arranging housing, residence registration, insurance, banking, and possibly school or family support. Learning basic Japanese is highly recommended for administration and everyday communication.
