Rakuten is seeking a Java Software Engineer for its Shipping Calculation Platform within the EC Logistics Development Department. The role involves designing, developing, testing, and maintaining reliable services that calculate shipping options and costs for e-commerce operations. Candidates are generally expected to have professional Java development experience, knowledge of object-oriented design, databases, APIs, and software development processes. Experience with Spring, cloud environments, microservices, distributed systems, or logistics platforms is advantageous. The successful candidate should be comfortable working in English and Japanese multicultural teams, communicating clearly with product and engineering stakeholders, and taking ownership of production-quality systems. Strong problem-solving skills, attention to detail, and a willingness to improve platform performance and scalability are important.

The company has an international workforce and promotes a global working environment, with English widely used in many corporate and engineering teams. Rakuten invests heavily in technology, including cloud platforms, data, artificial intelligence, mobile networks, and logistics infrastructure. Employees typically work on services used by large customer and merchant communities, offering opportunities to develop systems at significant scale. Benefits and working arrangements vary by position, department, and employment contract.
Japan offers strong opportunities for software engineers, especially in Tokyo, Osaka, Yokohama, Nagoya, and Fukuoka. Demand is steady in web development, cloud computing, cybersecurity, data, fintech, robotics, and telecommunications. Japanese workplaces value reliability, teamwork, preparation, and respectful communication, while international companies may operate mainly in English. Tokyo provides excellent public transport, restaurants, entertainment, and career options, but housing and commuting can be expensive. Other cities often offer a lower cost of living and a slower pace. Foreign professionals usually need an appropriate work visa, commonly an Engineer/Specialist in Humanities/International Services status, with employer support for sponsorship. Applicants should prepare academic and employment documents and confirm eligibility before relocating. Japan has efficient healthcare, safe cities, and convenient infrastructure, although learning basic Japanese greatly improves daily life. Relocation planning should include housing deposits, registration, taxes, insurance, and adaptation to local customs.
