Quality Assurance Specialist - System Division, Rakuten Bank, Ltd. (Secondment)
RakutenThe System Division is an organization where you can engage in all tasks related to all system, such as planning, development, operation and maintenance, etc., ranging from developing core business systems to smartphone applications for iPhone / Android. It takes the important role as IT that determines the failure or failure as the social infrastructure--banking business while it aims to create new value with differentiated products of other banks. Here, people inside and outside the Bank who comes from different country share the strengths and the passions with each other to make innovation. For the growth in future, we seek new members. Rakuten Bank's value lies in providing excellent financial services that satisfy our customers. We are looking for a key professional to oversee quality management for our entire banking system—from requirements definition to production operations—to ensure that the most convenient, safe, and secure financial services are available to everyone. Our mission is not to execute tests, but to design and improve development processes that prevent bugs from being introduced into our banking systems. We promote Quality Engineering by visualizing quality risks in systems built by development teams and embedding quality into the product before release. Our role is to build governance and process improvement mechanisms that enable development teams to maintain high quality autonomously. We do not perform test execution or bug reporting. Instead, we structurally extract risks through the analysis of design documents and development processes. This is a highly strategic position focused on upstream problem-solving, identifying and preventing the structures that create bugs. Moving beyond intuition and experience, we conduct detailed analyses of past incident data and development metrics. Using data as an objective foundation, we engage relevant departments to instill a quality culture and ensure concrete improvement measures are embedded in the field. When incidents occur, we identify process defects and rethink our architectures and development/operation processes. You will develop professional expertise as a Process Architect who eliminates the root causes of quality issues. Working closely with development, operations, and infrastructure teams, you will act as a quality expert rather than a mere coordinator. You will visualize quality risks using data—such as identifying high-risk phases and methods to reduce incidents. By formalizing and visualizing these insights, you will evolve and standardize our quality processes into a more consistent, organization-wide framework. As one of Japan's largest internet banks, Rakuten Bank continues to provide innovative financial services rapidly. Our top priority is to guarantee the quality of our services, where Safety, Security, and Convenience are our greatest values. Our System Quality Assurance department is evolving from simple monitoring of development processes to Quality Engineering to design processes that prevent bugs. We are looking for a specialist to lead the forecasting of quality risks and the optimization of processes based on data, in close collaboration with relevant departments across the entire system development lifecycle. We are looking for someone who does not just point out violations of development rules, but explains the technical necessity of quality requirements and drives improvements by gaining consensus through close collaboration; someone who discusses issues based on facts—such as logs and metrics—rather than emotions, and makes objective judgments; and someone who can firmly assert the importance of quality when trade-offs with deadlines or costs arise, and ensures the organization's quality standards are upheld through close coordination with relevant departments. You will oversee the entire process from requirements definition to production release, ensuring development is conducted according to regulations and preventing quality risks. You will review requirements documents, design specifications, and test plans from a third-party perspective to detect quality fluctuations early and provide advice for improvement. You will quantitatively analyze defect convergence and trends to determine release readiness. When quality issues or risks arise, you will provide countermeasures based on logical evidence and drive improvement initiatives with relevant departments. You will identify technical and process defects for production incidents and formulate and execute organization-wide recurrence prevention measures.
