About this role

Maintain and develop the customer-management functions of a core credit-card system at the client’s Takadanobaba site. Responsibilities cover enrolment, screening, card issuance and member management, taking requests through design, development, testing and production release. The engineer works in a four-to-nine-person team and helps clarify and coordinate customer requirements, with future scope to take a leadership role.

Applicants need at least one year of COBOL system development spanning detailed design, coding and unit testing. Production-release experience, previous leadership, mainframe operations and credit-card business knowledge are preferred rather than mandatory. The environment includes COBOL, SQL, JCL, z/OS and DB2. Work is normally on site, with occasional home working open to discussion and possible night or holiday responses roughly every two to three months.
