Notice Period-Immediate-10 days

The Quality Engineer - Mainframe ensures the quality of batch and online (CICS) mainframe applications by designing, executing, and automating robust tests across COBOL, JCL, DB2, and VSAM components. The role involves preparing test scenarios and data, executing test cases, validating databases and files, and logging defects in ALM/Jira. The engineer analyzes abends from JES spool, debugs using mainframe tools (e.g., Xpeditor), and reviews COBOL-DB2 code when needed. Collaboration with developers and leads is key to assess risks, report daily progress, and deliver on time, with hands-on use of tools such as File-Aid/File Manager, SPUFI, and Endevor.
