Senior mainframe Developer/Onsite coordinator

Responsibilities:

• Main Responsibility is to give 24*7 support for the current existing application
• Constructing and managing software in COBOL, PL1, VSAM, File-Aid, DB2, CA7. Preparation of Test plans, Unit testing and documentation of test results.
• Code changes to COBOL programs, preparation of Test plans, Unit testing and documentation of test results
• Quickly and knowledgeably respond to ESS healthcare end-user questions and issues prior to contacting the Shared Service Center
• CA-7 job scheduling / Abend resolution and JCL coding
• Understanding of the requirements and specifications from client and pass-through/explain in details to the offshore team
• Extensive use of VSAM files, using File-Aid for data-manipulations for batch procedures.
• Responsible for the creation, migration, and ownership of the schedules, JCL and PROC's, Parmlib's, and other batch resources. Both on and off the mainframe. Other than this, we have to take care of smooth-running and error-free environment and make sure that all work load SLA's are met for the current processing cycle.
• First-line of the triage of a production issue. Need to handle JCL errors, restarts, etc. In case of job failure, escalate issues that need more hands-on resolution, i.e. bad data, missing files, program abends, etc. Program and code fixes should be offloaded to the responsible applications support teams.
• Access to production data needs to be restricted. Data should be owned by the responsible application support team. There is always process in place to make a copy of the data available to those teams to initiate a fix without ever accessing the real data.
