Responsibilities will include:

Operate z/OS JES3 operating system
Have sufficient technical expertise to monitor/maintain required customer response at all times
First level of error detection and diagnosis of all response time issues
Run daytime & nighttime production for EU & US systems
First level of error detection and diagnosis in all daily processes
Highlight and report on any failures, problem areas and incidents via Ops tickets
Maintain and monitor Ops ticket database and assign all tickets
Understand z/OS JCL and be able to perform initial problem diagnosis on failures
Produce clear incident reports and work logs via the ops ticket system
Communicate clearly and concisely with senior staff and on-call support staff during the problem resolution process

Who You Are:

Have sufficient technical expertise of z/OS, JES2 or JES3 operating systems, and related operating programs and facilities to effectively operate the Mediaocean mainframe system (TSO, ISPF, Ejes/SDSF, JCL, Beta92)
Work with self-initiative
Problem solving abilities
Knowledge of BMC AMIOPS, MAINVIEW and Control-M Tape would be an advantage
Knowledge of Jes3 DJC networking would be an advantage

This position follows a rotating overnight schedule consisting of 10-hour shifts from 8:00 PM – 6:00 AM, 4 days per week (Tuesday–Friday).

We would hate to miss out on your application because you do not meet every requirement – transferrable skills and education will also be considered, so please do not hesitate to apply!
