## Description

Our client is looking for a Mainframe Datacom Engineer to provide hands-on BAU support and technical ownership of an existing CA Datacom environment on IBM z/OS. The role runs alongside a wider modernisation programme and focuses on maintaining and supporting the current Datacom estate, rather than production monitoring or a Datacom-to-DB2 migration.

What you will do:

 * Administer and maintain Broadcom Datacom databases on z/OS.
 * Diagnose, troubleshoot and resolve Datacom database issues independently.
 * Carry out backup, restore and recovery, and database administration and structuring.
 * Diagnose and resolve database and query performance issues.
 * Perform and support Datacom fixes, patching, patch validation and maintenance.
 * Provide Datacom technical consultancy and support to applications and users.
 * Carry out root cause analysis and implement permanent fixes.
 * Take ownership of BAU Datacom activities transferred from the existing team.
 * Work with application, operations and infrastructure teams to maintain service stability.
 * Produce and maintain technical documentation and operational procedures.
