Mainframe Datacom Engineer

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.

• Strong hands-on Broadcom Datacom or CA Datacom DBA experience.
• A proven ability to diagnose and fix Datacom issues, not only monitor and escalate them.
• Strong experience in backup and recovery, database administration, restoration and performance or query tuning.
• Hands-on Datacom patching, maintenance and system programming experience.
• Strong IBM z/OS and JCL knowledge.
• Experience supporting enterprise-scale production Datacom environments.
• Ability to work independently with minimal training or supervision.
• Strong troubleshooting, analysis and problem-solving skills.
• Ability to work Mexico-aligned hours.

Preferred:

• Spanish language capability, particularly for working with Spanish-speaking users and team members.
• CICS, COBOL and wider mainframe application knowledge.
• Banking or financial services experience.
• Db2 knowledge (advantageous, not required).
• Experience in regulated enterprise environments.
