Job Description:

We are seeking an experienced Broadcom Datacom DBA / System Programmer to provide hands‑on BAU support and technical ownership of an existing CA Datacom environment on IBM z/OS. The candidate must have strong hands‑on Datacom expertise and be capable of independently diagnosing and resolving database and platform issues, performing fixes and maintenance, and supporting patching activities with minimal training. This is not a production monitoring role or a Datacom‑to‑DB2 migration role. The requirement is to provide specialist DBA support for the existing Datacom environment while the wider modernisation programme progresses.

Key Responsibilities:

• Administer and maintain Broadcom Datacom databases on z/OS.
• Independently diagnose, troubleshoot, and resolve Datacom database issues.
• Perform database backup, restore/recovery, and database administration/structuring.
• Diagnose and resolve database and query performance issues.
• Perform/support Datacom fixes, patching, patch validation, and maintenance.
• Provide Datacom technical consultancy and support to applications and users.
• Perform root cause analysis and implement permanent fixes.
• Take ownership of BAU Datacom activities transferred from the existing team.
• Work closely with application, operations, and infrastructure teams to maintain service stability.
• Produce and maintain technical documentation and operational procedures.
• Proven ability to independently diagnose and fix Datacom issues, not simply monitor and elevate production incidents.
• Strong experience in backup/recovery, database administration, restoration, and performance/query tuning.
• Hands‑on Datacom patching, maintenance, and System Programming experience.
• Strong IBM z/OS and JCL knowledge.
• Ability to operate independently with minimal training or supervision.
• Strong troubleshooting, analysis, and problem‑solving skills.
• Ability to work in Mexico‑aligned hours.
• Db2 knowledge is advantageous but not a requirement for the role.
