We are looking for an experienced Mainframe Datacom Engineer/DBA to support an established Broadcom (CA) Datacom environment running on IBM z/OS.

This is a hands-on technical role requiring a specialist who can hit the ground running, take ownership of BAU activities and independently diagnose and resolve database issues with minimal training or supervision.

Key Responsibilities:

• Carry out root cause analysis and implement permanent fixes.

• Provide technical support to application, operations and infrastructure teams.

• Take ownership of existing BAU Datacom activities.

Essential Experience:

• Strong hands-on Broadcom/CA Datacom DBA or System Programming experience.

• Proven ability to independently troubleshoot and resolve technical issues.

• Experience supporting enterprise-scale production Datacom environments.
