## Description

We are seeking an experienced Mainframe IBM MQ Engineer with strong hands-on expertise in IBM MQ for z/OS to support highly available, business-critical mainframe environments.

The successful candidate will be responsible for the administration, configuration, monitoring, performance, security, maintenance, troubleshooting, and lifecycle management of IBM MQ infrastructure on z/OS. The engineer will work closely with application, CICS, IMS, network, security, operations, and other mainframe infrastructure teams.

Responsibilities:

 * Install, configure, administer, and support IBM MQ for z/OS environments.
 * Configure and maintain MQ queue managers, queues, channels, listeners, transmission queues, and other MQ objects.
 * Perform day-to-day administration and monitoring of MQ environments.
 * Configure and support distributed queuing and communication between queue managers. IBM identifies communication between queue managers and distributed queuing as part of MQ for z/OS configuration.
 * Configure, administer, and troubleshoot IBM MQ clusters.
 * Monitor queue depths, channel status, queue manager availability, message flow, and overall MQ infrastructure health.
 * Troubleshoot production problems including:

 * Channel failures
 * Queue manager problems
 * Message delivery issues
 * Messages remaining on queues
 * Connectivity problems
 * Security/authorization failures
 * Application-to-MQ connectivity issues

 * Perform problem determination and root cause analysis for MQ-related production incidents.
 * Support MQ recovery and restart activities.
 * Support MQ upgrades, migrations, maintenance, patching, and lifecycle management.
 * Support high-availability and disaster-recovery requirements for MQ environments.
 * Configure and support MQ connectivity with mainframe applications, including CICS and IMS. IBM documents dedicated MQ adapters/bridges for interaction with both CICS and IMS.
 * Partner with RACF/security teams to implement and maintain MQ security.
 * Support channel authentication, connection authentication, TLS, and MQ access controls, where applicable. IBM documents channel authentication, TLS, security exits, and RACF access considerations for MQ for z/OS.
 * Analyze MQ performance and implement tuning recommendations.
 * Develop and maintain JCL, operational procedures, automation, and technical documentation.
 * Participate in production changes, implementations, incident management, and problem management.
 * Provide on-call and after-hours support for critical production issues when required.
