Experience eight years of experience in MQ Middleware to architect, implement, and maintain robust messaging solutions that integrate mission-critical mainframe systems with custom applications. The ideal candidate will be the organization's primary authority on IBM MQ on zOS, ensuring secure, reliable, and high-performance data exchange between distributed and mainframe environments.

Key Responsibilities

Architecture and Design

• Design and architect complex, high-volume MQ messaging infrastructures on mainframe (zOS) and distributed platforms, ensuring seamless integration with custom enterprise applications.

Installation and Configuration

• Lead the installation, configuration, tuning, and upgrading of IBM MQ (including Queue Managers, Queues, Channels, Listeners, and Clusters) in a zOS environment.

Integration Expertise

• Provide expert-level support and guidance for integrating new and existing custom applications (developed in Java, .NET, COBOL, etc.) with mainframe systems via MQ messaging.

Performance Tuning and Monitoring

• Proactively monitor MQ environments for performance bottlenecks and errors, implementing tuning strategies to ensure optimal performance, reliability, and high availability.

Troubleshooting and Support

• Serve as the final escalation point (L3 support) for complex MQ-related incidents, quickly diagnosing and resolving issues across integrated platforms.

Security Management

• Implement and manage security configurations, including SSL/TLS, channel authentication, and integration with mainframe security tools like RACF or ACF2.

Scripting and Automation

• Develop and maintain automation scripts (using JCL, REXX, Python, or Ansible) to manage, monitor, and deploy MQ objects and configurations.
