Introduction

We are seeking an experienced IBM MQ Administrator with deep expertise in middleware messaging infrastructure and high availability (HA) configurations in on-premises and/or cloud environments. The ideal candidate will demonstrate proficiency in MQ queue manager lifecycle management, RDQM setup and troubleshooting, and JMS/JNDI integration to support Java applications. This role requires hands-on experience in HA clustering, DR replication (DRBD), and cloud-native MQ deployment patterns using GKE or Compute Engineer.

In this role, you'll work in one of our IBM Consulting Client Innovation Centers (Delivery Centers), where we deliver deep technical and industry expertise to a wide range of public and private sector clients around the world. Our delivery centers offer our clients locally based skills and technical expertise to drive innovation and adoption of new technology.

Your role and responsibilities

Key Responsibilities:

· Administer and support IBM MQ queue managers, ensuring reliable message delivery across distributed and clustered environments.

· Manage and maintain queues, channels, listeners, and transmission paths between multiple MQ instances, optimizing routing and performance.

· Implement and sustain high-availability and disaster recovery configurations, including replicated or quorum-based queue manager setups.

· Oversee queue manager lifecycle activities, including setup, configuration, and controlled decommissioning, aligned with enterprise change standards.

· Maintain data replication and synchronization mechanisms used for queue manager redundancy and failover protection.

· Analyze and interpret MQ logs, FDCs, and diagnostic reports to identify root causes, address system incidents, and prevent recurrence.

· Integrate JMS-based applications with MQ through standardized JNDI contexts and connection configurations, ensuring consistent and secure connectivity.

· Troubleshoot application-level connection issues across both bindings and client communication modes, ensuring low-latency and resilient operation.

· Validate and monitor HA group health, node quorum status, and replication states to maintain continuous availability of messaging workloads.

· Collaborate with middleware and cloud platform teams to design hybrid MQ topologies deployed across Linux and cloud (GCP/Kubernetes) environments.

· Ensure consistent configuration and operational compliance through infrastructure monitoring, alerting, and configuration baselining.

· Develop and maintain operational documentation, including topology diagrams, configuration inventories, and standard operating procedures.

· Partner with development and integration teams to optimize message persistence, routing, and throughput for business-critical applications.

· Participate in incident response and root cause analysis for messaging-related service disruptions.

· Mentor team members and promote best practices in MQ administration, HA management, and operational resilience.
