**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. **Key Responsibilities** **Your role and 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. **Required Technical And Professional Expertise** - 5+ years of hands-on experience administering IBM MQ in distributed and/or cloud environments. - Strong proficiency with RDQM setup and management - Experience in JMS/JNDI configuration - Solid understanding of MQ HA mechanisms - Familiarity with Linux-based MQ deployments and MQ control commands. - Excellent communication, troubleshooting, and documentation skills - MQ monitoring experience **Preferred Technical And Professional Experience** - Cloud deployment experience, preferably on Google Cloud Platform (GCP) with GKE, Compute Engine, or Cloud Run. - Certifications: IBM MQ Administration (v9.1 or higher), AWS/GCP Cloud Certifications, or IBM MQ on Cloud Developer Essentials.
