• Configure and support MQXR Telemetry listeners, MQTT topics, subscriptions, and QoS policies.
• Secure MQTT clients using TLS certificates, access control, and throttling policies.
• Monitor MQTT client connections, sessions, retained messages, and message routing to backend MQ systems.
• Workload Automation (IBM TWS / IWS)
• Install, upgrade, configure, and administer TWS/IWS masters, controllers, and agents.
• Build job streams, calendars, dependencies, event triggers, and SLA monitoring.
• Troubleshoot job failures, optimize schedules, and implement recovery workflows.
• Integrate workload scheduler with MQ, REST APIs, databases, file systems, and enterprise applications.
• Security, Governance & Compliance
• Implement end to end security for messaging and integration technologies:
  
  

TLS/SSL, mTLS, JAAS, CHLAUTH policies, RBAC, OAuth/SASL.

• Perform auditing & reporting for security compliance frameworks.
