•             Implement integration security: TLS/mTLS, OAuth/JWT, Basic Auth, certificate management.

•             Troubleshoot and optimize integration flows for latency, throughput, parser efficiency, and memory footprint.

•             Participate in CI/CD pipelines, automated deployments, unit testing, and environment migrations.

3. IoT & Telemetry Messaging (IBM MQXR / MQTT)

•             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.

4. 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.

5. 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.

•             Ensure platform hardening, certificate rotation, and vulnerability remediation.

6. Automation, DevOps & Observability

•             Create automation scripts (Shell, Python, PowerShell) for deployments, housekeeping, and monitoring.

•             Build IaC templates (Ansible, Terraform) for consistent provisioning.

•             Integrate platforms into CI/CD pipelines (Jenkins, Azure DevOps, GitLab CI).

•             Maintain dashboards for real time system health and SLA adherence.

7. Documentation & Collaboration

•             Create runbooks, SOPs, operational guidelines, and architectural diagrams.

•             Work closely with application teams, architects, network, cloud, and security teams.
