Mainframe CICS & MQ Systems Programmer (z/OS)
You will be responsible for the installation, configuration, maintenance, performance tuning, and security of IBM CICS Transaction Server and IBM MQ on z/OS. This role ensures high availability, resilience, and optimal performance for mission‐critical workloads, leveraging CICSPlex SM for multi‐region management and automation.
Key Responsibilities
Platform Engineering & Lifecycle Management
* Install, Upgrade, and Maintain IBM CICS TS and IBM MQ using SMP/E.
* Configure and customize CICS regions (TOR/AOR/FOR) and manage CICSPlex SM for workload balancing, routing, and centralized administration.
* Configure MQ Queue Managers, Queues, Channels, Clusters, and Queue Sharing Groups.
* Maintain technical documentation and automation artifacts for deployments and recovery.
Performance, Capacity & Reliability
* Monitor and tune CICS regions and MQ subsystems using RMF/SMF, OMEGAMON, Sysview or equivalent.
* Analyse and resolve complex incidents (dump analysis, abends, queue depth anomalies, channel failures).
* Design and test high‐availability patterns using CICSPlex SM and MQ clustering; participate in Disaster Recovery exercises.
Integration & Developer Enablement
* Define and manage CICS resources (programs, transactions, URIMAPs, PIPELINEs) and MQ objects (queues, topics, channels).
* Provide technical guidance to application teams on CICS‐MQ integration and performance‐aware design.
* Collaborate with z/OS System Programmers, Db2 DBA's, Security, and Network teams for end‐to‐end reliability.
Security, Compliance & Automation
* Implement RACF/ACF2 security for CICS regions and MQ resources.
* Build automation and alerting (REXX, JCL, z/OSMF workflows) to improve resiliency and reduce manual effort.
Required Qualifications
* Expertise in IBM CICS TS architecture, configuration, and tuning on z/OS.
* Strong knowledge of CICSPlex SM for multi‐region management.
* In‐depth knowledge of IBM MQ administration on z/OS.
* Strong z/OS fundamentals: JCL, TSO/ISPF, SMP/E, JES2, SMF/RMF.
* Proficiency in scripting/automation (REXX, JCL; z/OSMF desirable).
* Familiarity with DB2, IMS, and performance tooling (OMEGAMON, Sysview).
Preferred Experience
* MQ/CICS integration for high‐volume workloads.
* Advanced dump analysis and coordination with IBM support.
* Exposure to modern patterns (APIs, cloud‐adjacent integration, Java/COBOL services).
Core Competencies
* Analytical problem solving under pressure.
* Cross‐functional collaboration with AppDev, DB, Security, and Operations.
* Ownership and reliability with on‐call participation.
