Job Overview

We are seeking an experienced Mainframe DB2 Replication Engineer to design, implement, configure, and support data replication solutions across IBM z/OS and distributed environments. This role focuses on real-time data synchronization, Change Data Capture (CDC), high availability, and data consistency for mission-critical enterprise applications.

The ideal candidate will have strong expertise in DB2 replication technologies, mainframe systems, performance optimization, and real-time data streaming architecture.

Key Responsibilities

Replication Design and Implementation

• Design, install, configure, and maintain DB2 replication solutions across mainframe and distributed platforms.

• Develop and manage source-to-target data replication pipelines.

• Configure and maintain capture processes, apply processes, and control servers.

• Implement unidirectional and bidirectional replication solutions.

• Support real-time and near-real-time data synchronization.

Troubleshooting and Production Support

• Troubleshoot and resolve data inconsistencies, replication failures, queue backlogs, and network interruptions.

• Perform root cause analysis and implement corrective actions.

• Provide Level 2 and Level 3 production support for replication-related incidents.

• Monitor replication health and ensure data integrity and availability.

Performance Optimization

• Tune replication processes to reduce latency and optimize resource utilization.

• Implement MIPS reduction and optimization initiatives.

• Optimize data capture efficiency, apply performance, and network utilization.

• Minimize replication overhead and performance impact on source systems.

Integration and Data Architecture

• Support integration between DB2 for z/OS, DB2 LUW, distributed databases, messaging systems, and ETL platforms.

• Design and support real-time data streaming and replication architectures.

• Collaborate with DBAs, application teams, data engineering teams, and business intelligence teams.

• Support data migration, modernization, and hybrid data architecture initiatives.

Mainframe and System Administration

• Work with JCL, TSO/ISPF, SDSF, and mainframe batch and online environments.

• Support UNIX System Services (USS), including UNIX patch installation and maintenance.

• Develop and maintain UNIX scripts for administration, monitoring, and automation.

• Work with RACF for mainframe security and access control.

• Support replication infrastructure maintenance, monitoring, and operational improvements.

Required Qualifications

• Hands-on experience with DB2 for z/OS.

• Experience with IBM InfoSphere Data Replication (IIDR) and Change Data Capture (CDC).

• Working knowledge of IBM Q Replication; preferred for this role.

• Experience with ZDIH.

• Experience with MIPS reduction and mainframe performance optimization projects.

• Knowledge of replication architecture, data flow design, and CDC concepts.

• Experience with UNIX System Services, UNIX patch installation, and UNIX scripting.

• Knowledge of RACF and mainframe security administration.

• Strong troubleshooting skills related to data consistency, replication failures, performance, and latency.

• Experience with JCL, TSO/ISPF, SDSF, and mainframe batch and online processing.

Preferred Qualifications

• Familiarity with IBM MQ and other messaging systems.

• Experience with ETL processes and data warehousing platforms.

• Knowledge of monitoring tools and automation using REXX, Python, or shell scripting.

• Exposure to cloud-based and hybrid data architectures.

• Experience supporting large-scale data migration and modernization programs.

• Understanding of real-time data streaming architecture and enterprise data integration patterns.
