Summary: The Mainframe Architect role focuses on designing and delivering near-real-time data integration from Mainframe DB2 to various downstream data platforms using IBM Change Data Capture (CDC). The position requires expertise in data modeling and mainframe data architecture, along with hands-on experience in enabling CDC-driven data pipelines. Collaboration with mainframe teams and data engineering is essential to ensure scalable and secure data movement aligned with enterprise standards.

Key Responsibilities:

  • Lead the architecture and design of CDC solutions using IBM Change Data Capture for Mainframe DB2 sources
  • Define end-to-end data flows from Mainframe DB2 to target systems (e.g., relational databases, data lakes, data warehouses, streaming platforms)
  • Design and govern logical and physical data models aligned with enterprise data architecture standards
  • Ensure data integrity, consistency, latency, and recovery in CDC-based replication and synchronization
  • Define standards for schema evolution, metadata management, and data lineage
  • Collaborate with application, mainframe, and data engineering teams to integrate CDC into broader data platforms
  • Support performance tuning, capacity planning, and operational stability of CDC solutions
  • Ensure compliance with security, regulatory, and data governance requirements
  • Provide architectural oversight, documentation, and technical leadership throughout delivery

Key Skills:

  • Strong experience as a Mainframe Architect / Data Architect
  • Hands-on expertise with IBM Change Data Capture (CDC) as a primary skill
  • Deep knowledge of Mainframe DB2 (data structures, performance, and utilities)
  • Proven experience in data modelling (conceptual, logical, physical)
  • Experience designing data movement from mainframe DB2 to distributed platforms
  • Strong understanding of data integration, replication, and near-real-time data processing
  • Knowledge of data quality, reconciliation, and error handling in CDC pipelines
  • Experience working in complex, large-scale enterprise environments
  • Experience with data lakes, data warehouses, or streaming platforms (desirable)
  • Familiarity with modern data architectures (event-driven, real-time analytics) (desirable)
  • Exposure to data governance frameworks and regulatory environments (desirable)
  • Prior experience supporting mainframe modernization or cloud migration initiatives (desirable)
