Software Engineer III-IIDR - IBM InfoSphere Data Replication

Position Summary

This job is responsible for developing and delivering complex requirements to accomplish business goals. Key responsibilities include ensuring software is developed to meet functional, non‑functional, and compliance requirements, and solutions are well designed with maintainability, ease of integration, and testing built in from the outset. Job expectations include strong knowledge of development and testing practices common to the industry and design and architectural patterns.

• Codes solutions and unit test to deliver a requirement/story per the defined acceptance criteria and compliance requirements
• Designs, develops, and modifies architecture components, application interfaces, and solution enablers while ensuring principal architecture integrity is maintained
• Mentors other software engineers and coach team on Continuous Integration and Continuous Development (CI-CD) practices and automating tool stack
• Executes story refinement, definition of requirements, and estimating work necessary to realize a story through the delivery lifecycle
• Performs spike/proof of concept as necessary to mitigate risk or implement new ideas
• Automates manual release activities
• Designs, develops, and maintains automated test suites (integration, regression, performance)
• Lead the design, development, and implementation of real‑time data replication solutions using IBM IIDR to support Never Down (NVD) initiatives.
• Own end‑to‑end delivery of IIDR‑based pipelines across mainframe (z/OS) and midrange platforms, ensuring seamless integration with DB2, Kafka, and other target systems.
• Troubleshoot and resolve complex replication issues, with a strong focus on reducing latency and ensuring high availability and resilience.
• Optimize performance of IBM IIDR CDC pipelines, including tuning throughput, subscription parallelism, and resource utilization.
• Provide technical leadership and mentorship to engineering teams, driving best practices in IIDR design, development, and support.
• Collaborate with cross‑functional teams to define requirements, estimate effort, and deliver solutions aligned with business priorities.
• Ensure production stability by monitoring system health, proactively identifying risks, and implementing remediation strategies.
• Support testing, deployment, and release activities, including CI/CD processes and production readiness validations.
• Conduct root cause analysis for incidents and implement long‑term fixes to improve system reliability.
• Drive continuous improvement and innovation through proof‑of‑concepts, automation, and process enhancements.

• 10+ years of hands‑on experience (Technical developer) in IBM IIDR (mainframe and midrange), focused on real‑time data replication, configuration, monitoring, and troubleshooting in data integration pipelines.
• Deep knowledge of IBM IIDR across z/OS (mainframe) and IIDR midrange (Linux/Red Hat) environments.
• Strong proficiency in z/OS and Unix technologies, including JCL, DB2 for z/OS, RACF security, and Unix shell scripting; well versed in IIDR‑to‑Kafka streaming architecture.
• Proven ability to tune IBM IIDR performance between source and target data stores (log readers, buffers, throughput optimization, and subscription parallelism).
• Hands‑on experience with IBM IIDR Access Server and Management Console configuration.
• Strong troubleshooting skills with expertise in analyzing IBM IIDR logs, DB2 logs, Mainframe SYSLOG / JES logs.
• Skilled in analyzing network issues affecting replication; communication/handshake issues; serialization or conflict errors; schema evolution problems across IBM IIDR and Confluent Kafka.
• Identifying performance bottlenecks such as high CPU usage in IIDR CDC capture; log volume spikes; locking/contention issues on source or target systems and subscription parallelism.
• Experience working with heterogeneous data environments (DB2, Oracle, Single Store, Cockroach DB). Perform root cause analysis for replication failures.
• Subject matter expertise supporting near real time log based solutions, monitoring IBM IIDR health, latency, and overall pipeline performance.
• Ability to perform root cause analysis and drive…
