• 3. Modernization & Automation Automation & Scripting: Write, maintain, and enhance ansible playbooks, python scripts, and REXX programs to automate DB2 deployment, routine maintenance, and multiple subsystems management tasks. CI/CD & API Integration: Integrate maintenance workflows into modern CI/CD pipelines using REST APIs and enterprise software development standards. Cross-Functional Collaboration: Partner with global development, operations, and cloud architecture teams to support continuous product delivery and infrastructure stability.

What You Need

• DB2 z/OS Systems Programming: Deep background in installing, configuring, upgrading, and maintaining DB2 subsystems on z/OS.
