IBM DB2 z/OS Support & Automation Engineer

Role Overview

We are looking for an experienced IBM DB2 z/OS professional to provide operational support, implement Rundeck backup automation, assist with DB2 V13 upgrades, assess z/OS lifecycle supportability, modernize automation workflows, and deliver comprehensive documentation and knowledge transfer.

Key Responsibilities

IBM DB2 z/OS Support

• Provide day-to-day IBM DB2 operational support on z/OS.
• Support database refresh activities and generate DR/RR dumps.
• Troubleshoot DB2 issues triggered through application workflows or Rundeck.
• Act as the primary DB2/z/OS Subject Matter Expert.

Rundeck Backup and Automation

• Assess the existing Rundeck environment hosted on OCI virtual machines.
• Design, configure, and validate a backup Rundeck environment on OCI.
• Replicate jobs, scripts, plugins, configurations, and credentials securely.
• Ensure the backup environment can take over during primary-environment failure.
• Test artifact generation, dump-file extraction, and database creation workflows.
• Document backup, restoration, and failover procedures.

Automation Version Control and Documentation

• Inventory all Rundeck jobs, scripts, and automation assets.
• Store automation code and job definitions in Git or another version-control system.
• Prepare SOPs covering job execution, failure handling, and recovery.
• Create operational runbooks for routine support activities.
• Support switching between primary and backup Rundeck environments. DB2 V12 to V13 Upgrade
• Assess DB2 V13 installation and subsystem readiness.
• Identify and resolve integration issues between DB2 V12 and V13.
• Review relevant IBM PMRs and incorporate findings into internal documentation.
• Support DB2 V13 integration, compliance validation, and cutover planning. z/OS Lifecycle and Supportability
• Assess the current z/OS version and lifecycle status.
• Identify end-of-life and supportability risks.
• Recommend necessary upgrades or remediation measures.
• Ensure DB2 workloads remain fully supported on z/OS. Automation Modernization
• Identify Reflection-based scripts used for dump-file generation.
• Design and implement a supported replacement solution.
• Validate that the new automation reliably generates and tests database files. Workflow Analysis
• Reverse engineer and document workflows across Rundeck, DB2, z/OS, and downstream systems.
• Identify triggers, dependencies, hand-offs, and job-triggering mechanisms.
• Document primary and backup Rundeck execution paths.
• Eliminate undocumented or single-person operational dependencies. Security and Access Assessment
• Identify system IDs, service accounts, and credentials used across Rundeck, DB2, and z/OS.
• Document account ownership, usage, and access levels.
• Identify governance or security gaps and recommend remediation. Knowledge Transfer
• Provide hands-on training to the designated backup resource.
• Conduct cross-training on DB2 support, DB2 V13, z/OS workflows, Rundeck environments, automation, and security.
• Ensure the backup resource can independently operate both Rundeck environments.

Requirements

Required Skills

• Strong IBM DB2 administration and operational support experience on z/OS.
• Hands-on experience with Rundeck automation.
• Experience working with Oracle Cloud Infrastructure.
• Expertise in disaster recovery, backups, restoration, and failover.
• Experience supporting DB2 version upgrades, preferably V12 to V13.
• Strong understanding of z/OS operations and lifecycle management.
• Experience modernizing and migrating automation scripts.
• Knowledge of Git or another version-control system.
• Strong troubleshooting, documentation, SOP, and knowledge-transfer capabilities. Submission Note: Please share only two thoroughly screened profiles that strongly match the JD, location, budget, work mode, and immediate-joining requirement.
