Mainframe Automation Migration Engineer
Mainframe Automation Migration Engineer Location :: Remote Job Summary The Mainframe Automation Migration Engineer is responsible for migrating, modernizing, and optimizing mainframe batch scheduling and automation environments. The role involves migrating automation workloads from legacy scheduling tools to modern enterprise scheduling platforms, ensuring job dependencies, scheduling calendars, triggers, alerts, and operational processes are accurately transferred with minimal business disruption. The engineer collaborates with mainframe operations, application development, infrastructure, and production support teams to plan, execute, validate, and support automation migration projects. Key Responsibilities 1. Mainframe Automation Migration Analyze existing mainframe automation environments, job schedules, and batch processing workflows. Migrate automation jobs from legacy scheduling tools to target platforms. Perform job inventory, dependency analysis, and migration assessment. Map existing scheduling definitions, calendars, events, triggers, and conditions to the target scheduler. Develop migration plans, implementation strategies, and rollback procedures. Ensure minimal downtime and business impact during migration. 2. Mainframe Scheduling and Automation Configure, maintain, and troubleshoot enterprise job scheduling tools. Manage batch job dependencies, predecessor-successor relationships, and conditional processing. Work with scheduling calendars, time windows, job triggers, and resource constraints. Analyze job failures, abends, delays, and scheduling conflicts. Ensure successful execution of daily, weekly, monthly, and year-end batch cycles. 3. Tools and Technologies Depending on the project, experience may be required with: Mainframe platforms: IBM z/OS, JCL, TSO/ISPF, SDSF. Scheduling and automation tools: IBM Workload Scheduler (TWS/IWS), Control-M, CA 7, ESP, AutoSys, or equivalent enterprise schedulers. Scripting and utilities: REXX, JCL, UNIX shell scripting, Python, and automation utilities. Mainframe subsystems: JES2/JES3, VSAM, DB2, and CICS, depending on application requirements. Migration and validation: Job definition conversion, scheduling comparisons, dependency validation, reconciliation, and test automation. 4. Migration Testing and Validation Perform source-to-target job definition comparisons. Validate scheduling rules, job dependencies, calendars, and event-based triggers. Execute system integration testing, regression testing, and parallel-run validation. Verify job completion status, return codes, output files, and downstream dependencies. Identify and resolve discrepancies between legacy and target automation environments. Document test results and obtain business or operations sign-off.
