Job Summary
We are seeking an IBM Mainframe Engineer with expertise in data center migration, consolidation, and modernization. This role is responsible for planning, executing, and optimizing mainframe migrations while ensuring high availability, minimal downtime, and data integrity. The ideal candidate will work with cross-functional teams to transition mainframe workloads from on-premise to new data center locations or cloud-hosted mainframes while adhering to industry best practices. 

Experience: 5+ years of relevant experience 

Client Location: Onshore, US
Mode of work: Remote; Needs to travel to client site when required by the client. Work Time Zone: EST or CST 

Detailed Job Description 

  • System Management: Oversee the installation, configuration, and maintenance of mainframe hardware, software, and operating systems. 
  • Performance Monitoring: Monitor system performance and ensure optimal operation by identifying and resolving performance bottlenecks. 
  • Security Management: Implement and maintain robust security protocols to protect mainframe systems from unauthorized access and cyber threats. 
  • Backup and Recovery: Develop and manage backup and recovery procedures to ensure data integrity and availability in case of system failures. 
  • Storage Management: Manage and maintain Mainframe Storage Arrays and File Systems including Virtual Tape systems and subsystems. 
  • Problem Resolution: Troubleshoot and resolve technical issues related to mainframe systems, ensuring minimal downtime and disruption to business operations. 
  • Capacity Planning: Conduct capacity planning and forecasting to ensure the mainframe environment can handle current and future workloads efficiently. 
  • Documentation: Maintain comprehensive documentation of system configurations, procedures, and changes for reference and compliance purposes. 
  • Support: Provide technical support and guidance to other IT staff and users regarding mainframe-related issues and queries. 

Key Responsibilities
1. Data Center Migration Planning & Execution 

  • Lead end-to-end migration of IBM mainframes from legacy data centers to new on-premise or cloud-based environments
  • Develop mainframe workload migration strategies, including LPAR, data replication, and application transition. 
  • Perform impact analysis, risk assessments, and dependency mapping before migration. 
  • Implement cutover plans, rollback strategies, and failover testing to minimize downtime. 

2. Mainframe Infrastructure Setup & Configuration 

  • Configure and optimize IBM zSeries (z/OS, z/VM, z/Linux) environments in the new data 

center. 

  • Manage LPAR provisioning, network segmentation, and workload balancing post-migration. 
  • Tune system parameters, workload scheduling, and CPU resource allocation to maintain 

performance. 

  • Ensure successful integration of migrated workloads with existing applications and 

databases.
3. Storage & Data Migration 

  • Perform high-volume data migrations using tools like IBM DataMover, DFSMS, and SRDF/EMC storage replication
  • Manage tape backup, virtual tape systems (VTS), and storage tiering for migration efficiency. 
  • Ensure DB2, IMS, and VSAM databases are securely migrated with minimal data loss. 
  • Conduct pre- and post-migration data integrity checks

4. Network & Security Compliance in Migration 

  • Implement mainframe network reconfiguration post-migration (TCP/IP, SNA, VTAM, OSA). 
  • Maintain RACF security policies during and after migration to ensure role-based access 

control (RBAC) compliance

  • Ensure encryption of in-transit and at-rest data meets regulatory standards (ISO 27001, PCI- 

DSS, GDPR). 

  • Work with security teams to implement firewall rules, VPN access, and multi-factor 

authentication (MFA) for remote mainframe users. 5. Performance Optimization & Troubleshooting 

  • Monitor CPU, memory, and storage utilization before, during, and after migration. 
  • Use tools like IBM OMEGAMON, MainView, and Splunk for performance tracking and issue 

detection. 

  • Optimize batch job execution, scheduling, and workload distribution post-migration. 
  • Troubleshoot CICS, DB2, MQ Series, and COBOL application performance issues related to 

migration. 

6. Disaster Recovery (DR) & High Availability 

  • Implement DR and failover mechanisms in the new data center. 
  • Conduct disaster recovery tests (DR drills) and failover validation to ensure business 

continuity. 

  • Integrate mainframe workloads with cloud-based DR solutions (IBM Cloud, AWS, Azure)

7. Documentation & Post-Migration Support 

  • Create runbooks, system configuration documentation, and migration reports
  • Document troubleshooting guides and knowledge base articles for ongoing support. 
  • Train internal teams on mainframe operations in the new data center environment
