The Role

Your Role

As a Mainframe Operator, you will sit at the core of mission-critical delivery, operating and safeguarding high-availability IBM z/OS environments that run enterprise-scale customer workloads. You will oversee production health, batch cycles, and system performance, ensuring that core business operations run seamlessly, securely, and reliably around the clock.

In this role, you will act as a vital operational anchor—proactively catching anomalies before they impact the business and driving fast, structured incident triage when issues arise. Collaborating closely with cross-functional infrastructure, database, application, and network engineering teams, you will champion operational excellence and uphold rigorous enterprise standards.

What You Will Do

• Monitor and operate IBM Mainframe production environments via console management to maintain optimal system health, uptime, and performance.
• Manage end-to-end daily operations, including batch job scheduling, workload execution, console commands, and system health checks.
• Detect, triage, and resolve production operational incidents rapidly, coordinating escalations and root-cause investigations where necessary.
• Oversee business-critical processing schedules to guarantee the successful, timely completion of essential enterprise workloads.
• Partner with database, storage, networking, and application support squads to orchestrate incident mitigation and service continuity.
• Execute scheduled maintenance windows, system IPLs, change requests, and enterprise disaster recovery exercises.
• Maintain and enhance standard operating procedures, operational runbooks, and shift handover documentation.
• Participate in rotating shift patterns and on-call support schedules to ensure robust 24/7 coverage for critical production events.

• Demonstrated experience with operational incident triage, console alerts, performance monitoring, and rapid fault resolution in live production.
• Sound working knowledge of enterprise mainframe subsystems and security frameworks, including CICS, DB2, IMS, and RACF.
• Solid practical understanding of mainframe backup, restore, and business disaster recovery protocols.
• Demonstrated readiness to work rotating shift schedules to provide 24/7/365 production operational support.

Preferred Skills and Experience
