Job Opportunity

Senior Mainframe Operations & Service Integration Engineer

Contract to hire | Fully Remote

Overview

This is a critical operational role within a large enterprise environment supporting a complex mainframe estate undergoing ongoing transformation.

The position sits between internal application teams and a managed service provider (Wipro), acting as the primary point of coordination for incident resolution, operational support, and service integration across the mainframe environment.

This is a “control tower” role responsible for maintaining stability, improving coordination, and ensuring effective resolution of live production issues across multiple technical teams and vendors.

Experience Requirements

• Insurance or Financial service background is preferred
• Strong experience in mainframe operations or production support (not development-focused)
• Hands-on experience supporting COBOL-based applications in a production environment
• Experience working in complex, multi-vendor or MSP environments (Wipro is prefferd)
• Strong troubleshooting skills (log analysis, batch processing, incident diagnosis)
• Familiarity with systems such as CICS and DB2
• Ability to coordinate across infrastructure, application, and third-party support teams
• Strong communication and incident management skills in live production environments

Role Purpose

• The Senior Mainframe Operations & Service Integration Engineer will own day-to-day operational stability across the mainframe estate, ensuring incidents and issues are effectively triaged, coordinated, and resolved across internal and external teams.
• The focus is on strengthening incident management, reducing unnecessary escalations, and improving first-line resolution capability within internal support teams.
• This role requires strong collaboration across application support, infrastructure, and MSP environments, with a focus on clear communication and service accountability.

Key Responsibilities

• Act as the primary interface between application teams and the MSP (Wipro)
• Lead day-to-day mainframe operations support and incident coordination
• Manage infrastructure changes, upgrades, and release activities
• Own incident triage, troubleshooting, and escalation management across mainframe systems
• Work with application teams to diagnose and resolve issues before MSP escalation
• Coordinate support teams to ensure timely resolution of operational issues
• Support ESP Job Scheduler and batch processing environments
• Monitor service stability and identify recurring operational issues

A key objective is to improve operational ownership across the environment and reduce reliance on external escalation paths.

Why This Role Stands Out

• This is a high-ownership operational role at the center of a complex enterprise mainframe ecosystem.
• It offers significant visibility across internal teams and external managed service providers, with direct responsibility for how production incidents are managed, escalated, and resolved.
• It is well suited to someone who thrives in fast-paced operational environments and enjoys solving complex live service issues across multiple teams.
