Role & responsibilities

Role Summary

Provide L2/L3 production support and deliver enhancements for mission-critical applications running on IBM z/VSE in a 24x7 operations environment.
Lead P1/P2 incident bridges, restore service quickly, drive high-quality RCA, and implement preventive fixes that reduce repeat outages and protect shipping/plant cutoffs.
Support connectivity and interfaces (VSEn/VSE Navigator/TCP-IP, file transfers, partner integrations) critical to supply chain execution.

Key Responsibilities

Own end-to-end production support: incident triage, service requests, problem management, and resolution within SLAs.
Lead P1/P2 bridges: rapid triage, clear executive-ready updates, action/owner tracking, and post-incident follow-through.
Perform RCA (5-Whys/fault tree as appropriate) document corrective actions, and execute preventive improvements (monitoring, automation, runbooks).
Deliver enhancements: requirements clarification, impact analysis, design, build, unit/system testing, release, and hypercare.
Manage change/release activities: implementation & backout plans, approvals, deployment execution, and post-deploy verification.
Support batch/online stability aligned to operational timelines (batch windows, cutoffs, reconciliations, interface replays).
Coordinate across application,



infrastructure, network, security, and vendor teams; ensure audit-ready documentation and evidence.

Required Skills (z/VSE / Mainframe)

Strong hands-on IBM z/VSE production support (L2/L3).
VSE JCL: job setup, dependency handling, reruns/restarts, checkpoint/restart patterns.
VSE/POWER: spool/queue/output management and troubleshooting.
Batch operations: abend analysis, recovery steps, controlled data fixes/reprocessing.
Online support: CICS on z/VSE (region/transaction troubleshooting and recovery).
Data/files: VSAM concepts (KSDS/ESDS/RRDS), space/extend issues, integrity/reconciliation troubleshooting.
VSEn / VSE Navigator (as used): operational visibility, monitoring, and administration.
Connectivity/interfaces: TCP/IP troubleshooting, FTP/SFTP flows, file-based integrations, rerun/replay controls and reconciliation.
ITIL discipline: incident/problem/change management and solid RCA writing.

Development / Enhancement Skills (Required or Strongly Preferred)

COBOL (or equivalent) for debugging, minor-to-medium enhancements, and production fixes.
Strong testing and release support in controlled environments (segregation of duties, approvals, evidence).
