Job: EMC Storage - GDDR SRDF Location: (Remote) Duration: 8 month(s)

We are seeking a senior-level Dell EMC Mainframe Enablers (MFE) / Geographically Dispersed Disaster Restart (GDDR) Engineer to provide specialized production support for a large, highly available mainframe storage environment. This is not a general EMC storage administrator role. The successful candidate must have hands-on experience troubleshooting GDDR/MFE automation, SRDF replication and recovery issues in production, including situations where automation fails or stops mid-process and manual intervention is required. The engineer will work alongside infrastructure and multivendor support teams during critical incidents to diagnose failures, determine appropriate recovery actions, restore replication safely and provide mainframe-specific guidance based on array-side conditions.

Required Technical Experience:
Candidates must have strong hands-on production experience with: Dell EMC Mainframe Enablers (MFE) Dell EMC GDDR / GDR, preferably GDDR 6.x GDDR configuration, scripts, overrides and automation GDDR restart and recovery procedures
Failure handling when GDDR automation stops or fails mid-process SRDF/S and SRDF/A AutoSwap and consistency-group operations zDP Symmetrix command-line tools
Mainframe storage operations FICON and Fibre Channel concepts related to EMC mainframe replication
Replication drops and failed automation Resynchronization and full-push scenarios
Recovery following script interruption Device and consistency-group cleanup/reconditioning
Coordination of array-side conditions with host-side recovery
Determining when replication can safely be resumed
Experience supporting MFE/GDDR environments involving VMAX 950F and/or PowerMax 8500 is strongly preferred.

Production Support Responsibilities

The engineer must be capable of independently troubleshooting situations including:
GDDR or MFE automation failures
Automation stopping during an active process
SRDF/A or SRDF/S replication drops
Scripts requiring backup, restart, bypass or manual completion
Devices or consistency groups requiring cleanup or reconditioning
Failed or interrupted replication recovery
Host-side recovery resulting from array-side conditions
Determining whether conditions are safe to restart/resume replication
Sev 1 and Sev 2 production incidents requiring immediate technical escalation

Primary Skills
During major incidents, the engineer will participate in live technical bridges with client, infrastructure and vendor support teams and provide clear recommendations for recovery.
Support and On-Call Expectations

The engagement requires:
Participation in a 24x7 on-call rotation for critical Sev 1/Sev 2 incidents
Primary and backup coverage
Remote incident response
Live bridge participation during major production incidents
Review and analysis of logs, command output, configurations, case history and runbooks
Environment familiarization and knowledge transfer
Documentation of support procedures, known issues and escalation paths
The position is not intended to replace Dell engineering for product defects, firmware/microcode issues or vendor-only fixes. The engineer will, however, be expected to isolate problems, document technical findings and assist with escalation to Dell when required.
