System Engineer – AS400 is responsible for the day-to-day administration, availability and performance of THE CLIENT's IBM i (AS400) platform, which hosts business-critical JD Edwards and Lawson workloads. The role covers operating system and DB2 administration, LPAR management, and the supporting Brocade SAN fabric.

This position is being established in India as a designated back-up to the single AS400 resource THE CLIENT retains in the United States, providing continuity of coverage for the platform through its remaining lifecycle.

• Management of the AS400 operating system and DB2 database environment.
• Support and administration of three production instances of JD Edwards running on AS400.
• Support and administration of multiple JD Edwards development environments.
• Management of LPARs (logical partitions) across the IBM Power estate.
• Management of the Brocade switches and SAN fabric supporting the AS400 stack.
• Support and administration of the Lawson application, which is also hosted on AS400.
• Act as back-up to the US-based AS400 resource, ensuring continuity of platform coverage.

The successful candidate will operate within the following THE CLIENT infrastructure landscape:

• Compute & virtualisation: VMware vCenter, Nutanix, hyperconverged compute (Dell VxRail), Dell PowerEdge, IBM Power / IBM i (LPARs). Total server estate of approximately 371 servers.
• Storage & backup: IBM storage array, Amazon S3 / Wasabi, Veeam, IBM SAN fabric (Brocade on the AS400 stack), and KeepIt for Microsoft 365 backup.
• Database: Microsoft SQL Server and AS400 DB2, including one production MS SQL Always On cluster across three nodes, generating approximately 10 incidents per month.
• Cloud: AWS (Redshift) and Azure (Azure SQL Server).
• Service management: ServiceNow Zurich release, with limited CMDB and CI maturity at present.
• Documentation: Knowledge management and standard operating procedures are currently very limited on the infrastructure side.

Engagement Context & Platform Roadmap

Candidates should be aware that the AS400 platform is on a defined decommissioning path:

• THE CLIENT retains one AS400 resource in the US and has requested a back-up resource be hired in India — this role.
• By end of 2027, two of the three JD Edwards instances will be migrated to Oracle Cloud Infrastructure (OCI) and managed by Oracle.
• The remaining instance is the Protein instance, located in Alabama.
• Lawson will be migrated to Microsoft Dynamics.

Given the limited existing knowledge management and SOP coverage on the infrastructure side, a meaningful part of this role will involve documenting the environment to support a clean transition and eventual decommissioning.

• Good years of hands-on experience administering IBM i / AS400 environments in a production setting.
• Strong working knowledge of IBM i operating system administration and DB2 for i, including performance tuning, journaling and backup/recovery.
• Demonstrated experience with LPAR creation, configuration and management on IBM Power hardware (Power 9 or comparable).
• Practical experience administering SAN fabric and Brocade switches, including zoning.
• Experience supporting ERP workloads on IBM — JD Edwards strongly preferred, Lawson advantageous.
• Working knowledge of CL programming and IBM job scheduling and subsystem management.
• Experience operating within an ITIL-aligned service management model, ideally using ServiceNow.
• Ability to work effectively across time zones with a US-based counterpart, including participation in an on-call rotation.
• Exposure to ERP migration or platform decommissioning programmes, particularly JD Edwards to Oracle Cloud Infrastructure.
• Familiarity with adjacent infrastructure technologies in the estate: VMware, Nutanix, Dell VxRail, Veeam, Microsoft SQL Server.
• Strong technical documentation skills, with a track record of building SOPs and knowledge articles in a low-maturity documentation environment.
• Scripting capability (CL, Python or PowerShell) for automation of routine operational tasks.
• ITIL Foundation certification (desirable).
