About The Position

3Core Systems runs managed application services for SAP S/4HANA landscapes on SAP Cloud ERP Private, including sovereign-cloud deployments. We are hiring a senior Basis consultant to run technical operations on those landscapes. Your primary assignment is a newly onboarding US federal government end client, delivered under a major SAP partner acting as prime contractor. It is a greenfield landscape going live in mid-2026 — you will help establish how it is operated rather than inherit a runbook. You will also support other CAS engagements and share the practice on-call rotation. This is a run role, not a project role: keeping production healthy, patched, and available.

Requirements

6+ years hands-on SAP Basis administration with recent production ownership.
S/4HANA Basis administration in a live production landscape.
SAP HANA administration, including configuring, validating, or operating HANA System Replication and performing takeovers.
Transport management and multi-system landscape administration.
Analyzing and applying SAP Security Notes — assessing applicability, not applying everything.
Linux OS patching for SAP workloads.
Ticket-driven support (ServiceNow or equivalent) with evidence of performing to defined reaction-time SLAs.
Prior participation in a 24/7 production on-call rotation.
Able to write an RCA a non-Basis reader can act on.

Nice To Haves

SAP Cloud ERP Private / RISE with SAP, and familiarity with the provider-managed vs customer-managed boundary.
Sovereign or government cloud delivery; prior US federal or regulated-industry client.
Linux HA clustering (Pacemaker/corosync) in an SAP context; SAP BTP integration.
SAP certification in S/4HANA System Administration or HANA Administration.

Responsibilities

Continuous Basis administration of S/4HANA on SAP Cloud ERP Private.
Triage application Basis incidents falling outside the hosting provider's baseline product services; perform RCA and propose resolution, engaging SAP Product Support or cloud operations where the fault is platform-side.
Maintain the transport and deployment landscape and execute transport requests.
Maintain technical integration with adjacent SAP cloud applications, including SAP BTP.
Fulfil preapproved standard changes, and non-preapproved configuration changes once client approved.
Analyze SAP Security Notes on the monthly SAP Patch Tuesday cadence and deliver the applicability assessment within 24–48 hours of release a committed turnaround.
Implement approved notes to an agreed SOP.
Operate proactive monitoring via SAP Focused Run: health, job, integration, and exception monitoring; ABAP security parameters and privileges; ABAP work-process response time; data growth.
Remediate alerts in scope.
Proactive housekeeping of technical application data and logs.
Operate and validate SAP HANA System Replication between primary and secondary production systems.
Execute monthly OS and quarterly database patching via blue/green takeover; validate cluster and replication health either side of every takeover.
Maintain the patching cookbook and operational runbooks to a standard another engineer can execute from.
