SAP Basis Consultant(L3)

This is a remote position.

SAP Basis Consultant (L3)

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.

Responsibilities

• Run, incident and root cause: 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.
  
• Transport, landscape and change: 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.
  
• Security patching and monitoring: 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.
  
• Near-zero-downtime patching (blue/green): 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.
  

REQUIRED

• 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.
  

PREFERRED

• 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.
