SAP S/4HANA ERP Planning Lead (h/f)

Description

Lead end-to-end planning governance for a large-scale, multi-year ERP transformation built on SAP S/4HANA PCE and integrated with multiple satellite systems. The role is part of the core PMO and covers integrated planning through go-live of the first-out countries.

Main Responsibilities

• Maintain a reliable, integrated master plan through go-live of the first-out countries.
• Ensure the plan reflects real constraints, including resource availability, review cycles, training timelines and business blackout periods.
• Synchronize the master plan with workstream plans and backlogs, reconciling MS Project and Excel milestone sources into one coherent view.
• Maintain and actively monitor the critical path, flagging cross-stream conflicts and unrealistic overlaps.
• Scrutinize every re-baselining proposal, assess its impact on the critical path and commitments, and escalate risk.
• Guard against silent slippage, hidden buffers and over-optimistic sequencing.
• Cross-check the system integrator's plan and status claims against on-the-ground team feedback; challenge unrealistic or inconsistent reporting.
• Consolidate planning status by stream, verify RAG consistency, and deliver a reliable plan-on-a-page for steering committee governance.
• Provide structured planning input on trends, schedule risks and capacity tensions to program leadership.

Key Requirements

• 7+ years in project planning, scheduling or PMO on large transformation programs.
• Experience running planning for global SAP deployments, including core-template build, test, deployment and dual run with legacy systems.
• Strong MS Project expertise, including milestone management, dependency management, baselining, effort planning, and consolidation of multiple MS Project and Excel milestone plans.
• Working knowledge of Jira backlogs and sprints, with the ability to connect Agile progress to the integrated plan.
• Comfort operating in a hybrid delivery environment combining Agile sprints and Waterfall phases.
• Ability to constructively challenge and hold a system integrator accountable while maintaining an effective working relationship.
• Excellent written and spoken English; ability to present complex plans and status clearly and structurally.
• A structured, rigorous, reliable and solution-oriented working style.

Why This Role

Work at the center of a major transformation, with visibility across every workstream and direct exposure to program leadership and steering committee governance. Planning assessments directly inform decisions that shape go-live.
