SAP S/4 Project Manager (m/f/d) for a Brownfield Migration - from October - 24 months - fulltime

Project overview

we are looking for an SAP S/4 Project Manager (m/f/d) for a brownfield migration.

Responsibilities

– Overall program control: deadline, budget, risk, and dependency management across all sub-projects; management of the resolution, minutes, and open items regime (decision log, LOPs).

– Steering of the implementation partner, the hosting/technology service provider, and, if applicable, a separate HR partner through service specifications, milestones, and acceptances; claim and additional claim management.

– Functional plausibility check of migration and cutover concepts, custom code and data cleansing approaches, Fiori/authorization concept, and test scopes; review of effort estimates and change requests before commissioning.

– Definition and enforcement of project guidelines (scope discipline, standard proximity, decision deadlines) — factual, written, escalatable; constructive counteraction in case of conflicting goals between stakeholders.

– Stabilization and enablement of business departments: realistic expectation management per project phase, early detection of overload, active escalation of capacity conflicts to the sponsor.

– Swift takeover of the project at the start: familiarization with contracts, offer bases, and tender documents; operationalization of acceptance criteria, change request regime, and hypercare SLAs in project governance.

– Structured knowledge transfer to internal roles as a contractually agreed component of the final project phase.

Requirements

– At least two, preferably three, supervised ECC-to-S/4HANA conversions (brownfield) as overall project management on the client side — not exclusively as delivery project management for a system house; referencable, at least one of which in the medium-sized business or retail sector.

– Sound assessment knowledge (no customization depth required) of New GL, Universal Journal (ACDOCA), Bank Account Management / electronic bank statement processing, custom code remediation, as well as Fiori authorization and SoD concepts.

– Proven management of multiple parallel external partners (multi-vendor) including claim and additional claim management.

– Strong moderation and escalation skills; sovereignty in controversial committees; the ability to enforce guidelines without damaging working relationships.

Desirable:

– Knowledge of HR/HCM integration (especially personnel cost posting / payroll posting) for evaluating variant decisions and HR interface governance.

– Experience with projects according to SAP Activate; corresponding certification.

– Industry experience in retail; experience with historically grown system landscapes and integration with external systems.
