Technical Project Manager SAP / S/4HANA Rollout

Project overview

We are looking for a "Technical Project Manager SAP / S/4HANA Rollout" for one of our clients.

As part of an S/4HANA brownfield rollout, we are connecting our local unit to the standardized corporate template and completely replacing existing legacy systems (Work4All, FileMaker). As Technical Project Manager, you will manage external implementation partners and ensure holistic data migration and system integration up to the Go-Live in July 2027.

• Utilization: approx. 50%
• Mainz / Remote (individual and flexible split possible)

Responsibilities

Partner & Project Management: Operational management of external SAP service providers, plausibility checks of deliverables, effort estimations and change requests (scope, budget, quality) as well as milestone and risk tracking together with internal project management.

Corporate Interface: Technical coordination with the central IT of the parent company to ensure compliance with architecture, template, and governance specifications.

Data Migration (ETL): End-to-end management of the migration from Work4All and FileMaker to S/4HANA – from cleansing, data architecture, and field mappings to mock migrations and the final cutover.

Cross-Module Integration: Ensuring smooth process and data flow across the core modules MM, WM-HUM, PP, SD, and FI to avoid interface breaks between logistics and finance.

Testing & Go-Live: Planning and tracking of all test phases (SIT, UAT), technical defect management with partners, and development of robust cutover and emergency/rollback scenarios.

Our Requirements

Mandatory Criteria:

• Project Management Experience: Several years of demonstrable success as a Technical Project Manager or Integration Manager in complex SAP projects (preferably brownfield or rollout scenarios).
• S/4HANA & Corporate Know-how: Sound understanding of S/4HANA architectures and solid experience in projects where existing corporate templates were adapted.
• Process & Module Knowledge: Comprehensive interface and integration competence in modules MM, WM-HUM, PP, SD, and FI.
• Migration Experience: Practical experience in migration projects taking over data from non-SAP source systems (experience with Work4All or FileMaker is a strong plus).
• Provider Management: Assertive, confident management of external IT service providers and software implementers.
• Language Skills:
• German: Business fluent
• English: Business fluent
• Mobility: Willingness for planned on-site assignments at the Mainz location (e.g., for project kick-offs, integration workshops, test phases, and during Go-Live).
