You have:

• Strong functional expertise in SAP FI/CO, particularly FI-GL, FI-AA and financial closing processes.
• Proven experience with SAP S/4HANA, ideally including ECC to S/4HANA Brownfield migration projects.
• Excellent communication and stakeholder management skills, with the ability to translate complex SAP concepts into clear business language.
• Fluent English is required; Dutch is a strong advantage.
