• Maintain structured governance, escalation and exception logs, dashboards and supporting records to strengthen transparency and audit readiness.
• Support period-end activities, reconciliations, reporting and performance reviews across AP and AR, working with Record-to-Report and other Finance teams as required.
• Collaborate with Procurement, Commercial, Sales, Customer Service, Supply Chain, Treasury, Finance, markets and external partners to resolve cross-process issues and improve outcomes.

• Experience using enterprise resource planning systems such as SAP S/4HANA, together with reporting, workflow or finance operations tools.

• Proven stakeholder management and communication skills, with the ability to work effectively across functions, markets, regions and external service partners.
• Ability to manage competing priorities and deliver high-quality outputs in a fast-paced, changing environment.
• Continuous improvement mindset, with experience contributing to process standardisation, automation, system enhancement or transformation initiatives.
