  • Support finance stakeholders with analysis and interpretation of financial data.
• Partner across finance and technology:
  • Act as a trusted advisor to Finance, Business Controlling, and IT stakeholders.
  • Support users with system-related issues, reporting logic, and process improvements.
  • Challenge existing ways of working and identify opportunities to improve decision-making through data and digital tools.
  • Align business requirements with technology capabilities to create sustainable solutions.
