- Advanced Excel and financial modeling skills, with the ability to analyze large, complex datasets and translate findings into actionable recommendations.
- Excellent communication and business-partnership skills, including the ability to turn technical cost drivers into clear financial narratives for non-technical stakeholders.
- A bachelor’s degree in Finance, Accounting, Economics, or a related field.
