• Advisory & Growth Support
  • Provide finance guidance to support fundraising, board reporting, and investor relations
  • Identify opportunities for financial efficiency and improved margins

• Proven ability to create and maintain financial models and headcount plans
• Experience managing budgets, forecasts, and department-level financials
• Strong analytical, organizational, and communication skills
