In this role, you will be responsible for ensuring accurate and timely financial and statutory reporting, maintaining compliance with local and United States Generally Accepted Accounting Principles (US GAAP) requirements, and producing robust process documentation.

• An accounting degree (Chartered Accountant, Association of Chartered Certified Accountants, Certified Public Accountant, or local French equivalent).
• Fluency in both French and English with excellent communication and team‑building skills.
• A proactive, self‑starting mindset with a proven problem‑solving skill set and the independence to challenge the status quo.
