POSITION OVERVIEW

The Senior Accountant, SEC Reporting, position will play a key role in Collegium's external financial reporting, Sarbanes-Oxley (SOX) compliance, and equity administration and accounting. Reporting to the Assistant Controller, this role will own the end-to-end, day-to-day process for timely, accurate, and complete SEC reporting, including the Form 10-K, Form 10-Q, proxy statement, and other filings. The role will also be responsible for the timely and accurate processing of equity awards, ensuring proper process, accounting, and reporting. In addition, the Senior Accountant will serve as a key administrator for several financial systems, partnering with consultants, colleagues, and IT to ensure those systems operate effectively, remain SOX compliant, and continue to improve.

This position is ideal for a Big 4 auditor with public company experience who is ready to bring their audit skills into a growing public company. From day one, the Senior Accountant will help improve accuracy, drive deadlines, manage open items lists, and serve as a key point of contact for internal and external auditors.
