Role Overview

We are seeking a Controller who will own Arbor's core accounting operations and build scalable financial infrastructure as the company grows. You'll manage outsourced accounting operations, lead ERP implementation, establish manufacturing cost accounting, and build grant compliance capabilities — all while ensuring accurate, timely, audit-ready financials.

This role requires strong judgment, comfort with ambiguity, and a bias toward building scalable systems and processes. You'll partner closely with the Director of Finance (who owns forward-looking FP&A and modeling) to ensure historical actuals are accurate and provide the foundation for strategic planning.

The Controller is backward-looking and compliance-focused, answering the question: "Are the books right?" You'll ensure Arbor has clean books, compliant processes, and scalable accounting infrastructure.

Audit, Tax & Compliance
