About the Opportunity

We are seeking a hands‑on Interim Accounting Manager/Assistant Controller to support a high‑performing organization during a transitional period that includes a retirement and a summer leadership leave. This role is ideal for someone who thrives in a fast‑paced environment, enjoys being in the details, and is confident managing day‑to‑day accounting operations.

The ideal candidate is not looking for a strategic CFO‑level assignment—they are someone who can roll up their sleeves, stabilize processes, ensure accuracy, and keep critical accounting functions running smoothly.
