FUNCTION

The Controller will build and lead Standard Nuclear's accounting function from the ground up. This is a hands-on role focused on establishing core accounting infrastructure, implementing scalable systems and controls, and professionalizing financial operations to support rapid growth.

This is not a traditional Controller role overseeing an established department.

Over time, the Controller will hire and develop a team and transition into a scalable leadership role.
