The Role

------------

We’re looking for our first Director of Finance to build and scale the financial foundation of Gray Swan as we enter our next phase of growth.

Reporting directly to executive leadership, this is a highly visible role that combines strategic finance with operational execution. You’ll own the company’s financial planning processes while building the systems, reporting, and operational rigor needed to support a rapidly scaling business.

This is not a role where you’ll simply oversee the work of others. We’re looking for a working director—someone equally comfortable owning the monthly close process, building complex financial models, implementing systems, preparing board materials, and partnering with leadership on strategic investments.

If you enjoy building from scratch, solving complex business problems, and operating with high ownership in a fast-moving startup, we’d love to talk.
