Head of Finance

ArboStar is a B2B SaaS platform for the tree care industry — one of the most underpenetrated vertical software markets in North America. We’re a team of ~100 people building a category-defining product, with customers across the US, Canada, Australia, and the UK.

We are looking for a strategic and hands-on Head of Finance who will take ownership of the company’s entire finance function and become a key business partner for leadership.

This role is ideal for someone who enjoys both high-level financial management and hands-on execution in a fast-moving environment.
