Senior Cost Accountant

At Stella & Chewy's, we believe pets deserve food as close to nature as possible — and that belief drives everything we do. From raw frozen dinners to freeze-dried treats, our products are crafted with purpose and made with real ingredients pets love. We're a mission-driven company with big growth ambitions, and we're building the team that will take us there.

This is a high-visibility individual contributor role sitting within the finance organization, reporting directly to the Senior Director of FP&A. You'll drive cost accuracy across our business, lead our annual standard cost roll, and work cross-functionally to evaluate the financial viability of new products before they ever hit a shelf.
