Brand

At Post Consumer Brands, we’ve spent generations showing up for families, starting with breakfast, the most important meal of the day. Our cereals have become a trusted part of daily routines, helping spark conversations, fuel busy mornings, and create everyday moments that bring families closer together, including their furry four-legged family members who have recently become a part of our story.

As families have evolved, so have we. What began at the breakfast table has expanded into snacks, peanut butter, and pet food, because caring for a family means feeding every part of it. With the addition of several iconic pet brands, we’ve extended our purpose: to make high-quality, accessible food for everyone under the same roof.

This phase is still new, and that’s what makes it exciting. As we continue to grow across grocery and pet, we’re looking for people who care about good food, thoughtful work, and the kind of impact that stretches from store shelves to kitchen tables, and food bowls, across the country.
