Job description

Fresh Food, Happy Dogs.

We believe dogs deserve the healthiest, most natural and tastiest meals - with none of the nasties. That's why we make FRESHly prepared food, cooked just like you would at home and delivered direct to our customers in perfect portions. As a B-Corp certified company, you're joining a sustainable business that genuinely cares about our people, our products and our impact on the planet. Our goal is simple: to help dogs live healthier, happier, and longer lives, while leaving humans smiling after every interaction.

We've come a long way since our co-founders (Kev & Dave) hand-delivered the very first Butternut Box. Today, we feed hundreds of thousands of hungry dogs across the UK and Europe - but we won't stop until we're feeding dogs everywhere. To get there, we need a team of brilliant people who share that ambition.

The job:

This role sits within the Product Development team, reporting to the Product Development Director. You'll own our Additional Products category end-to-end, spotting opportunities, shaping concepts, delivering launches, and deciding what stays, grows, or goes. You'll also own product lines across wellness, gifting, food and non-food, combining the customer rigour of an innovator with the execution focus of an NPD lead, always raising the bar on how and what we deliver while staying true to the customer and ensuring every product has a clear reason to exist.

The nitty-gritty:

This role is UK-based in either London or our kitchen in Doncaster. It's a 15-month maternity cover , with genuine potential to stay with us beyond the placement if you're successful in the role and interested in moving into another role at a relevant level within the team or wider squad.

A bit about the team you'll be joining:

We're a hybrid squad working across the UK, owning the product pipelines for both Butternut Box and Marro. We're the foundation of what the business builds: great food, strong nutrition and products that genuinely improve pets' health. We own what the physical product looks like and how it delivers real benefits for dogs and cats. We're deliberately lean and close-knit, so everyone gets stuck in, has real ownership and plenty of opportunity to develop and progress. What brings us together is a deep belief in our products, our category and the power of fresh food to improve pets' lives.
