Senior Software Engineer

Changing the world of pet food for good

We're , a dog food subscription company with a big difference. We create truly tailored food for each and every dog we serve. We start by asking people a few simple questions about their dog. Then we use that information to create their dog's unique recipe – so their dog gets exactly the nutrition they need, in the taste they love, delivered to their door every month. It's clever stuff.

We are a fast-growing scale-up company, transitioning from our start-up roots and entering an exciting phase of rapid growth. As we evolve, we are focused on building a modern, scalable, and secure architecture that will support our ambitious plans for the future.

We've got bold plans. Having created an entirely new category in pet food, we're now scaling fast – backed by Purina, one of the world's largest pet food companies. You'll join a bunch of smart people working towards the same goals – and a bunch of smart-ish dogs, all working on their own thing.

Together, we'll change the world of pet food for good.
