Senior Data Scientist / Machine Learning Engineer

BarkBox, New York, NY

A monthly box of dog goodies


BARK is a company building products, experiences, and entertainment for dogs and the people who love them. The lasting brand that Disney has built for kids and families, BARK is building for the fast-growing market of dog people.

Our ambition-level is high, the opportunity is huge, and our love for dogs is through the roof! We launched in 2011 with BarkBox, a monthly themed subscription of all-natural treats and clever toys. Since then, we've shipped more than 50 million toys and treats to the dogs across the world and use all of that direct customer feedback to inform new initiatives and ways to make dogs happier.

But what kind of company is BARK? It's a company that has gone to the dogs. We are committed to a culture that is open, inclusive, generous, and enthusiastic — just like our pups. United by this dog-obsession, we embrace diversity of all stripes and spots. If your camera roll is 90% pictures of your dog, you belong here.

At BARK, we know that dogs aren't pets; they're family. Our people – crazy dog people – believe that their dogs deserve the best. The best treats, the best toys, the best seat on the couch. Together, we're driven to be the people our dogs think we are.


Can you give a pup belly scratches until you get carpal tunnel? Listen to squeaky toys until your ears bleed? BARK is a fast-growing business for people who love, (*ruv) dogs.
