Lead Data Scientist

New York, NY, Remote (East Coast) / Full-Time


Here at BARK, we love dogs and their people. We’re looking to make all dogs happy throughout the entire world (we’re not kidding). Think Disney for dogs -- we make magic for dogs and their people through our products, events, and experiences.

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 70 million toys and treats to dogs across the world and use all of that direct customer feedback to inform new initiatives and ways to make magic between dogs and their people. We’ve since expanded into other offerings as well, as we aim to become THE Dog Company for every family with a four-legged, belly-scratch-loving, interspecies family member.


Meet the Data, Analytics & Machine Learning (DAML) Team, a squad of professionals dedicated to transforming how BARK leverages data to create delightful experiences for dogs and their humans. Comprising data scientists, data engineers, and BI professionals, we're a close-knit family united by our passion for innovation, creativity, and, of course, our love for dogs.

Here's what sets us apart:

Innovation: We employ cutting-edge techniques to analyze and manipulate data, driving key business decisions and enhancing customer experiences.

Collaboration: Creativity meets collaboration in our team, where data-driven insights are paired with dog-driven enthusiasm.

Culture: We celebrate our unique quirks and talents, fostering a diverse, lively, and supportive environment where everyone has a voice.

This high visibility role offers an opportunity to join our dynamic squad, working hand-in-paw with partners throughout BARK to deliver science-driven improvements across the business. If you're someone who thrives in a diverse, lively, and supportive environment, you might just be the perfect fit to join our pack!
