What is Slice?

Pizza is at the heart of our communities. From birthday parties to gameday potlucks, life’s special moments are bettered by the craftsmanship and tradition found behind local pizzerias’ counters. We’re here to make sure these iconic small businesses serve our communities for generations to come by giving them the digital tools and services commonly found at big chains. Can you imagine what a small mom and pop pizza shop could achieve with the resources of Domino’s? 

Slice, Belfast is one of the company’s busy technology hubs and home to many of our Software specialists, Designers, Product and People Teams. We have a world class office and an office culture that is second to none, so we hire the best!   

Yes, we have a pizza philosophy

Across the country, pizza is made by people who care about craft, history, and culture. We created Slice to champion the small pizzerias by connecting those proud makers with customers who are just as passionate about their pizza. We celebrate pizza as the ultimate shareable food that brings people together for more than just a bite.

We’re growing our team every day — so, if you’ve got a passion for local, authentic pizza and the drive to help share it with the world, we’d love to have you on the team!
