The Role

While you’ll have heard our name, there’s a lot you probably don’t know about NEXT. Like how we create most of our systems ourselves – whether it’s a website, mobile app or application. What’s more, we’re growing. Fast. And it’s the kind of growth and investment that is exciting for everyone in our business.
