mx51 is a payments-as-a-service solution for banks, non-bank acquirers, and other merchant service providers. We are building a payment platform that allows merchants to accept payments in-store, in-app and online, whilst consolidating all their data on a real-time business management dashboard. mx51 powers payment experiences for some of Australia's largest banks and acquirers.

As our platform matures and our tenant relationships deepen, we're looking for a Product Manager to be the voice of our products to the tenants who depend on them every day.
