Detect, investigate, and mitigate fraud across merchant acquiring products. Monitor transaction activity, support merchant onboarding/underwriting, manage disputes/chargebacks, liaise with card schemes and partners, and implement controls to meet regulatory and scheme requirements.
We believe that businesses of all sizes deserve better financial and payment products and services. Traditionally, businesses of all sizes are let down by slow applications, protracted onboarding, opaque pricing, restrictive contracts and forced to use outdated solutions that no longer meet the innovative requirements of modern business.
We started our journey four years ago, and have since helped tens of thousands of Australian businesses reduce the complexity and time taken to take and make payments, manage complex fleets of payment hardware, store and save money and lead the conversation in business-to-business fintech. We’re now taking our next steps in expanding our industry and world leading capabilities into the United Kingdom.
Our company is backed by leading global VCs, and brings together experienced payment and tech industry professionals who are aiming to redefine business banking and the way businesses get paid by their customers.
If you are passionate, curious, hungry and seeking an opportunity to make your mark on Fintech in the United Kingdom, with the strength of a global team behind you - we’d love to talk to you. This is a unique opportunity to shape, direct and build better financial services for all UK businesses.
