FUNCTION: Engineering

We're looking for a talented Senior Software Engineer to join our Cards team. Our goal is to build out a seamless card issuing and transaction platform that bridges crypto and fiat - enabling merchants to offer their customers instant access to funds through physical and virtual cards.

Traditional card programmes have often been rigid, slow to integrate, and limited in their ability to handle multi-currency flows across crypto and fiat rails. With our platform, we're breaking down these barriers by delivering a modern card infrastructure that handles everything from tokenization and sensitive card data to real-time transaction enrichment and settlement. This allows our merchants to offer card products that work fluidly across currencies, with the security, speed, and reliability their customers expect. By building this from the ground up, we're creating a best-in-class card experience that sits at the intersection of traditional payments and digital assets.

Our product and engineering organisation is split into small autonomous squads empowered to own their problem space. You'll be expected to form strong opinions and execute in a fast but sustainable way, advocating for the simplest solution that achieves the outcomes our customers are looking for.
