About the vacancy

Our client is a leading international provider of online payment solutions, built on 100% proprietary technology. The platform is UK-based and currently processes 150+ currencies, offering access to all international cards and popular local payment methods to merchants through one integration. Customers in our portfolio include Samsung, Transferwise, Hopper, Virgin, Adidas and other top brands.

Client's mission is to partner with smart businesses to optimize their payments, increase revenue and meet the dynamic needs of their customers. Current project is the core of the journey for all merchants processing through the platform.
