About the role
The payment services team is at the heart of Tesco Technology, serving over 28 million shoppers in the UK and abroad. We deliver HTTP services that reliably manage payments at global scale, 24 hours a day, every day. We also provide capabilities that detect and prevent fraud and build upon innovative technologies to reduce loss. We process 100M+ transactions and billions of events per day, a billion pounds every week.
At the core of our operation are the APIs that handle a variety of payment methods including cash, card and gift card across stores, at our fuel stations and online. We also support wallet behaviours, repeat payments, refunds and identity checks. They are built around an event sourcing architecture using Java, Akka, Cassandra, Postgres and Kafka. We embrace DevSecOps wherever possible. Automation is a key area of focus for us. Our scale and workloads demand that we continuously improve our approaches to testing and deployment. Kanban is the way we manage our work. We support what we code.
