About The Role

At Tesco, we believe in the power of spending more time together, face to face, than apart. So, during your working week, you can expect to spend 60% of your time in one of our office locations or local sites and the rest remotely. We also recognise that life looks a little different for each of us. Some people are at the start of their careers, some want the freedom to do the things they love. Others are going through life-changing moments like becoming a carer, nearing retirement, adapting to parenthood, or something else. That’s why at Tesco, we always welcome a conversation about flexible working. So, talk to us throughout your application about how we can support.

The payments service team are the heart of Tesco Technology, serving 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. 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.
