Senior Software Development Engineer – Payments
About The Role
The payments service team is 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 to detect and prevent fraud and build upon innovative technologies to reduce loss. We process over 100 million transactions and billions of events per day, amounting to 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, fuel stations and online. We also support wallet behaviours, repeat payments, refunds and identity checks.
As a Senior Software Developer at Tesco, you will be responsible for the entire development and support process for a software programme. Your applications will make previously sophisticated tasks simple, saving time, effort or money, and redefining the norm. While the role focuses on day‑to‑day code writing, you’ll also lead on design and architecture, and help mentor and develop those around you.
If you enjoy working on high‑impact, business‑critical systems, this could be the team for you.
