Job description

Overview

Join the team behind Price Service—a mission-critical HTTP API powering pricing and promotions across all of Tesco’s channels. From tills to websites and everything in between, our work touches the lives of over 28 million UK shoppers every week, with global reach on the horizon.

We’re building a robust, internet-facing API that runs both in stores and in the cloud, designed to support future innovation at scale. This means solving complex distributed systems challenges, ensuring high availability, and optimizing performance. Concepts like the CAP theorem aren’t just theory here—they’re part of our daily engineering conversations.

Our stack includes Java, Vert.x, RxJava, Groovy, Couchbase, and Kafka, running on Azure with a fully automated CI/CD pipeline. We follow Agile principles, adapting Kanban and other methodologies to fit the team’s needs. Collaboration is at the heart of our culture—pair programming is common, and all code is reviewed via GitHub.
