Your work will be at the heart of all new propositions across the Tesco Group, like our new Clubcard Plus subscription service. All of this happens in a world where scale and resilience are critical – serving over a billion API calls every week in only a handful of milliseconds each!

The stack: Java, Kotlin, Cassandra, MySQL, Oracle, Azure, AWS, Apache Spark, and Kafka

About us

Our vision at Tesco is to become every customer’s favourite way to shop, whether they are at home or out on the move.  Our core purpose is “Serving our customers, communities and planet a little better every day”.  Serving means more than a transactional relationship with our customers.  It means acting as a responsible and sustainable business for all stakeholders, for the communities we are part of, and for the planet.
