About us

Tesco is a leading multinational retailer, with more than colleagues.  Our software is used by millions of people across several countries every day.

Whether it's the tills and websites our customers use, or the systems our colleagues and partners use, you'll play your part in keeping it running like a well-oiled machine.

And when a business problem pops up? You and the creative minds in our team will be challenged to solve it.  As Tech Hub we cooperate within the group of Tesco Technology Hubs located in the UK, Poland, Hungary, Czech Republic and India.

What our colleagues like the most at Tesco:
  

We develop our own products
We make an impact; large scale of operation
Accountability and respect are given to us
We cooperate and support each other
There are great colleagues who are divided into small teams here
We can develop and learn new things

About the role
The Product Intelligence Platform is an AI-driven system that revolutionizes how Tesco handles product data at scale.

The platform leverages multi-agent AI systems to automate product categorization, enrichment, and matching across a vast number of products on a weekly basis.

Built on event-driven architecture using Kafka, the platform processes millions of events monthly through core AI capabilities.

A Senior Software Engineer in this team will be responsible for building and maintaining these AI-powered capabilities using Java/Spring Boot and Python, implementing scalable event-driven microservices on Azure Kubernetes Service, and working directly with LLMs to solve complex product intelligence challenges.

The role requires someone who can bridge the gap between cutting-edge AI technology, engineering, and practical business applications, contributing to a platform that directly impacts millions of customer interactions weekly.
