Join Tesco's Personalisation team and help shape the experiences of millions of customers every day by powering real-time recommendations, offers, targeting, and experimentation across our web, mobile, and in-store channels.
Our platforms combine real-time data, machine learning, and large-scale distributed systems to turn customer insights into intelligent decisions in milliseconds. You'll work on complex engineering challenges spanning streaming data, low-latency decisioning services, and ML powered systems, while collaborating closely with product, data science, and analytics teams.

- Working with Kafka and event-driven architectures
- Building pipelines using Apache Flink and Apache Beam
- Integrating ML models and feature stores
