About the Tesco Technology - Forecasting team

In Demand forecasting, we build products that powers the engine of the Supply Chain that makes sure customers get what products they need when they walk into a Tesco Store or shop through other channels. We influence product availability through advanced forecasting and right ordering. It's challenging since it needs to be done whilst keeping waste reduction and optimal stock holding. This helps keep our operational costs in control and helps the bottom line. The more we save, the more we can pass on to our customers w.r.t the right price. It’s fun since we are building better capabilities on newer platforms.

This involves a lot of learning since we are transforming our forecasting intelligence to algorithms on big data platforms. We crunch a large volume of history, react to recent trends, promotional events, turn demands into the right kind of orders for supplier and store. The nature of our products lends itself to real-time data inputs, machine learning, and applied statistics, safely allowing us to say it’s a fantastic problem space to work in and help solve. We take responsibility for the software through its entire lifecycle. We practice continuous integration and delivery and support our code through to production and beyond.
