Senior Software Engineer - Search & Recommendations

The engineers in our Search & Recommendations team build the APIs that ensure that the results of our customer searches on all of our platforms are accurate and relevant, and the work you can do in the domain will go beyond the usual duties of a backend engineer. Apart from being exposed to cutting edge cloud and server-side technologies, you will work closely with data science teams, applying models and algorithms to improve the engine behind the services, helping users to discover the products they really want - and all of this happening in a handful of milliseconds! This is a fantastic opportunity to work in a domain where small changes lifting the performance of the APIs have a huge impact, both for customers but also in terms of £millions of annualised revenue for Tesco.

Our vision here 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 Britain's shoppers a little better every day’. Our business was built with a simple mission – to be the champion for customers, helping them to enjoy a better quality of life and an easier way of living. This hasn't changed. Customers want great products at great value which they can buy easily and it's our job to deliver this in the right way for them. In the UK, we serve some 66 shoppers every second, so it's our goal to ensure every one of those customers experiences just a little better service on each visit.

At Tesco, inclusion means that Everyone’s Welcome. Everyone is treated fairly and with respect; by valuing individuality and uniqueness we create a sense of belonging.
Diversity and inclusion have always been at the heart of Tesco. It is embedded in our values: we treat people how they want to be treated. We always want our colleagues to feel they can be themselves at work and we are committed to helping them be at their best.

Across the Tesco Group we are building an inclusive workplace, a place to actively celebrate the cultures, personalities and preferences of our colleagues – who in turn help to build the success of our business and reflect the diversity of the communities we serve.
