We’re a multi-channel, multi-brand business serving millions of customers a day, with the UK’s largest loyalty scheme and an ever-evolving set of digital platforms. All of this equals over 1.2 billion transactions each year, presenting a volume, depth and complexity of data that few can match.

We don’t think we’re exaggerating when we say we have the most exciting data set in the country. And from the insights gained, we build scalable, high-performance products using cutting-edge technology that give our customers an amazing shopping experience â€“ like our award-winning Smartshop app. In an inclusive, agile environment, you’ll have the space to be curious, to experiment, and to solve real-world challenges. And you’ll get to see your creations in the hands of millions of people across the UK.

As an Engineer (Full Stack Javascript), you’ll be part of one of our Engineering squads, interpreting and following architectural and engineering principles, operating frameworks, and new and improved tech applications and solutions. With your technical craft, curiosity and experimentation, you’ll use judgement to apply specific techniques to deliver focused outcomes that support our customers.

We use a variety of tech here and you need to be willing to pick up new tools and techniques. We’d also like you to be yourself – analytical, curious and unafraid to challenge the status quo. You’ll constantly strive to improve the way things are done in your team, contributing as a progressive member of the engineering community.
