We'd all like amazing work to do, and real work-life balance. That's waiting for you at Sainsbury's. Think about the scale it takes for us to feed the nation. The level of data, transactions, and variety it involves. Then you'll realise that ours is a modern software engineering environment because it has to be. We've made serious investment into a Tech Academy and into setting standards and principles. We iterate, learn, experiment, and push ways of working such as Agile, Scrum, and XP. So you can look forward to awesome opportunities in everything from AI to reusable tech.

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.

From the insights gained, we build scalable, high-performance products using cutting-edge technology that give our customers an amazing shopping experience - 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.
