Java Developer

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.
We don’t think we’re exaggerating when we say we have the most exciting data set in the 
country. 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.
