Java Engineer

Job description

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.

As a Java Engineer, you’ll be within one of the customer order fulfilment teams, creating great products by interpreting and utilising best practice architectural and engineering principles, operating frameworks, and new and improved tech applications and solutions.  

More about the role 

• Using Java 17+ with tools and frameworks like Spring Boot and AWS, you’ll own the design and development of large-scale, high-performance services running on AWS infrastructure, which includes websites, apps, microservices and event driven architecture.   
• As an engineer within a long lived, cross functional, autonomous team, you’ll work within a DevOps culture and own the entire stack from infrastructure to application, development to support and inception to retirement. 
• We’d also like you to be yourself – analytical, curious and unafraid to learn new skills or challenge the status quo. Through a culture of continuous improvement, learning and personal development you’ll improve the way things are done in your team, contributing as a progressive member of the engineering community.  

More about you

• Strong experience with design and development of large-scale high performance microservices using Java 17+ with tools and frameworks like Spring Boot 3. This includes websites, apps, microservices and event driven architecture. 
• Preferable experience working with cloud and container technologies such as Kubernetes on AWS, using Terraform and Docker. 
• Have experience deploying to production multiple times a day in small, iterative batches, using tooling like Jenkins and GitHub actions. 
• You’ll be empowered to influence and experiment with the ways of working that best suit the overall team and product. The teams currently use a mixture of Kanban/Scrum, pairing, mobbing and asynchronous working. 
• Supporting our ‘we build we own it’ culture where we are all responsible for the stability and security of the products we deliver. 

Whilst we are looking for these skills, we recognise our engineers have different depths of experience, so we support their learning through a minimum of 2 days per month dedicated learning time in addition to mentoring and coaching throughout the delivery of your work. 

Benefits

• Colleague discount across our multi-brands – Sainsbury’s, Argos and Habitat
• Holiday allowance
• Bonus scheme
• Pension plan
• Flexible / Smarter working policy
• Special offers on gym memberships, restaurants, holidays, retail vouchers and more

Work-life balance is important to us, so we offer our colleagues as much flexibility as possible in line with the needs of their role. We trust them to decide how, where and when they work, combining remote and collaborative working with a flexible approach to hours, giving them plenty of time and space for life outside of work whilst delivering against our business goals.
