About the role

The engineers in our Identity team build the APIs that securely identify customers across all touchpoints with Tesco around the globe: online, over the phone, and in-store with Clubcards. You’ll focus on making our experiences as streamlined for customers as possible, by exploring groundbreaking authentication factors like biometrics and using ML technologies to dynamically assess the risk of each individual customer session. Your work will be at the heart of all new propositions across the Tesco Group, like our new Clubcard Plus subscription service. All of this happens in a world where scale and resilience are critical – serving over a billion API calls every week in only a handful of milliseconds each!

The stack: Java, Kotlin, Cassandra, MySQL, Oracle, Azure, AWS, Apache Spark, and Kafka

We are responsible for the software throughout the lifecycle; we maintain a DevOps culture, employing continuous integration and delivery, supporting our code through to production and beyond, as well as being firm believers in TDD.

You will be responsible for

  • Using in-depth knowledge of at least one major programming language, the framework, and the tool ecosystem to implement end-to-end systems without assistance.
  • Translating requirements into tasks & code.
  • Producing test-driven features and demonstrating your familiarity with the TDD cycle.
  • Applying your understanding of cohesion and the SOLID principles to create well structured, maintainable software.
  • Working with product teams to communicate and translate needs into product improvements.
  • Supporting production systems, resolving incidents, and performing root cause analysis.
  • Sharing knowledge with the wider engineering community.
  • Producing proof of concepts to evaluate new tools.

You will need

  • 5+ years of experience as a Java backend developer. 
  • Experience with Java 8+.
  • Experience using SQL & NoSQL Databases.
  • Experience with cloud platforms (e.g. AWS/Azure).
  • Experience scaling systems. 
  • Experience working with multiple software development methodologies including Scrum & Kanban.
  • Experience with reactive programming is considered a plus.
  • Experience with eCommerce and search systems would be a nice to have, but not necessary.

About us

Our vision 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 our customers, communities and planet a little better every day”.  Serving means more than a transactional relationship with our customers.  It means acting as a responsible and sustainable business for all stakeholders, for the communities we are part of, and for the planet.

We are proud to have an inclusive culture at Tesco where everyone truly feels able to be themselves.  At Tesco, we not only celebrate diversity, but recognise the value and opportunity it brings.  We’re committed to creating a workplace where differences are valued, and make sure that all colleagues are given the same opportunities.  We’re a big business with diverse working patterns and many business areas which means that we can find something that works for you.  Everyone is welcome at Tesco.

We have recently announced that we are moving to a more blended working week – combining office and remote working.  Our offices continue to be where we connect, collaborate and innovate.  Talk to us about how this can work for you.
