If you've ever stepped through the doors of a John Lewis or Waitrose shop, shopped online, or seen any of our adverts, you'll know there's something unique about us.

That unique proposition is our Partners. As co-owners they have a say in our business and receive a share of the profits, so they put time and effort into making it work. Our Partners are the reason we're the success we are. They're our secret sauce; the opportunity for us to differentiate.

Find out more about being a Software Engineer in the Partnership, and the technology we use.


What you’ll be doing?

You will also use your knowledge of quality engineering to support the shaping of new projects and support the professional development of less experienced software engineers. You will work with a diverse range of technical and non-technical stakeholders which will require excellent communication skills.


Learning new skills is extremely important to us. Engineers are expected to continuously improve their skills and keep abreast of the latest technologies and techniques regardless of their experience or job grade. In return for this commitment you will be given the resources and support you need to help you with your learning journey. 


What you’ll already have:

  • Knowledge of architectural patterns used to build modern web and mobile applications.

  • Practical experience of Continuous Integration/Continuous Delivery.

  • Coaching teams in use of continuous testing and shift left/shift right approaches.

  • Thinking critically about engineering approaches, using questioning techniques to lead team discussions about quality risks and appropriate responses.

  • Leading elaboration activities (such as three amigos sessions) to ensure specificity, consistency and testability.

  • Reading and writing coded solutions for a variety of engineering needs:

    • pairing with developers to understand and jointly enhance unit, functional and other coded tests

    • developing testing utilities

    • developing and maintaining code in pipelines

    • creating and maintaining coded checks such as API or GUI checks.

  • Working Knowledge of modern testing tools and frameworks for testing front end, API and / or mobile apps. 

  • Senior practitioner experience in one or more testing specialisms (e.g. native app testing, performance testing, security testing, React front-end testing, API testing).

  • Analysing performance risks (speed, volume, load, etc) and advising on how these risks should be mitigated.

  • Understanding operational requirements (such as resilience and observability) and how solutions are implemented and tested.


What else could you bring:

  • Experience of cloud infrastructure such as GCP and AWS.

  • Experience of testing tools such as Cypress, Codecept, Jest, Sitespeed, Gatling, Karate, Pact, XCTest and XCUITest) and ability to advise on the pros and cons of specific tools for varying scenarios.

  • Understanding of security threats and experience of automated security testing


Where will you be working?

We have opportunities at both our John Lewis Head Office in London Victoria, and Waitrose Head Office in Bracknell. Whilst you will have an office base - we promote a blended approach to working location. In order to maximise the benefits of remote and team working, you will be able to work from either our offices or from a remote location (as long as it is within the UK).  


We'll expect flexibility and will on occasions require you to be in the office. But for this role, it would be reasonable to plan on the basis of a 60/40 remote/office split.  In practice, we aim to maximise flexibility and these decisions will mostly be made locally within your team.


What benefits do we offer you?

We believe in rewarding our Partners for their time and energy. Find out about the benefits of working for the Partnership
