Every week we move millions of products to our customers at record speeds. Brilliant customer experiences at this kind of pace, require fresh and appealing products to be available whenever and however our customers shop with us. And in this area of our business, we help to make sure that happens.

By engineering innovative, smart technology, we put the tools in our colleagues’ hands to power a global supply chain. Whether it’s wine from New Zealand or milk from the local dairy farm – our tech performs. We solve problems at scale. We process billions of records, predicting and planning to make our customers lives easier. We keep our warehouses and stores operating smoothly around the clock, because what’s important to our customers is important to us.

As an Engineer (SDET), you’ll be working on products that constitute the backbone of the next generation Sainsbury’s Tech commercial platform. You’ll be pivotal in supporting the QA activities and driving test automation and quality standards for applications and systems used by both Sainsbury’s colleagues and customers.

We’d also like you to be yourself – analytical, curious and unafraid to learn new skills or challenge the status quo. You’ll constantly strive to improve the way things are done in your team, contributing as a progressive member of the engineering community.

Typical Technologies in our stack:

TypeScript, React, Node, NestJS, Docker, Kafka, Redis, PostgreSQL & MongoDB on an event driven micro services architecture running on AWS, deploying with Jenkins for CI/CD

We keep track of everything using Git, Jira & Confluence, and monitor with Kibana, DataDog, etc.

• Research, recommend and implement tools as needed with the goal of increasing automation
• Mentor team members on automation
• Define and implement a robust test charters, approach and plans
• Use appropriate measures and KPIs to validate and report on software quality and improvements
• Be a creative thinker who can quickly identify and test for functional ‘edge cases’ outside of expected functionality workflow (e.g. understand how the software works and how to break it)
• Support and review unit testing activities, pairing with engineers to ensure adequate coverage
• Implement automated e2e testing and sophisticated UI testing, for example using frameworks such as Cypress to write and maintain e2e test code.
• Integration testing of APIs and end to end integration architectures
• Performance and scalability testing
• Supporting in security / penetration testing

More about you:

• Thorough understanding of SDLC, specifically automated QA processes in agile development environments
• Strong working knowledge of testing fundamentals such as TDD & BDD
• Exposure and solid understanding in testing microservice architectures
• Strong programming skills and understanding of test frameworks, specifically within JavaScript but other experiences a plus
• Exposure to generic test automation frameworks for acceptance testing and acceptance test-driven development, e.g. Webdriver IO, Cypress, Selenium
• Exposure to common CI/CD tooling
• Exposure to Consumer driven contract testing
• Confident using Git
• Confident building test infrastructures using containerisation technologies such as Docker and working within continuous delivery/continuous release pipeline processes
• Confident testing enterprise applications deployed to cloud environments.
• Cross browser testing.
• Confident with common RDBMS and NoSQL offerings e.g. PostgreSQL, Redis
• Drive for advocacy of agile/lean delivery methodologies 

As well as lots of on-the-job training and endless opportunities, you’ll get:
