## Description

We're looking for a QA Automation Engineer who writes code, not just test cases. You'll build automated tests in C# on our in-house .NET test framework, write behaviour-driven development (BDD) scenarios in Gherkin, and work inside the codebase alongside developers on unit tests as well as end-to-end coverage.

You'll own quality across the whole test pyramid, from unit level up to the user interface, so defects are caught long before they reach our customers.

What you'll do

 * Write and maintain automated tests in C# using our custom .NET test framework
 * Write unit tests alongside developers, not only end-to-end tests
 * Turn requirements into behaviour-driven scenarios in Gherkin and automate them with Cucumber
 * Build and run automated user interface, API and functional tests for our web applications
 * Plan test strategy with development and product teams, and design test plans and cases
 * Maintain and improve our continuous integration (CI) pipelines so tests run reliably on every change
 * Investigate failures, troubleshoot issues in systems under test, and work with developers on fixes
 * Document test results and defects clearly
 * Run post-release testing
 * Use AI tools to speed up your work and improve code and documentation, while critically reviewing what they produce
