The Role:As a Senior Test Engineer, you'll become a key member of a small, agile delivery team working on a live, high-profile project.

- Designing and implementing automated testing solutions across UI, API and system levels.
- Embedding continuous testing within modern CI/CD pipelines.
- Combining automated and exploratory testing approaches to deliver high-quality software.
- Working within Agile environments and applying modern engineering practices including TDD, BDD and ATDD.
- Building and maintaining scalable automated test frameworks.
- Supporting non-functional testing activities such as performance, security, accessibility and operational acceptance testing.
- Helping shape testing strategy, frameworks and best practices across the wider QA community.

- Selenium
- Playwright
- Cypress
- Webdriver.io

- Robot Framework
- Serenity BDD

We're seeking passionate, curious and motivated Test Engineers who enjoy tackling complex challenges and continuously developing their skills. Most importantly, we're looking for people who enjoy solving problems, sharing ideas and helping teams build great software.

- Strong experience in both manual and automated testing.
- Experience designing and implementing automated test frameworks.
- A quality-first mindset with a passion for improving engineering standards.
- Experience working within Agile delivery environments.
- Strong collaboration and communication skills.
- The ability to work independently while contributing to a high-performing team.
