About the Role
Our client is looking for a Senior Test Automation Engineer to join its team of dedicated automation testers, working across a diverse range of agile projects within sectors including Health, Retail and Finance.
The Test Capability is passionate about “shift left testing”, ensuring testers are involved from day one. The team promotes a test-first approach, including TDD, to identify and resolve issues early and help deliver higher-quality solutions for clients.
The business is also embracing AI to accelerate and improve the way it works, while applying technical expertise and professional judgement to ensure consistently high-quality outcomes.
If you’re passionate about championing better testing — whether through new tools, technologies or ways of working — we’d love to hear from you.
What You’ll Bring
- Experience designing bespoke Test Strategies to complement technical solutions implemented using cloud technologies such as Kubernetes and Docker.
- Experience building frontend automation frameworks using modern open-source test automation tools such as Cypress and Playwright.
- Experience building backend automation frameworks using tools such as:
- HttpClient, RestSharp or RestAssured (C#)
- RestAssured (Java)
- SuperTest or Jest (JavaScript)
- Experience working in an Agile (Scrum/Kanban) project environment and applying a test-first approach to create a shared understanding of requirements, including Shift Left, Example Mapping, BDD and 3 Amigos.
- Experience implementing automated quality checks as part of a Continuous Integration environment, using platforms such as GitHub, Azure DevOps or AWS Pipelines.
- An enthusiasm for leveraging AI technologies to enhance your workflow, accelerate delivery and improve outcomes.

It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
