Senior QA Engineer Location - UK South Becoming part of our team Own Quality. Enable Speed. Drive Better Engineering Practices. In the words of one of our senior clients recently… "Market Research has changed more in the last 3 years than the previous 40" We are looking for an experienced Senior QA Engineer to help strengthen quality across our products and platform while enabling faster and safer delivery. You will work within a Scrum team alongside developers, product owners and DevOps engineers, helping ensure quality is built into the development process rather than tested at the end. In our engineering model, developers own most automated testing, including unit, API, integration and performance tests. QA focuses on exploratory testing, risk analysis, end-to-end behaviour and ensuring the overall quality of our systems. This is a hands-on role for someone who enjoys working closely with developers and influencing how quality is approached within modern engineering teams. What you will be doing Working in a microservices-based .NET environment with CI/CD, you will help teams deliver software frequently and safely. Your responsibilities will include: • Working within Scrum teams to embed quality thinking early in the development lifecycle., • Supporting developers in building strong unit, API, integration and performance testing., • Promoting shift-left practices to detect issues earlier in development., • Performing exploratory, risk-based and end-to-end testing where automation alone is insufficient., • Identifying system risks, edge cases and integration issues early., • Contributing to improving test automation frameworks and CI/CD testing workflows., • Helping reduce flaky tests and improve confidence in automated pipelines., • Participating actively in refinement, planning and retrospectives, ensuring quality considerations are included. What success looks like Success in this role means teams are able to release software frequently and confidently, supported by reliable automation and strong engineering practices. You will help ensure that: • Developers take ownership of automated testing., • Defects are found early rather than late in the process., • QA effort focuses on risk and system behaviour, not repetitive manual testing., • Automated tests provide fast and trusted feedback in CI/CD pipelines. Quality discussions focus on risk, impact and outcomes, not simply test counts or pass rates. Technical background You should have experience working in Agile teams where quality is a shared engineering responsibility. We are particularly interested in candidates who understand shift-left testing and developer-led automation. Experience with the following is desirable: • Test automation in .NET / C# environments, • UI automation tools such as Selenium, • BDD frameworks such as Reqnroll, • Test frameworks such as NUnit, xUnit or MSTest, • API testing using REST, Postman or Swagger/OpenAPI, • CI/CD pipelines and automated testing workflows, • SQL and relational databases such as SQL Server or MySQL, • Cloud environments, ideally Microsoft Azure, • Microservices architectures Experience with Docker, contract testing, performance testing tools such as K6, or feature flag driven development would be beneficial. Collaboration and influence While this is not a people-management role, you will act as a senior quality voice within your team. You will: • Work closely with developers to improve testing practices., • Review and guide automated tests written by developers., • Share quality engineering practices with other QA engineers across teams. Why join us You’ll be joining a modern engineering environment built around CI/CD, microservices and cloud technologies, where quality is treated as an engineering responsibility rather than a final gate. This role offers the opportunity to work in teams where: • Developers actively participate in testing, • Automation is central to how we deliver software, • QA focuses on insight, risk and improving engineering practices If you enjoy working closely with developers, improving testing practices, and helping teams deliver high-quality software faster, this is a role where you can make a real impact.
