Medior / Senior Test Engineer

We are looking for a tester with a clear approach and critical eye when it comes to our software. You will be responsible for the design and execution of test plans. In addition, you take ownership of continuously improving our testing approach, with a strong focus on test automation and smarter, more efficient workflows. Key about your role As a Software Tester within a Scrum team, you help the team deliver reliable software that is fit for customer use. You define and apply an effective test approach for epics and stories based on their risks and impact. Together with software engineers, business analysts and the Product Owner, you make quality an explicit consideration from refinement through release. You design, review and execute manual and automated tests (We use Playwright). You assess test coverage across the relevant testing levels and consider integration, performance and security testing when appropriate. You identify edge cases early, challenge assumptions in requirements and solution designs, and translate test results into clear, actionable quality information. When defects or test failures occur, you ensure they are clearly documented, analysed and followed up. You help determine whether the right response is a test fix, a product fix or explicit risk acceptance. For larger epics and cross-team work, you maintain oversight of the overall test effort and guide colleagues who contribute to it. We also embrace AI-assisted testing as part of our development lifecycle. Our engineers use tools such as Claude, ChatGPT and Codex to explore requirements and risks, develop test scenarios, support test automation, analyse failures and document findings. AI is an aid, not a substitute for professional judgement. You are expected to understand and validate its output and remain accountable for the quality, security and correctness of your work. As part of a community of fellow testers, you keep developing your knowledge of testing techniques, tools, automation and the insurance domain. You share what you learn, contribute to testing standards and help the team treat quality as a shared responsibility. Key About Your Team The Axon Product Development department consists of more than 120 colleagues, organised across 9 functional clusters such as Claims, Contracts, Financials and Requests, and 16 Scrum teams.
