- Assess the current NFT/performance testing approach and advise whether it is fit for purpose
- Recommend alternative approaches, tooling or improvements where required
- Design, write and maintain E2E regression tests using Playwright and TypeScript
- Monitor, maintain and improve automated test pipelines within Azure DevOps
- Produce clear test reporting to support release readiness and feature sign-off
- Work closely with developers, manual testers, QA leadership and client stakeholders to identify, triage and resolve defects
Required Experience
- Strong hands-on experience with k6 for performance testing
- Proven experience owning or leading non-functional testing within a project or workstream
- Strong Playwright and TypeScript experience for E2E automation
- Experience working in BDD/TDD environments, ideally with Cucumber
- Good understanding of automation-first delivery and test pipeline automation
- Experience working with Azure DevOps pipelines
- Consultancy background or experience working in client-facing delivery environments
- Comfortable operating independently, managing your own workload and communicating clearly with senior stakeholders
