  • Design, implement, and maintain automated testing frameworks across web, API, and mobile platforms using tools such as Cypress, Playwright, Cucumber, and Postman.
  • Drive effective testing strategies that balance unit, integration, API, end-to-end, accessibility, and exploratory testing.
  • Partner with Engineers, Product Managers, and Designers to identify risks early, improve testability, and ensure quality is considered during solution design.
  • Coach and mentor engineers on quality engineering best practices, automation, and effective testing approaches.
  • Drive continuous improvement of quality standards, tooling, and processes.
  • Advise on best practices for embedding automated testing and quality gates into CI/CD pipelines.
  • Foster a culture of shared ownership for quality by enabling teams to build, test, and release software with confidence.
  • Support and guide non-functional testing practices, including performance, security, and accessibility testing.

  • Extensive experience implementing shift-left and quality assistance testing methodologies within agile product development environments.
  • Strong expertise in quality engineering across frontend, backend, API, mobile, and end-to-end, including experience with Cypress, Playwright, Cucumber, Postman, and related tooling.
  • Experience working with CI/CD pipelines, Jenkins, Github and modern software delivery practices.
  • Strong understanding of software architecture, quality risks, and testability considerations.
  • Proven experience influencing engineering teams and coaching developers to adopt quality engineering best practices and shared ownership of quality.
  • Excellent communication, collaboration, stakeholder management, and organisational skills, with the ability to influence teams without direct authority.
