About us

Appnovation is a global, full-service digital partner that combines Strategy, Experience & Design, Engineering and Managed Services. We build digital solutions that deliver real impact today and serve as foundations for future growth. Bold ambition. Practical action. Endless possibilities.

About the Role

Appnovation is seeking an experienced and detail-oriented Senior QA Engineer with strong technical testing skills and hands‑on experience validating modern React applications and headless CMS implementations, preferably Builder.IO, although Contentful or Sanity experience would also be relevant. This is an opportunity to ensure quality across a global project within our agile, cross‑functional teams. The intention is for the role to be a mixture of hands‑on manual and automated testing.

The Essentials

A strong mix of the following skills will make you an excellent candidate :

• 5+ years of relevant experience in software quality assurance, focused on web applications.
• Experience testing headless CMS implementations (Builder.io, Contentful, Sanity or similar).
• Multi‑lingual testing experience including English and non‑English languages.
• Experience testing modern React applications, including understanding of component‑based architecture, state management, and client‑side rendering behaviour.
• Experience with component library testing, preferably Storybook.
• Hands‑on experience with end‑to‑end & integration TS / JS test automation frameworks, preferably Playwright, although Cypress experience can also be considered. You should be able to independently write, maintain & extend automated test suites with minimal supervision, with a focus on “shift‑left” automation, starting with component library tests first.
• Experience with and understanding of Git for branching and version control, including integrating automated tests into CI / CD pipelines as appropriate.
• Automated visual regression testing experience using tools like Percy (preferable), Chromatic, or BackstopJS.
• Experience using AI and LLMs to expedite the creation of test scenarios, both manual and automated.
• Solid understanding of accessibility testing practices (WCAG 2.2) and experience using tools like Axe, WAVE, or Lighthouse to automatically identify compliance issues.
• Experience validating responsive designs across devices and breakpoints, including testing on real devices on iOS and Android platforms.
• Experience with page performance testing, using tools such as Google Lighthouse to validate against Core Web Vitals metrics.
• Experience working in Agile environments with short sprint cycles, participating in refinement, and providing accurate test effort estimates.
• Strong communicator, proactive, able to prioritise workloads and make recommendations.
