Job Description
ABOUT QUANTUMLOOPAI QuantumLoopAI is one of the UK's fastest-growing healthtech companies. Our AI-powered platform, EMMA, is used by hundreds of organisations across the UK to manage communications, automate workflows and deliver better outcomes through intelligent automation. Backed by leading investors and scaling rapidly ahead of our Series A, we are building the infrastructure that will define the next generation of AI-driven service delivery. ABOUT THE ROLE Our platform handles real, live conversations — and because those conversations matter, quality is critical. Small errors have real consequences. We are looking for a QA Automation Engineer to own and grow the automated testing that keeps our voice AI platform reliable. You will build and maintain automated test coverage across backend and frontend, create automation that places and validates real test calls end to end, and measure the accuracy of the speech-to-text (STT) and text-to-speech (TTS) layers that make the platform work. This is a hands-on, high-ownership role where your testing directly protects real users. WHAT YOU WILL DO Backend and Frontend Test Automation Build and maintain automated test coverage across backend services and the frontend, ensuring new features ship without breaking existing behaviour. Integrate tests into CI pipelines so quality checks run automatically on every change. Work with engineers to turn real-world failures into permanent regression tests. Voice Pipeline and Call Automation Build and run outbound-call automation that places test calls through the live voice pipeline, simulates realistic caller scenarios, and validates the platform's behaviour from start to finish. Test the speech-to-text (STT) layer — measuring transcription accuracy and how reliably the platform understands callers. Test the text-to-speech (TTS) layer — validating pronunciation, naturalness, and that the voice output behaves correctly. Run regression testing across multiple conversation flows and
