Job summary

QuantumLoopAI is a UK healthtech company offering an AI-powered platform, EMMA, that handles real conversations. The QA Automation Engineer role owns and grows automated testing for our live voice AI platform, covering backend and frontend, API and UI layers, and end-to-end call validation.

The role emphasizes hands-on testing, regression coverage, and collaboration with engineers, with remote work aligned to UK business hours and opportunities for professional development.

Qualifications

• 4+ years of hands-on experience in QA automation or software testing with a strong automation focus.
• Strong hands-on Python — you write, debug and maintain test scripts daily.
• Experience writing and maintaining automated test suites across both API and UI layers.
• Comfortable testing REST APIs and working with structured data (JSON).
• Experience with automated web and UI testing frameworks.
• Familiarity with version-control workflows (Git) and continuous-integration pipelines — you have integrated automated tests into CI/CD.
• Solid grasp of QA methodology — test design, regression strategy, and the defect lifecycle.
• Excellent attention to detail and clear written communication.
• Comfortable working remotely and aligning to UK business hours (9:00 AM to 6:00 PM GMT/BST).

Responsibilities

• 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.
• 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 catch behavioural drift after changes.
• Evaluate calls against conversational quality dimensions — accuracy, tone, flow adherence, understanding, hand‑off between stages, summaries, outcome handling, call control, and avoiding unnecessary repetition.
• Reproduce, document, and track defects through to resolution, writing clear reproduction steps from real call examples.
• Work with engineers, prompt authors, and the operations team to identify quality issues and build permanent test coverage around them.
