Senior QA Engineer (Foundational QA, HealthTech, EU-based)

About the project

Our client is a fast-growing German HealthTech startup building an AI voice assistant for nurses and care workers. Nurses speak into a mobile app, and the product automatically turns it into care documentation, saving them hours of admin work every week. The product is already used by thousands of care facilities across Europe and is expanding to the US.

About the role

This is a foundational QA role. There is no QA in the team yet, and you will be the first and only QA engineer working alongside 6 developers. We are looking for someone who doesn’t just execute test cases but truly understands the product, its users and the business logic behind every feature, and who can build a QA process from scratch.

Responsibilities

Become the go-to expert on product quality: learn the product deeply and understand how nurses use it in real life

Test new features and releases across mobile apps, APIs and integrations

Set up the QA process from scratch: test documentation, bug tracking, regression and release checks

Work closely with developers and product to clarify requirements and catch issues early

Define what should be automated and help lay the foundation for test automation
