The Role
We're looking for a QA Engineer with strong manual testing experience and an eye for detail to help ensure the quality of our software releases. Working closely with our Development, Product and Technical teams, you'll play a key role in testing new functionality, identifying defects and helping us deliver reliable, high-quality software to our customers. Whilst the role is primarily focused on manual testing, any exposure to test automation would be advantageous and you'll have the opportunity to develop these skills over time.
