• Documenting and reporting test results, working closely with software developers to address any issues.

An ideal candidate is likely to be: 

• From a professional mobile app (preferably hybrid) testing background
• An advocate for Test Driven Development, comfortable writing automated end-to-end tests (preferably in JavaScript or TypeScript).
• Familiar with git-based workflows (pull requests, rebasing, etc.) and the principles of Continuous Integration (CI).
• Self-motivated, with a track record of improving test processes and coverage.
• A clear communicator, used to working in an Agile development team.
• Methodical and rigorous, with a logical approach to problem solving.
• Passionate and knowledgeable about music, audio technology, and recording.

Experience of some of the following would also be useful:
