Music And Sound Annotation Expert

You will support audio-focused AI training by listening closely to short field recordings and documenting what you hear. The work includes structured annotation, music analysis, comparison of recordings, and quality review of AI-generated descriptions.

You will use quality headphones in a quiet workspace and provide concise, evidence-based notes. A paid onboarding and calibration session and a short weekly sync are also part of the role.
