Music Audio Expert - English (UK/Australia)

Mercor is hiring experienced music professionals to evaluate generative music AI models, in partnership with a leading AI lab.

You will assess AI-generated music across a wide range of genres and rate it against detailed quality standards, working in English.

Key Responsibilities

• Rate AI-generated music samples head-to-head on musicality, creativity, prompt adherence, vocal quality, and production/mix quality
• Annotate songs in detail: genre and sub-genre classification, song structure, and vocal and instrumental characteristics, using a structured taxonomy
• Evaluate generated lyrics and vocal performance against reference material
• Score the quality of musical training data

Requirements

• Native or near-native proficiency in English, including strong professional written English
• Professional or semi-professional experience in music, via either track below
• Headphones or studio monitors suitable for careful listening

We hire on either of two tracks

Production track — 3+ years working as a music producer, audio engineer, or sound mixer, and comfort using audio-engineering vocabulary to describe a mix by ear.

Music and language track — deep knowledge of the UK and Australian English-language music scene, with professional or semi-professional experience as a songwriter, lyricist, performer, composer, or music journalist. Studio production credentials are not required on this track.

Nice to have

• Formal training in music performance, theory, or composition
• Experience writing, performing, or producing released music in English
• Broad familiarity with contemporary UK and Australian English-language genres, sub-genres, and artists
