Music Audio Expert - Spanish (ES) | $8.57-$9.86 One-Time Remote
Overview
Mercor is teaming up with a leading AI lab to find seasoned music pros who can judge how well generative AI models create and interpret music. In this fully remote, task-based gig, you'll evaluate Spanish-language tracks across a wide range of genres, scoring them on musicality, creativity, prompt adherence, vocal quality, and production polish. Your feedback will directly shape how these AI systems learn and improve. What really sets this role apart is its dual-language focus — you'll work in both Spanish and English using a structured taxonomy that breaks down genres, song structure, and vocal/instrumental details. It's a flexible, part-time commitment of 10+ hours per week that runs for up to six months.
What You'll Do5
- 1Compare AI-generated music tracks side by side and rate them on musicality, creativity, prompt adherence, vocal quality, and production/mix quality.
- 2Classify each song using a detailed taxonomy, covering genre and sub-genre, song structure, and vocal and instrumental characteristics.
- 3Review generated lyrics and vocal performances against reference material, assessing accuracy and overall quality.
- 4Score the quality of musical training data used to build the AI models.
- 5Work in both Spanish and English to capture the nuances of Spain's Spanish-language music landscape.
Requirements4
- 1Native or near-native fluency in Spanish, with the ability to follow detailed written instructions in English.
- 2Professional or semi-professional music experience — either on the production track (3+ years as a music producer, audio engineer, or sound mixer with a strong ear for describing mixes) or on the music & language track (deep knowledge of Spain's Spanish-language music scene, plus experience as a songwriter, lyricist, performer, composer, or music journalist).
- 3Access to headphones or studio monitors suitable for careful, critical listening.
- 4Nice to have: formal training in music theory, performance, or composition, and broad familiarity with contemporary Spanish-language genres, sub-genres, and artists.
Who Should Apply
This role is perfect for a music professional who loves listening critically and is genuinely curious about how AI is transforming creative work. You're comfortable working independently, following structured rubrics, and knocking out a handful of evaluations each week. Whether your background is in the studio or on the stage, you have a sharp ear for what makes a Spanish-language song connect — and you're excited to channel that expertise into evaluating cutting-edge generative music models.
Salary Insight
Pay is per completed task rather than per hour. The $8.57–$9.86 range shown is a blended average across task types — shorter tasks pay less individually, while longer ones pay considerably more. Completing more tasks each week also moves you into a higher rate band.

Application Tip
Before applying, do a quick practice run: listen to a few AI-generated Spanish-language tracks and jot down notes on musicality, prompt adherence, and production quality. Bring those notes to your conversational interview — it shows you've already engaged with the core workflow and can speak fluently about the evaluation criteria.
