Role Title: Music & Sound Annotation Expert
Role Type: Contractor
Location: Remote
We are engaging Music & Sound Annotation Experts to contribute to a customer's project at the forefront of music and audio technology.
Your ears are the ground truth. You'll listen to short field recordings and document exactly what's audible — instruments, tempo, key, background sounds, crowd reactions — through a structured web platform built for this project. Later phases involve grading AI model answers against what you actually heard.
What you'll do
Listen to 30–90 second field recordings (headphones, your own quiet workspace) and complete structured annotations: which instruments are present, tempo and key, timestamps of background events (traffic, sirens, applause), scene detailsCompare paired recordings of the same song captured at different locations and judge what stayed the same and what changedIn later phases: review AI model descriptions of clips and mark what's correct, wrong, or invented, with a brief written explanationAttend a paid onboarding/calibration session and a short weekly syncWho we're looking for (any of these backgrounds)
