[Hiring] Music & Sound Annotation Expert @Xperteez Technology

Role Description

In this role, 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.

• 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 details.
• Compare paired recordings of the same song captured at different locations and judge what stayed the same and what changed.
• In later phases: review AI model descriptions of clips and mark what's correct, wrong, or invented, with a brief written explanation.
• Attend a paid onboarding/calibration session and a short weekly sync.

Qualifications

• Working or gigging musicians, session players, producers, or mixing engineers.
• Music educators, ear-training instructors, band/choir directors, conservatory students or graduates.
• Location sound recordists, sound designers, foley artists, or podcast/documentary audio editors.

Requirements

• 3+ years of hands-on music or audio experience.
• Strong analytical listening: you can pick individual instruments out of a busy, noisy, real-world mix — not just studio recordings.
• Can identify tempo (within a few BPM) and musical key (relative pitch with a reference is fine).
• Comfortable with detail-oriented, repetitive annotation work in a web platform — dropdowns, timestamps, short structured notes.
• Clear written English for brief, evidence-based notes (e.g., "accordion enters around 0:12").
• Quality headphones, quiet workspace, reliable internet.
• Available 20–25 hrs/week for the engagement window.
