DESCRIPTION
Overview
Welo Data is looking for detail-oriented and reliable individuals to join our team as Data Labeling Analysts, supporting speech and voice AI systems.

We’re looking for people who are dependable, focused, and take pride in producing high-quality work, even across repetitive workflows.
