Job Description

### Overview

Welo Data is looking for sharp, curious, and detail-oriented individuals to join our team as Data Quality Analysts.

This is not a traditional annotation role.

You’ll be working directly with cutting-edge AI systems — evaluating outputs, identifying gaps, and helping improve how these systems behave in real-world scenarios. The work sits at the intersection of data quality, model evaluation, and human judgment, where your ability to think critically matters just as much as following guidelines.

We’re looking for people who are naturally curious about AI, comfortable forming opinions, and confident in contributing to conversations with teammates, leads, and stakeholders.

• Naturally curious about AI, technology, and how systems behave

• Comfortable speaking up, asking questions, and contributing ideas
