Data Quality Analyst

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.

Location: Washington

Hours: Full-time, 40 hours per week

Employment Type: W2 Full-Time Employee

Work Authorization: Must be authorized to work in the U.S. (no visa sponsorship)

Pay rate: $30/ hour

What You’ll Do

Evaluate AI model outputs and provide structured, high-quality feedback

Perform audit-based reviews of data and model behavior — identifying patterns, edge cases, and failure modes

Apply guidelines thoughtfully — and flag when they don’t reflect real-world scenarios

Contribute to improving evaluation frameworks, not just executing them

Identify trends in model performance and communicate insights clearly

Participate in team discussions, calibrations, and stakeholder syncs

Partner with leads and cross-functional teams to refine quality standards

Document findings in a clear, concise, and actionable way

What We’re Looking For

Native-level English proficiency and a university degree (Bachelor’s or higher)

Proficiency in languages other than English is preferred, with particular interest in candidates demonstrating bilingual mastery in French, Italian, German, Spanish, or Brazilian Portuguese.

1-2 years of professional writing experience with strong, structured writing skills

Ability to apply complex writing rules and guidelines consistently

Strong understanding of safety considerations in GenAI data delivery, with 2+ years of relevant experience

Strong critical thinking and attention to detail

Ability to make sound judgment calls in ambiguous situations

Naturally curious about AI, technology, and how systems behave

Comfortable speaking up, asking questions, and contributing ideas

Strong written and verbal communication skills

Ability to stay consistent while working with evolving guidelines

Experience in data quality, QA, annotation, or analysis is helpful — but not required
