Customer Service & Support AI Rater & Evaluator

Overview

LILT is building a global network of domain experts to support high-quality AI evaluation across training, benchmarking, red-teaming, and ongoing model monitoring. We are seeking customer service and support professionals to contribute expert judgment to human-in-the-loop AI evaluation workflows used by leading enterprises and hyperscalers.

This role is designed for professionals who understand how customer support interactions work in real operational environments and who can apply that expertise to evaluate, assess, and improve multilingual AI systems used in customer-facing contexts.

Your contribution of expertise will directly influence multilingual AI model quality, safety, and deployment readiness.

This role includes two distinct expert tracks, based on experience level and scope of responsibility.

Responsibilities

• Validate and refine evaluation rubrics and edge-case handling

• Perform adjudication where raters disagree

• Conduct error analysis and qualitative reviews of model behavior

• Partner with LILT research, product, and customer teams on evaluation design

• Support red-teaming, policy alignment, and model readiness assessments

Ideal Background
