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.

Apply domain-specific customer support guidelines consistently across tasks
Ideal Background
Customer support professionals, service operations specialists, or CX practitioners
Experience handling customer inquiries, support workflows, or service escalation
Strong attention to detail and comfort working with structured evaluation criteria
Evaluators provide higher-level domain oversight and help shape how evaluation is performed.
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
Senior support leaders, CX managers, or service quality specialists
Experience defining support standards, reviewing complex edge cases, or managing escalations
Ability to clearly explain nuanced service decisions and tradeoffs
Types of AI Evaluation Work
Depending on project demands, work may include:
Customer service and support content evaluation
Tone, empathy, and response quality assessment
Policy adherence and escalation handling evaluation
Red-teaming for harmful, unsafe, or misleading responses
Ongoing model monitoring and regression testing

Comfort working with structured evaluation workflows
Ability to explain reasoning clearly, especially in sensitive customer scenarios
Reliability, professionalism, and respect for quality standards

Why This Work Matters
Your expertise helps ensure that AI systems:
Deliver accurate, helpful, and empathetic customer support
Align with enterprise service standards and policies
Are safe, reliable, and trustworthy across languages
Language Requirements
Native or professional fluency in one or more supported languages is required
Supported languages span 30+ global languages
Language-specific nuance is assessed through screening and task-based evaluation, not separate job descriptions
