Job description

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.

Track A: Customer Service & Support AI Rater

Raters execute structured evaluation tasks using clearly defined rubrics and instructions.

Responsibilities

  • Evaluate AI outputs related to customer service and support interactions

  • Perform structured scoring, comparison, classification, and judgment tasks

  • Assess accuracy, clarity, tone, helpfulness, and alignment with support best practices

  • Identify hallucinations, misleading responses, policy violations, or unsafe guidance

  • 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

Track B: Customer Service & Support AI Evaluator (Senior Track)

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

Evaluation Focus & Requirements

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

What We Look For

  • Deep domain expertise in customer service, support operations, or CX

  • Strong judgment and ability to apply criteria consistently

  • Comfort working with structured evaluation workflows

  • Ability to explain reasoning clearly, especially in sensitive customer scenarios

  • Reliability, professionalism, and respect for quality standards

Engagement Model

  • Contract-based, flexible participation

  • Project-based work with clear expectations and timelines

  • Opportunities for recurring work based on performance and demand

  • Compensation communicated upfront per project or task type

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

  • English fluency is required for guidelines, feedback, and collaboration
