AI Agent CX Lead Intern (Internship)

The Role

We are looking for a final-year student or young professional to join our Operations team for a 6-month internship and own the customer experience validation of our AI voice agents before they go live.

Your mission will be to ensure every agent feels natural, clear, culturally adapted, and aligned with the customer’s brand expectations — across tone, vocabulary, conversation flows, accents, and overall experience quality.

This is not a traditional QA or engineering role. We are looking for someone with a strong customer experience instinct, able to judge whether an interaction actually feels good from an end-user perspective.

You will work closely with our implementation, delivery, and commercial teams to refine agents before launch and help define the quality standards behind enterprise-grade conversational experiences.

• Own the CX validation of AI voice agents before production launch, ensuring conversations feel natural, fluid, and aligned with each customer’s brand expectations
• Test and review conversational flows end-to-end across multiple languages, validating tone, clarity, empathy, vocabulary, accents, transitions, and overall customer experience quality
• Design and maintain validation frameworks covering edge cases, hallucination gaps, consistency checks, and stress tests
• Hire, coordinate and manage multilingual testers and external reviewers when needed, ensuring tests are executed consistently across languages, regions, and use cases
• Build automated validation workflows to scale regression testing as we deploy more agents

Requirements

What we’re looking for:

• Final-year Master’s student or young professional with a strong Customer Experience (CX) mindset
• Background in Customer Experience , Hospitality, Marketing, Communication, Customer Service, Languages, or similar fields
• Multilingual profile : fluent in English and French mandatory, Portuguese, German, or Spanish are strong pluses
• Excellent communication and strong sensitivity to tone, language nuances, and conversational quality
• Strong leadership skills to coordinate and manage a distributed team of testers
• Highly organized, detail-oriented, and comfortable managing multiple projects in parallel
• Comfortable with ambiguity and able to figure out what needs to be tested, structured, and improved

Benefits

What we offer

• A 6-month paid internship with direct impact on daily operations
• Hybrid work setup with a minimum of 4 days/week in our Paris office
• High ownership and autonomy
• Diverse, international team across Europe
• Exposure to cutting-edge AI, voice, and enterprise deployments
• Fast-paced environment with strong learning curve
