About GuestButler

GuestButler builds the invisible AI host for hospitality.

Our AI agent communicates with hotel and vacation park guests via WhatsApp, handling questions, upsells and operational requests in real time. Not as a chatbot, but as a human-like assistant that feels natural, helpful and on-brand.

The Role

This is not a typical internship.

You’ll operate close to a junior engineer level and work directly on improving how our AI behaves in production.

Your focus is not “training models”, but improving agent quality:

how responses are structured
how context is used across turns and systems
how tone of voice feels per brand and situation
when the agent should act, escalate or stay silent

You’ll combine engineering, analysis and experimentation to make our AI more human, reliable and scalable.

What You’ll Do

Research:

Investigate tools and methods to evaluate AI conversation quality
Break down real guest conversations and identify what works and what doesn’t

Develop:

Build and test improvements in prompts, agent logic and conversation flows
Implement guardrails and feedback loops
Contribute code that turns feedback into product improvements

Collaborate:

Work closely with product and engineering to ship improvements to production
Align your work with goals like better integrations, smoother guest journeys and smarter upsells

Who You Are

MSc student or recent graduate in Computer Science, AI, Data Science or similar (strong BSc can also fit)
Comfortable writing code (Python, JavaScript or similar)
Curious about how LLM-based systems behave in real-world environments
You like figuring things out instead of waiting for instructions
Able to think in systems, not just outputs
Clear communicator who can document and explain your work

Nice to Have

Experience or interest in AI agents, chatbots, LLMs or prompt engineering
Interest in evaluating AI quality beyond “does it work?”
Interest in hospitality tech or customer-facing systems
Experience working with logs, transcripts or real user data

What You’ll Get

Hands-on experience with a production AI system used by real guests
Direct impact on a core product
Close collaboration with founders and senior engineers
A steep learning curve in how AI products actually get built and improved
Internship compensation and potential to continue after the internship

Why This Internship Is Different

This is not a research-only role.

Your work will go live. Guests will feel the difference.

We’re looking for someone who wants to operate at a higher level than a typical intern and grow into a full-time role.

Hiring Process

2 interviews
1 small technical test
Fast process, clear feedback
