Gen AI Engineer (M/F) - Internship - Paris

Your missions

As a Generative AI Intern, you will join Wiremind’s emerging GenAI team and work directly under the supervision of our Lead GenAI Engineer. You’ll contribute to developing LLM‑powered features that help airlines and railways make better pricing and operational decisions.

The GenAI projects you’ll work on

Our team is building LLM‑based systems to analyze services (flights, trains), recommend pricing actions, and help revenue managers define automated strategies using natural language.

What the job looks like in practice

• Design and run experiments to test different approaches for the projects above
• Prompt engineering through systematic testing and refinement
• Develop evaluation frameworks including LLM‑as‑judge approaches and metrics aligned with expert preferences
• Benchmark LLM models (GPT-4, Claude, etc.) to find optimal cost/performance tradeoffs for production constraints
• Break down complex problems into simpler, specialized sub‑tasks that LLMs can handle more reliably
• Analyze failure modes and edge cases in LLM outputs
• Document and share your findings with the broader engineering and product teams
