Stage Développeur·euse IA - LLM, RAG & Whisper

Full-Stack Developer Intern (Python / Angular / GCP / LLM) Datelia · Paris · End-of-studies internship · 6 months, We're looking for an intern who wants to get their hands on everything: backend, frontend, infra, AI. You'll work directly with the tech team on the production platform - not on an isolated side project.

Depending on your interests and where things stand, you'll contribute to:

• Product features on both backend (Python) and frontend (Angular)
• Integrating new models through our LiteLLM routing layer (OpenAI, Anthropic, Mistral, Vertex AI)
• RAG and agentic workflows with LlamaIndex
• GCP infrastructure (Cloud Run, Cloud SQL, Pub/Sub, BigQuery, Vertex AI)
• Observability, testing, and CI/CD
• Prototyping new AI features

You won't do all of this in six months - but you'll touch several layers of the stack and understand how a real SaaS platform holds together, with real customers depending on it.

• Final year of engineering school or equivalent master's, with a specialization in IT, data, or AI
• Comfortable in Python; ideally some exposure to Angular
• Curious about LLMs and the engineering around them: RAG, agents, evaluation, prompt engineering
• Prior exposure to GCP or another cloud is a plus

On the mindset side - what actually matters to us:

• Genuine customer focus. Behind every line of code, there are users who need to get value from it. We don't ship for the sake of shipping.
• A taste for doing things well. Clean, tested, documented code. Better to finish one thing properly than to rush three features out the door.
• Good listening. You take the time to understand a requirement, a piece of customer feedback, or a colleague's comment before jumping to a solution.
• Eagerness to learn. This space moves fast - we're all learning constantly. We'll give you time and resources for that.
• Curiosity about the why. You want to understand why a technical decision was made, not just execute a ticket.
• Autonomy with good judgment. You can work independently and know when to ask for help.

A personal project, a GitHub repo, an open-source contribution, or a side project will speak louder than a formatted cover letter. If you've built something with an LLM - even something small - show us.
