Stage Développeur·euse IA – LLM, RAG & Whisper

**Full-Stack Developer Intern (Python / Angular / GCP / LLM)** Datelia · Paris · End-of-studies internship · 6 months **The role** 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. **Profile** On the technical side: * 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. **Conditions** * Conventional end-of-studies internship, 6 months, flexible start date * Paris, partial remote work possible * Compensation: €1,500/month gross **To apply** Send your CV and a few lines about what interests you to job@datelia.ai. 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.
