Reenbow is an innovative EdTech company that is developing a learning platform powered by artificial intelligence, capable of generating tailor-made educational content and maintaining a high level of engagement among learners. We are exploring the power of LLMs (Large Language Models) to create intelligent conversational agents for training purposes. And we are looking for a Data Scientist AI to strengthen this dimension. Your missions: Design, test and optimize advanced prompts for different educational scenarios (game, quiz, tutored conversation...). Train and fine-tune LLM models (GPT, LLaMA, Mistral...) to create conversational agents adapted to our use cases. Prototype and deploy intelligent AI agents, capable of guiding, motivating and correcting learners in real time. Create workflows with LangChain, OpenAI API, Hugging Face, and other modern AI frameworks. Work with the product team to imagine the new AI features of our platform. Carry out active and strategic monitoring: new LLMs, open-source frameworks, benchmarks, cutting-edge papers... and test, always test.
