Python AI Developer (M/F)

Paris/Lille | Insurance sector

Why this opportunity?

Because you will participate in the construction of our artificial intelligence strategy, which we are currently defining.
You will join a motivated and talented team, whose mission is to integrate AI into the heart of our business processes.

The objective is to meet the needs of our teams as well as those of our clients, and to automate certain low-value tasks added.

Key elements

• Design RAG and agentic solutions applied to concrete business use cases.

• Develop and orchestrate agents while ensuring source traceability and control of hallucinations.

• Contribute directly to the KELIA product configuration workflow, with human validation integrated into the steps keys.

• Participate in the production of the assistants, from their API to their integration into the internal web interface.

What you need to know:

We are looking for a Python AI Developer to join our R&D team in Paris or Lille

You will be involved in the entire life cycle of solutions, from design until production, by mobilizing different approaches: language models (LLM), supervised learning, clustering and other machine learning techniques.

An important part of the mission also concerns product configuration: the objective is to extract relevant information from the general conditions, to propose a configuration, to provide validation by an expert at each stage and to produce a file directly importable into KELIA.

Main missions :

You develop AI functionalities in Python.

• Document ingestion: extract text and tables from PDFs, Confluence pages, SharePoint documents and GitLab repositories, then slice, index and update this content with asynchronous jobs.

• Search: hybrid search (semantics and keywords), filters by collection and by path, reranking, and visual search on document pages.

• Agents and LLM: develop agents with LangGraph (routing, search, filtering, reflection, response), write and version prompts, cite sources, and respond “I can't find” when information is missing.

• Product configuration workflow: contribute to the agent which extracts information from conditions general, proposes the configuration, has each step validated by an expert and produces an importable file in KELIA.

• Quality: maintain test sets, measure the rate of correct answers, follow the invented answers and check that the results are stable from one run to another.

• Cost and latency: monitor the consumption of tokens, the first response time and the cache, and choose the right model for each task.

• API: Expose API wizards, with streaming responses, and integrate them into the internal web interface.

• Document your code, write tests and participate in code reviews.

This position is for you if:

• You have a Bachelor's degree in computer science or assurance

• You are proficient in Python 3.11+ and are comfortable with API development via FastAPI, Pydantic and SSE streaming.

• You have experience or a real interest in generative AI solutions, LLMs and agentic architectures with LangChain, LangGraph and LiteLLM.

• You know the principles of RAG, hybrid search, embeddings and reranking, ideally with Qdrant.

• You know how to work with various document sources and their ingestion, including PDF, Confluence, SharePoint or GitLab, with tools such as Docling.

• You are comfortable with storage and persistence environments based on PostgreSQL and object storage S3.

• You attach importance to the observability and quality of AI solutions, in particular the monitoring of prompts, traces, logs, costs and performance, with tools like MLflow.

• You are aware of the issues of security, authentication and role management, in particular with Keycloak.

• You operate with ease in a modern industrialization environment using Git, GitLab CI, Docker, Kubernetes, Helm and pytest, as well as collaborative tools like Jira and
