Job Description
You will join a leading global R&D environment where advanced AI-driven applications support researchers in their daily work—from data analysis and statistical modelling to predictive insights and dashboarding.
These applications, built mainly with Shiny (R) and Streamlit (Python), are part of a growing analytics ecosystem running on a dedicated internal platform. The mission combines maintenance of existing AI/statistical tools and development of new data-driven applications based on real user needs.
You will act as a bridge between business users (researchers) and technical teams, ensuring applications remain reliable, scalable, and relevant.
What you will do
- Investigate and fix issues in AI algorithms (bugs, performance, data pipeline failures)
- Maintain and improve existing Shiny (R) and Streamlit (Python) applications
- Ensure stability after platform or dependency updates
- Develop new interactive modules (dashboards, analytics tools, reporting apps)
- Analyse business needs and translate them into technical solutions
- Optimize and refactor Python and R codebases
- Manage data pipelines and connectors (APIs, databases, files)
- Conduct testing (UAT, unit tests, integration tests)
- Collaborate with data scientists, statisticians, and business users
- Document all developments and processes (French & English)

Nice to have:
- Experience with GCP (BigQuery, Vertex AI)
- Knowledge of Docker and APIs (FastAPI, REST)
- Exposure to ML frameworks (scikit-learn, TensorFlow, PyTorch)
