- Turn research insights into working proofs of concept, then partner with technical teams to integrate the most promising solutions into our products and services.
What you'll bring
- A genuine passion for generative AI and an appetite for hands-on R&D challenges.
- Strong autonomy, organisation, and communication skills so you can share findings clearly across the company.
- Alignment with our values of rigour, responsibility, humility, and kindness.
- French language proficiency.
- Bonus: prior experience with state-of-the-art computer-vision or NLP technologies such as Transformers, large language models, or parameter-efficient fine-tuning methods.
