Data Scientist GenAI

As part of our broader Data team (60+ people), you’ll prototype, iterate, and ship algorithms to production that impact marketplace catalog challenges—from NLP to large-scale Generative AI with custom LLMs. The opportunity can be located in Paris or Bordeaux and requires 4 days onsite per week, 1 day remote.

• Build and deploy ML algorithms to production that power 500+ e-commerce and marketplace sites in 40 countries, directly impacting revenue growth, operational efficiency, and transaction safety.
• Tackle real‑world catalog challenges including automatic content rewriting, product attribute extraction from images and text, variant detection, product categorization, seller onboarding automation, and trending product prediction.
• Work with cutting‑edge AI techniques including multimodal models and LLM fine‑tuning—Mirakl is one of the few French players with fine‑tuned LLMs in large‑scale production.
• Own your projects end‑to‑end : from data analysis and prototyping to production deployment with Data Engineers and dev teams, plus building dashboards to monitor algorithm performance.
• Collaborate across teams to refine use cases, user experience, and integration paths while presenting results at weekly data science meetings.

What You’ll Bring to the Role

Experience :

• 4+ years as a Data Scientist with strong hands‑on NLP and applied ML in industry.
• Proven track record of deploying Machine Learning algorithms to production.
• Experience with Spark development for large‑scale data processing.

Skills :

• Expertise in NLP and Computer Vision algorithms and state‑of‑the‑art architectures (e.g., Transformers).
• Proficiency in Python and TensorFlow and/or PyTorch.
• Knowledge of the latest LLMs and fine‑tuning techniques.
• Data‑driven, pragmatic, and business‑oriented approach.
• Strong ownership and autonomy with excellent team collaboration.
