In 2026, a data scientist in France earns €45–58k junior, €55–73k mid, €73–92k senior and €90–120k+ at lead/principal level. Profiles leaning toward machine learning, LLM/GenAI and applied/research science sit at the top; the more generalist "analytics" data scientist sits a notch below. At equal seniority the gap comes from specialty, sector and international remote. This guide drills into the data scientist role within the data salary overview.

By specialty

• Analytics data scientist (classic modelling, experimentation, A/B testing): the core, most common range.
• ML scientist (models in production, deep learning): top of the range, close to the ML engineer — the line is thin and the pay gap small.
• Research / applied scientist (R&D, publications, PhD profiles): the highest ranges, especially in AI labs and GenAI scale-ups.
• NLP / LLM / GenAI: the most visible 2026 premium — a well-placed LLM skill is worth several years of seniority.

Region, remote and freelance

Paris holds the top ranges (scale-ups, AI labs), but remote narrows the gap and opens international grids (15–30% above local). Compare Paris or remote. Freelance day rates: €450–600 (mid), €600–850 (senior), higher for rare ML/LLM profiles.
