Is This Role For You?

For You If
  • You're a student or recent grad who wants to understand how SEO directly drives SaaS acquisition and revenue
  • You're comfortable with technical SEO tools (GSC, Analytics, SEMrush/Ahrefs) and eager to level up your proficiency
  • You're detail-oriented and can execute optimization work independently while collaborating with a wider team
  • You speak French fluently and ideally have basic knowledge of Spanish or English (multi-market work required)
Won't Work If
  • You're looking for a permanent role—this is a 6-month internship with no guarantee of extension
  • You need full remote flexibility—this is on-site only in Paris
  • You have no interest in technical SEO or analytics—the role is heavily hands-on with tools, not just content
