• Based in Villeneuve d’Ascq (59)
• At least 1 day per week remote working

Non-technical skills
• Curious, resilient, and autonomous
• Fluent French, written and spoken

Technical skills (by priority)
• Python 3.12+ (typing, MRO, Annotated, etc.), Java

‍Role & responsibilities
• Strong focus on backend development for Cloud Data Engine software, including customer-facing APIs and potential internal tools

• Full-time position, reporting directly to the Chief Technical Officer, within an existing development team
• Following an initial interview, a take-home technical exercise may be requested

Here are examples of interview test-tasks which represent the type of work done in CDE. Feel free to have a look.
