Voodoo’s gaming hub in Paris — Aura team members are welcome there!

We’re a team built by founders who’ve scaled Voodoo (€625M revenue). We’ve secured seed capital from top-tier investors behind BeReal, Deel, Voodoo, and AppLovin—and are now taking on an AI-driven health app to own the next big category in health & fitness.

You’ll work side-by-side with the Creative Lead—a performance-minded leader with hands-on experience. You’ll work on turning ideas into high-performing video ads. You’ll take ownership of competitive research, creative production, and rapid pivoting.

 About the Product

Aura is an AI-powered wellness coach that helps people understand and improve their health based on real data — not guesswork.

The product combines lab testing, biomarker analysis, and AI-driven insights to identify what’s actually affecting a person’s energy, focus, mood, and overall well-being. Instead of generic advice, Aura provides personalized recommendations (nutrition, supplements, lifestyle) tailored to each user’s biology.

• B2+/C1-level English (work in English daily).
• Experience launching new products/flows/brunches from scratch and scaling them to $100k+/month would be a huge plus.

 Soft Skills We Value

• Speed & Persistence. You move fast, run constant creative tests, and keep momentum even when early results miss the mark—knowing that breakthroughs often come right after setbacks.
• Autonomy. You can run creative cycles independently and don’t wait for direction.
• Responsibility. You care deeply about results and treat metrics like ROAS and CPA as key indicators of your impact—not just numbers on a dashboard.
• Curiosity. You’re constantly analyzing, researching, and pivoting for new angles.
• Thrives in early-stage companies and sees the 0→1 phase as the moment to shape the foundation.

• Launch and test multiple new creative hypotheses
• Brief designers and iterate on creatives daily
• Analyze performance (ROAS, CPA, CTR) and kill/scale fast
• Research competitors via Ad libraries and spy tools

• You optimized existing funnels but never built from scratch
• You prefer stable, predictable environments over fast-paced startups
