• You’ll start lean with the first step — CRO function (landing/checkout/onboarding/paywall optimization). Once built, we’ll define the next team scope of your growth engine within 3–6 months.

   

Why You’ll Love Working at Promova

• 🌍 Impact: Help shape Promova’s culture for a global, growing team.
• 💡 Freedom: Hybrid setup, flexible schedule, and real ownership.
• 🚀 Growth: Continuous learning, conferences, mentorship, and English classes.
• 💙 Wellbeing: 20 paid vacation days, mental health support, and insurance.

• 🎉 Community: You’ll create events and traditions that people will remember.
