Performance & Growth

• Build and scale creative-driven acquisition funnels
• Produce performance creatives for paid channels (Meta, TikTok, Google, YouTube)
• Work closely with media buyers to test, analyze, and scale winning creatives
• Continuously run creative experiments (A/B testing, iterations, new formats)

Creative Systems & Scaling

• Work with UGC creators, designers, and editors to produce high-volume creatives
• Identify trends, insights, and opportunities in the U.S. digital landscape

• Hands-on experience with short-form video and UGC formats
• Ability to combine creative thinking with data-driven decisions
• Background in IT product / mobile apps / DTC / beauty / wellness is a strong plus
• English: Upper-Intermediate+

❌ Not a Fit If

• You focus only on brand/content without performance metrics
• You have no experience with paid acquisition creatives
• You are looking for freelance / consulting / part-time work

💎 What We Offer

• Competitive above-market salary
• Official employment from day one
• 30 calendar days of paid vacation + sick leave
• Remote / hybrid format with Kyiv office option
• Strong onboarding and support
• Opportunity to build and scale a global creative engine from scratch

If you think in hooks, test ideas daily, and scale what works — we should talk.
