Every ad is a hypothesis. Every test is a learning opportunity. And every win is shared. This is a chance to build - creative systems, testing frameworks, and eventually, your own creative team. If you love finding the sweet spot where art meets algorithm, you’ll feel right at home.

Partner with performance media buyers to develop and execute data-driven creative strategies.
Build briefs for designers, editors, and UGC creators that turn insights into actionable direction.
Run structured creative testing frameworks (A/B, multivariate) to identify winning concepts.
Analyze creative performance metrics (CTR, CVR, CPA, ROAS) and iterate quickly based on results.
Stay ahead of platform trends, hooks, and consumer psychology across TikTok, Meta, and YouTube.
Develop creative systems - how ideas are generated, tested, and scaled.
(Growth path) Build and lead a creative team as we expand.

Who We're Looking For

3–5+ years in performance marketing, creative strategy, or paid social roles.
Proven record of producing high-performing ad creatives across Meta, TikTok, or Google.
Strong analytical mindset - you know your way around CTR, CVR, CPA, and ROAS data.
Skilled in briefing and collaborating with designers, editors, and UGC creators.
Deep understanding of what makes ads convert - hooks, emotions, and storytelling structure.
Passion for consumer psychology and staying ahead of creative trends.
(Bonus) Experience building creative operations or managing a creative team.

€3,500 - 5,000/month + meaningful equity own a part of what you build. (open to negotiation based on experience and fit)
Real ownership - your creative decisions will directly shape performance and growth.
Fast experimentation culture - we test daily, learn fast, and move on data.
Opportunity to build creative systems and a team around you.
Hybrid setup in Vilnius with flexibility for the right candidate.
