• Hands-on experience working with UGC or influencer content for physical products is a strong plus
• Basic understanding of key marketing and performance metrics
• Creativity combined with the ability to translate ideas into clear, actionable briefs
• Experience writing scripts or briefs for UGC creators or influencers
• Familiarity with Meta Ads Manager and/or TikTok Ads
