• Apply learnings from creative metrics (CTR, CVR, hold rate, ROAS) to sharpen copy while maintaining brand voice.

Requirements

• 5+ years writing for performance/paid social (DTC/e-comm strongly preferred).
• Portfolio of live ads (share results where possible: CTR/CVR/ROAS or strong proxies).
• Fluency in Meta, TikTok, Pinterest, YouTube, Snap nuances and best practices.
• Ability to produce many high-quality variants quickly.
• Bonus: outdoor/active/lifestyle experience, CRO/landing-page chops, UGC scripting.

Details

• Start: ASAP
• Duration: Through mid-December (~2 months)
• Commitment: 20–40 hours/week
• Compensation: Competitive freelance rate (please share expectations)
