You know that the best idea in the world doesn't matter if it doesn't stop a thumb in the first half-second—and you're just as energized by cracking that hook as you are by the bigger brand idea it ladders up to. You write fast, you write a lot, and you write in variations: five headlines when one won't do, a dozen hooks to find the one that earns the click. You're fluent in the native language of paid social—Meta, TikTok, YouTube, etc—and you know the difference between an ad that performs and an ad that just looks good in a deck. You're data-curious: you want to know how your copy actually performed, and you use that signal to write the next thing better. You're production savvy, from testable quick-turn UGC-style content to bigger campaign moments. You're ready for a challenge—something that satisfies and expands your craft, your curiosity, and your microbiome. This role reports to the Creative Director (Copy), and is an opportunity to do amazing work alongside a wonderful assemblage of talented and kind human beings. **What You’ll Do:** - Own Growth Creative Copy: Develop performance-driven concepts, hooks, scripts, headlines, supers, primary text, and CTAs across TV, Meta, TikTok, YouTube; Think beyond copy alone to how messaging comes to life within the full ad. - Write for Volume and Velocity: Generate large sets of testable copy variations to feed an always-on testing cadence, working closely with media buyers and performance marketers to know what's working and why. - Iterate on Performance: Use performance data (hook rate, CTR, CVR, CPA) to inform your next round of copy. You treat every test as a brief for the next one. - Extend Across the Funnel: Bring growth-minded copy to landing pages, email/SMS, and other conversion touchpoints, in addition to top-of-funnel ad creative. - Steward Brand Voice: Keep performance copy unmistakably Seed—consistent, clear, and on-voice—even when it's built to convert. Review ad scripts and copy developed by agency and external partners, providing clear, actionable feedback to ensure the work is on-brand, strategically sound, and built for performance. - Work Collaboratively: Partner with art directors, designers, motion designers, growth marketers / strategists, and cross-functional partners to ship work quickly and iterate on it faster. **Who You Are:** - Experience: A writer with five-to-eight years of experience—agency or brand-side—with a portfolio that includes real, running paid social and performance work, not just spec ads or brand campaigns. - Skillset: You're an excellent writer of hooks and headlines who can move fast without settling for the flip phrase or lazy pun. - Data Fluency: You're comfortable reading performance metrics and using them to shape your creative decisions—testing is part of your process, not an afterthought. - Culture: You're curious. You're dialed into what's happening in culture and on the platforms where your work lives. - Passionate: You give a shit. You care about The Work, whether it's a $2/day test or a flagship campaign. - Production: Experience working on productions big and small—from quick-turn UGC-style content shoots to campaign-level work. - Comfortable moving from macro to micro—no project, and no single ad variation, is too small to tackle with positivity.
