Senior Growth Copywriter

Who you are

• You're a growth-obsessed copywriter who lives and dies by the scroll
• 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
• 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

What the job involves

• 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
• 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
