Job Description

Responsibilities

  • 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.

Requirements

  • 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.

Benefits

  • Health & Wellness : Choose from multiple medical, dental, and vision plans, with generous employer contributions and coverage options to meet your needs. Enjoy access to top-tier virtual care and a complimentary Aaptiv membership for fitness and mental wellness. We also provide an HSA with employer contributions, along with Fullscript discounts for supplements.
  • Mental Health Support : All employees and eligible dependents receive 12 free therapy sessions per year, plus coaching, meditation, and 24/7 access to Spring Health’s digital tools and care navigation.
  • Long Term Wealth Planning : Invest in your future with our 401(k) plan through Betterment, featuring a 100% match on the first 3% and 50% on the next 2% of contributions—fully vested from day one.
  • Supporting Families : Our Parental Leave Policy includes 18 weeks of fully paid leave, with the flexibility to phase your return. We also offer four weeks of paid transition time at 80% capacity or four days per week.
  • Time to Recharge : Seed offers 15 vacation days, 7 sick/safe days, 2 personal days, 10 Recharge Days (Summer + Winter), and 15 paid company holidays each year.
  • Work Flexibly : Thrive in a remote-first culture that prioritizes autonomy and clarity. You’ll also receive a $750 one-time remote work setup stipend and ongoing access to a $450 quarterly wellness and workplace stipends via JOON.
  • And More : Access pet insurance, life and disability coverage, learning & development, and a vibrant culture rooted in science and impact.
