What you'll do

  • Write paid media ad copy across platforms (Meta, Google, LinkedIn). This includes headlines, descriptions, and creative copy that drives clicks and conversions.
  • Produce landing page copy from briefs and wireframes, collaborating with designers to ensure messaging and layout work together.
  • Write conversion-focused copy for A/B tests. This could include headline variants, CTA copy, value proposition rewrites, and messaging hierarchy tests where each variant is mapped to a clear hypothesis.
  • Write email and SMS copy for lifecycle campaigns (welcome flows, abandoned cart, win-back, promotional sends) within client brand voice guidelines.
  • Rewrite underperforming copy based on test results and analytics, diagnosing what's not working and proposing data-informed alternatives.
  • Adapt quickly to new client brand voices, absorbing voice guides and existing copy to produce on-brand work from the first deliverable.
  • Collaborate closely with strategists on hypothesis development. Your copy is the execution layer of their experimentation roadmap.
  • Manage your workload across multiple concurrent clients and projects, communicating proactively about capacity, timelines, and blockers.
  • Use AI tools to accelerate drafting, variant generation, and research while maintaining the craft, originality, and strategic rigor that make great copy.
  • Build, train, and manage brand-specific AI writing agents.
  • Create custom prompts, voice calibration files, and guardrails so AI output stays on-brand for each client.
  • Maintain and iterate on these agents as client voices evolve.

What they require

  • 2–4+ years of experience in conversion copywriting, direct-response writing, CRO copy, or performance marketing copy.
  • Experience writing paid media copy (Meta, Google, LinkedIn) with awareness of character limits, platform specs, and creative best practices.
  • A portfolio demonstrating copy that was written to be tested, such as paid ads, landing pages, headline variants, or email campaigns with clear strategic framing.
  • Ability to write across multiple brand voices quickly and accurately.
  • You can absorb a voice guide and produce on-brand copy on the first pass.
  • Strong strategic instinct.
  • You understand why copy converts, not just what sounds good.
  • You think in hypotheses, value propositions, and objection handling.
  • Experience writing for digital channels: web (landing pages, PDPs, funnels), paid media (social and search ads), and email/SMS.
  • Comfort with volume and speed.
  • You can produce multiple variants quickly without sacrificing quality or strategic thinking.
  • Clear communication skills.
  • You ask good questions about briefs, flag ambiguity early, and explain your copy rationale to non-writers.
  • Self-directed and reliable.
  • You manage your time well, meet deadlines consistently, and don't need to be micromanaged.
  • AI is a hard requirement, not a preference.
  • This role requires active, demonstrated use of AI tools in your daily workflow.
  • You'll be expected to build and manage brand-specific AI writing agents that the team can use at scale.
  • You'll be asked to show concrete AI-integrated workflows and agent-building experience during the interview process.
  • Candidates who cannot demonstrate practical AI tool use and agent creation will not advance.
  • Experience at an agency or in a multi-client environment where you managed competing priorities and fast turnarounds.
  • Experience writing copy for CRO, experimentation, or growth marketing, not only just brand or content marketing.
  • Experience writing paid media and email copy with awareness of character limits, platform specs, and creative best practices.
  • Demonstrated experience building AI writing agents, such as custom GPTs, Claude projects, or similar tools configured with brand voice, tone rules, and output guardrails for specific clients.

Benefits

  • The first 5–10 business days of the engagement are a paid evaluation period.
  • You'll do real client work at your full contract rate.
  • In all three cases, we'll tell you why and pay for all hours worked.
  • Potential for full-time conversion based on business need.
