[Hiring] Copywriter - Conversion & Growth @Cro Metrics

Role Description

As Cro Metrics continues to scale its integrated growth marketing services, the creative team is expanding to meet rising demand across paid media, CRO experimentation, website design, and lifecycle marketing. This role is part of a strategic hiring plan to bring on reliable, high-quality creative talent that strengthens our ability to deliver hypothesis-driven, conversion-focused copy across every client touchpoint.

This is a conversion copywriting role. You'll write the words that go inside paid ads, landing pages, experiments, and email campaigns, primarily for B2B and B2C clients. Every line you write has a hypothesis behind it and a test in front of it. You'll also build and manage brand-specific AI writing agents that scale our copy output while preserving voice integrity. You'll work closely with strategists, designers, and analysts to produce copy that moves metrics, not just reads well.

This is a long-term fractional contractor role. Most contractors stay on contract, as the relationship is designed to be sustainable at part-time hours, which flex with client contract cycles. Conversion to full-time employment happens selectively when there's a clear business need and mutual interest. Either way, we're looking for someone we can build with long-term.

What You'll Do

• Write paid media ad copy across platforms (Meta, Google, LinkedIn), including 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, including headline variants, CTA copy, value proposition rewrites, and messaging hierarchy tests.
• 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, ensuring 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, creating custom prompts, voice calibration files, and guardrails to ensure AI output stays on-brand.

Qualifications

• 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.
• Strong strategic instinct; understanding why copy converts, not just what sounds good.
• Experience writing for digital channels: web (landing pages, PDPs, funnels), paid media (social and search ads), and email/SMS.
• Comfort with volume and speed, producing multiple variants quickly without sacrificing quality or strategic thinking.
• Clear communication skills; asking good questions about briefs and explaining copy rationale to non-writers.
• Self-directed and reliable; managing time well and meeting deadlines consistently.
• Active, demonstrated use of AI tools in your daily workflow.

Requirements

• Experience at an agency or in a multi-client environment managing competing priorities and fast turnarounds.
• Experience writing copy for CRO, experimentation, or growth 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 or similar tools configured with brand voice and output guardrails.

What Success Looks Like

• Consistently delivering on-brand, hypothesis-driven copy on time and with minimal revision cycles.
• Strategists and designers trusting your copy output and viewing you as a reliable creative partner.
• Managing a steady cadence of deliverables across multiple clients without quality or strategic rigor dipping.
• Every variant you write having a clear rationale, with the ability to explain why each one should win.
• Proactively flagging brief gaps and communicating about capacity honestly.
• Building reusable copy frameworks and swipe files that enhance team efficiency.
• Maintaining AI writing agents that produce on-brand first drafts and keeping them calibrated as client voices evolve.
• Moving fluidly between B2B and B2C clients without a drop in quality.
