Senior Copywriter & AI Systems Architect

GlossGenius is the AI-powered system behind the world's most meaningful appointments, helping 120,000+ service businesses earn more revenue and free up time for the work they love. Our agentic workforce gets more clients in the door, grows profit per appointment, and keeps clients coming back — doing the jobs owners never had time for and couldn't justify hiring to fill. Businesses on GlossGenius process billions in annual payment volume, and see 65% more revenue using GlossGenius Payments by growing ticket size, rebooking clients at checkout, and saving on processing fees.

GlossGenius serves 120,000+ service businesses and the way we talk to them is a meaningful part of how we earn their trust and grow the business. Copy touches every surface that matters: paid social, email, landing pages, and campaigns. The quality of that copy directly affects whether someone signs up, activates, and stays.

The other half is architecting the AI-powered systems that embed your editorial judgment into how the entire marketing function produces copy, so quality and consistency don't depend on you being in every room.

You will report to the Director of Brand Marketing. You must be commutable to our NYC headquarters and will operate in an in-person environment. We default to being in-office 3–4 days per week with required attendance on Tuesdays and Thursdays.

What You'll Do

• Write across the full marketing funnel inclusive of paid social, email, landing pages, video scripts, and campaigns, bringing real business-owner pain points to life and showing how GlossGenius solves them in ways competitors don't
• Architect AI-powered copywriting and copy-review systems from the ground up, designing workflows that encode brand standards and scale copy quality across the org without requiring your direct involvement in every piece
• Build and maintain a living style guide and brand voice framework that serves as the foundation for every system you create and every piece of copy the team produces
• Set the editorial standard for the org, running AI-powered copy reviews, giving feedback with conviction, and coaching partners to make better messaging decisions independently
• Develop integrated campaign messaging, creative territories, and taglines that cut through competitive noise and make GlossGenius the obvious choice for service business owners

What We're Looking For

• 5+ years of copywriting experience with a portfolio spanning brand, performance, and lifecycle work across a marketing funnel
• You have built AI writing tools and workflows that changed how a team operates, with genuine hands-on experience designing systems rather than just using tools to write faster
• Comfortable moving without full direction, making calls on voice, messaging, and creative strategy without waiting for someone to scope it first
• Proven track record of translating product features into business impact and customer transformation, with a deep understanding that differentiation increasingly lives in narrative
• Experience setting copy standards at an organizational level, through style guides, voice frameworks, or AI-powered writing systems
• Strong performance marketing instincts, with a clear sense of what makes copy convert in crowded paid environments
• A clear point of view on what great looks like, the ability to defend it, and a track record of rallying cross-functional partners around a creative perspective
