About The Position

About Anthropic Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems. About the role We're looking for a Copywriter with a blend of agency advertising background and in-house experience. You can concept and ship campaigns, have experience across categories and product types, and know how to write for audiences that bring tension to the room. Ideally you've worked on a brand where trust itself was the line to walk. At minimum, you've written for specific audiences where the easy, consumer-shiny line was the wrong one, and found something more honest that still moved people. This role sits within the Creative Studio and leads copy for brand campaigns for Claude. You'll partner with art directors and designers to concept at the highest level, and carry the work all the way down to the last headline in execution. Whether the starting point is a fully fleshed brief or just an idea, you know how to build the work out from there. You'll also work closely with our Head of Copy to keep evolving Claude's voice and tone through the campaign lens. That means your day-to-day writing isn't just output, it's input into how the brand voice grows. The guidelines are still in growth mode, and Claude's voice flexes across other audiences and parts of the business, so you'll have a foot in both worlds: shipping campaign work and shaping the broader writing system.

Requirements

12+ years of experience with a portfolio rooted in campaign work, showing concept development and execution across multiple channels and formats.
Have worked both in-house and at agencies, across a variety of companies and product types, and can speak to what each side taught you.
Have a strong advertising portfolio: brand campaigns executed with high craft across film, OOH, social, and digital.
Think conceptually and build while you go.
You've been in startup mode, you can start from the smallest of briefs, and you don't need a finished strategy to make progress.
Push beyond the brief when you're given one, and bring back something better than what was asked for.
Have written for nuanced subjects and audiences where trust was at stake.
Have worked with a voice and tone that was still taking shape, and helped it grow, contributing to guidelines through shipped work rather than waiting for them to be finished.
Understand what stays fixed and what moves when a brand voice flexes across audiences, and can articulate it.
Operate at a senior level: independent enough to drive work yourself, collaborative enough to make cross-functional partners better, and consistent about getting work shipped.

Nice To Haves

A brand that had to thread a trust-and-safety line is a plus

Responsibilities

Lead copy for Claude brand campaigns end to end: campaign platforms, manifestos, headlines, film and audio scripts, OOH.
Work from any starting point, from a fully fleshed brief to just an idea, and push the work forward.
Write with nuance for audiences that bring real tension to the subject: calibrate claims, meet skepticism head-on, and earn trust without flattening the idea or the voice.
Partner cross-functionally with brand marketing, media, product marketing, and comms to get campaign work shipped, with the independence to drive it and the collaboration to make it better.
Understand how the Claude voice flexes across the rest of the business, including enterprise, developer, and product, and keep campaign work coherent with the whole.
Build on Claude's voice and tone foundations as you go, and feed what campaign work teaches you back into the guidelines.
Hold the bar through production: scripts in the edit, lines in the layout, copy through legal and review without losing what made it great.
