Copywriter Jobs in California

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

As a Copywriter, Developer at Anthropic, you will shape how our brand speaks to developers, an audience that is notoriously allergic to being marketed to and quick to spot anything that doesn't ring true. Developers who stay sharp, curious, and direct AI tools with their own judgment are the ones who will thrive, and your job is to help that idea land authentically rather than arrive as a slogan. You'll co-create a voice that developers recognize as empathetic, direct, and genuinely useful, and you'll bring that voice to every place our brand meets a developer.

In this role, you'll own the brand-led developer writing that sits between Dev Rel's technical content and pure marketing: launch narratives, campaign work, social, paid, event materials, and developer work that shows up in enterprise contexts. You'll partner closely with Dev Rel as an embedded extension of their team, co-own the developer voice and tone guide with Comms, work with Claude Code and developer marketing leadership on strategic initiatives, and sit within a developer creative pod alongside a brand designer and program manager, with our Head of Copy and Content as your craft lead.

Responsibilities

• Own the developer-facing expression of brand campaigns, starting with Keep Thinking, translating brand-level ideas into writing that works across launches, social, and paid
• Build the developer voice and tone guide in partnership with Comms and Dev Rel, then turn it into the templates and examples the creative team uses for developer work
• Own the brand-led developer assets that sit between technical content and marketing, from event and campaign materials to developer writing in enterprise contexts
• Partner daily with Dev Rel as an embedded extension of their team, complementing the technical content they own rather than duplicating it
• Develop launch narratives and short-form copy that adapt expert, technical material into sharp, accurate writing developers trust
• Lead copy for the developer creative pod, working side by side with brand design and program management to ship integrated work
• Partner with Claude Code leadership and developer marketing leadership on strategic initiatives that shape how we show up for developers
• Present work and a clear rationale for voice and craft decisions to stakeholders across Brand, Dev Rel, Comms, and marketing
• Manage feedback from technical reviewers and Comms so that what ships is both accurate and within what we can say externally
• Track how developer-facing work lands and use what you learn to sharpen the voice, the templates, and the work itself

You may be a good fit if you

• Have 8+ years experience writing for developers or technical audiences, and a portfolio that shows both technical and brand work
• Have shipped work that developers actually shared, whether in-house at a developer tools or infrastructure company or at an agency serving those clients
• Have a strong, specific point of view on how brands should talk to developers, and can articulate it with examples
• Can read a changelog or a docs page and explain why a developer would or wouldn't trust it
• Are skilled at adapting expert material into sharp short-form copy and launch narratives without losing accuracy
• Work fluidly across the full range from technical content to pure brand writing
• Already use Claude or other AI models in your own writing practice and can talk concretely about how
• Enjoy embedding with technical teams and treating engineers and Dev Rel as creative partners, not just reviewers
• Are comfortable co-owning standards with other teams and knowing where your lane ends and theirs begins
• Are excited about Anthropic's mission to develop AI that is safe and beneficial

Strong candidates may also have

• Experience working directly alongside a Dev Rel or engineering team rather than through a brief
• Built or contributed to a voice and tone guide, style system, or writing templates that other people successfully used
• Written for developer launches at a fast-moving product company, where accuracy and speed both mattered
• Familiarity with the AI developer ecosystem, including coding tools, APIs, and how developers evaluate them
• Experience writing developer-credible work that also performs in enterprise or executive contexts
• A personal writing practice, newsletter, or public work that demonstrates voice and judgment
• Worked within brand campaign systems and translated them for a skeptical or specialized audience

Location-based hybrid policy: Currently, we expect all staff to be in one of our offices at least 25% of the time. However, some roles may require more time in our offices.

Visa sponsorship: We do sponsor visas! However, we aren't able to successfully sponsor visas for every role and every candidate. But if we make you an offer, we will make every reasonable effort to get you a visa, and we retain an immigration lawyer to help with this.

We encourage you to apply even if you do not believe you meet every single qualification. Not all strong candidates will meet every single qualification as listed. Research shows that people who identify as being from underrepresented groups are more prone to experiencing imposter syndrome and doubting the strength of their candidacy, so we urge you not to exclude yourself prematurely and to submit an application if you're interested in this work. We think AI systems like the ones we're building have enormous social and ethical implications. We think this makes representation even more important, and we strive to include a range of diverse perspectives on our team.

Your safety matters to us. To protect yourself from potential scams, remember that Anthropic recruiters only contact you from @anthropic.com email addresses.

How we're different

We believe that the highest-impact AI research will be big science. At Anthropic we work as a single cohesive team on just a few large-scale research efforts. And we value impact — advancing our long-term goals of steerable, trustworthy AI — rather than work on smaller and more specific puzzles. We view AI research as an empirical science, which has as much in common with physics and biology as with traditional efforts in computer science. We're an extremely collaborative group, and we host frequent research discussions to ensure that we are pursuing the highest-impact work at any given time. As such, we greatly value communication skills.

The easiest way to understand our research directions is to read our recent research. This research continues many of the directions our team worked on prior to Anthropic, including: GPT-3, Circuit-Based Interpretability, Multimodal Neurons, Scaling Laws, AI & Compute, Concrete Problems in AI Safety, and Learning from Human Preferences.
