Brand Copywriter (Part-Time, Freelance)

Mozilla Foundation works on some of the hardest questions in tech: how AI gets built and governed, who the internet serves, and what a healthier digital world actually looks like. The thinking behind that work is rigorous, drawing on research, policy analysis, and years of expertise. We're looking for a copywriter who can unlock that thinking—someone who can take a dense idea, understand it properly, and rewrite it so a curious person with no background in what we do gets it in one read. It shouldn’t be dumbed down or stripped of nuance, just super clear.

Responsibilities

• Write campaign copy across channels: web pages, email, social, video scripts, and paid placements
• Work with researchers, fellows, and program leads to translate their work into copy that holds up to their scrutiny and lands with a general audience
• Take briefs from concept to final copy, including headlines, taglines, and CTAs
• Adapt one core idea into many formats without the message drifting
• Protect the integrity of the source material. If a simplification changes the meaning, you flag it and find another way in
• Keep our voice consistent across campaigns while giving each one room to feel distinct

Requirements

• 5+ years writing brand or campaign copy, ideally some of it for mission-driven organizations, research institutions, or brands dealing in complex subject matter
• Proof that you can do the hard version of simplifying: a portfolio piece where the source material was technical or academic and the output was genuinely readable
• Comfort interviewing subject-matter experts and pushing back when the jargon creeps in
• Strong editing instincts. You know the difference between shorter and clearer
• Self-directed. You can run with a brief, manage your own hours, and hit deadlines without hand-holding
• Interest in the issues we work on: AI accountability, privacy, open internet. You don't need to be an expert but being interested helps!

Nice to have

• Experience in advocacy, campaigning, or public-interest communications
• Familiarity with SEO and performance copy basics
• Experience writing for global audiences
• Experience writing exec communications
