ABOUT LADDER.IO
Ladder is an adaptive growth agency combining exceptional marketers, world-class creatives and AI-powered workflows to help ambitious brands grow.
Our teams bring together strategy, creative, paid media and technology to continuously test, learn and improve marketing performance. We believe AI makes talented people more effective by giving them better context, more room to explore ideas and faster ways to execute.
We’re looking for a Marketing Copywriter to support our strategy, creative and paid media teams across a busy period of client work. You’ll turn ideas, insights and briefs into clear, compelling copy that sounds right for each brand and gives its audience a reason to act.
THE ROLE
You’ll write and refine copy across a varied mix of clients, audiences and formats, including:
- Landing pages and websites
- Meta and Google ads
- Email campaigns
- Blog articles and LinkedIn posts
- Case studies and team profiles
- Marketing presentations and content briefs
Working closely with strategists, designers and paid media specialists, you’ll help translate marketing strategy into strong messaging, develop different hooks and angles, and improve work through feedback.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
This is an AI-enabled writing role. We use tools such as ChatGPT, Claude and Gemini for research, ideation, drafting and editing. We’re looking for someone who knows how to get useful work from these tools and has the writing ability and judgement to make the final output excellent.
You’ll be responsible for checking facts, questioning weak messaging and making sure every piece feels specific to the brand and audience.

Essential:
- Full-time availability for an initial 1–3 month contract
- Previous copywriting experience, with examples of your work
- Excellent English writing skills, with native-level fluency, strong grammar and close attention to detail
- The ability to write clear, persuasive copy and adapt your tone across brands, audiences and channels

- The ability to follow a brief, brand guidelines and tone of voice requirements
