We're a digital marketing agency that thrives on bold ideas and powerful visuals. At Catalyst Growth, we specialise in UGC ads, static and motion design creatives. We work with fast-growing DTC brands across the world to drive engagement and scale their digital presence.
Some ads get ignored. Some ads stop the scroll, start conversations, and scale brands. Those are the ads that matter and the ads we make. Catalyst is looking for a curious, ambitious Junior Copywriter to join our creative team and learn how high‑performing paid social creative gets made. You'll work alongside Creative Strategists, Designers, and Producers to turn client briefs into ideas that are built to perform across Meta, TikTok, YouTube, and wherever audiences are spending their time next.
This is a role for someone who loves writing, pays attention to the ads they save or click on, and wants to understand why some creative scales while other creative disappears into the feed. You'll learn how to write the hooks that earn attention, the scripts that drive action, and the copy that helps brands grow. Most importantly, you'll learn how performance data turns good creative into great creative.
What you'll be doing
- Turning briefs into creative that performs:
- Work alongside Creative Strategists and Designers to respond to client briefs from concept through to delivery.
- Help develop ideas that balance creativity with commercial objectives.
- Contribute fresh angles, new hooks, and copy‑led ideas during brainstorms and creative sessions.
- Partner with Designers to make sure words and visuals work together, particularly in static formats where every word earns its place.
- Learning the craft of performance copywriting:
- Write across a range of formats including hooks, UGC scripts, headlines, CTAs, statics, and supporting creative assets.
- Learn what makes people stop scrolling, engage, and convert.
- Build an understanding of each client's tone of voice and apply it consistently across every output.
- Adapt copy for different platforms, audiences, and placements across paid social.
- Testing, learning, and improving:
- Use creative performance data and testing feedback to improve your work over time.
- Learn how winning ads are built through iteration rather than guesswork.
- Treat every result as a learning opportunity and every test as a chance to uncover the next winning angle.
- Develop an instinct for spotting patterns, trends, and opportunities before they become obvious.
What we're looking for
- Copywriting experience through previous roles, internships, freelance work, or a portfolio you're proud of.
- A genuine interest in advertising, paid social, and performance creative.
- A collaborative, team-first mindset and the confidence to share ideas early and often.
- Strong attention to detail and the ability to self‑edit and deliver polished work under tight deadlines.
- Someone who enjoys moving quickly, learning continuously, and improving with every round of feedback.
We're based in London and operate a hybrid working model - 2 days in our Elephant & Castle office.
