Job description

Hi, we’re Phiture — the mobile growth consultancy working with the teams behind leading apps like Adobe, Headspace, and LEGO. We’re setting the standard for growth in the brave new digital world, and we need great people to join our global team!

WHAT TO EXPECT:

We're looking for a sharp, versatile Senior Copywriter to own copy across some of Phiture's biggest accounts, including one of Europe’s biggest mobile gaming companies, the USA’s largest retailer, a fintech that keeps families connected across borders, and a fast-growing productivity app.

You'll join a close-knit creative pod, working side by side with our Creative Lead, designers and Growth Consultants. Together, you'll turn briefs, audience insights and testing hypotheses into conversion-focused copy that reaches millions of users in app stores around the world.

This isn't copywriting in a vacuum. You'll see how your messaging performs, learn from every test and use those insights to make the next round sharper. You'll switch between very different brands, tones and formats, often within tight character limits and on deadlines tied to larger experiments. It's a role for a writer who cares as much about why copy works as how it sounds, and who wants to grow into ASO, experimentation and creative strategy.

WHAT YOU'LL DO:

• Own copy delivery across your assigned accounts, from brief interpretation through to final QA on production and market localisation
• Translate creative briefs, audience insights and testing hypotheses into clear, conversion-focused copy, and ask the right questions when context or objectives are missing
• Write across a range of formats, including:
  • App store metadata, screenshot captions and in-app events
  • Promotional content, storyboards and CRM campaigns
• Build deep knowledge of each client's brand, products, features and audiences, understanding not just what we're promoting, but why
• Switch confidently between distinct brand voices, formats and markets, keeping each brand's identity intact while leaving room for creative testing
• Partner closely with designers so that copy and visuals work towards the same objective
• Write English source copy that translates well, and adapt messaging for different English-speaking markets
• Use creative testing and performance results to shape your recommendations and bring new ideas to the table
• Present and explain your creative rationale in meetings, alongside the Creative Lead
• Brief, guide and review freelance copywriters when the workload calls for it
• Carry client feedback, brand preferences and past learnings into every new piece of work
• Run copy QA and proofreading, including checking final designs for accuracy, localisation and consistency
• Plan your own workload and capacity, flagging risks early so copy never holds up design, testing or launches
• Use AI tools thoughtfully to work smarter, with the judgement to critically edit what they produce

WHAT YOU'LL NEED:

• Native-level English copywriting ability, with excellent grammar, editorial skills and exceptional attention to detail
• Proven experience in a senior copywriting role, writing compelling digital copy across different formats and brands
• Strategic and commercial thinking: you can find the real user benefit in a brief and explain why your copy will work, not just why it sounds good
• A strong portfolio that shows range across brand voices and clear, benefit-led messaging
• Experience managing multiple projects in a fast-paced, deadline-driven environment, with full ownership of quality, priorities and delivery
• A collaborative mindset: you enjoy working closely with designers and strategists, and respond constructively to feedback
• Confident communication with clients and internal stakeholders at all levels
• Experience in a creative or digital agency, ideally in mobile, performance or growth marketing
• Experience with ASO, SEO, UX or performance copywriting is a plus, but not essential, we'll teach you the ASO side. What matters most is strong craft, curiosity and a real interest in how ASO works beyond the copy itself
• Curiosity about products, audiences and the data behind them

We encourage all qualified individuals to apply, regardless of their age, gender identity, ethnicity, sexual orientation, disability status, or religion. We celebrate diversity and are excited about building teams that represent a variety of backgrounds, perspectives, and skills. All employment decisions are based on qualifications, merit, and business needs.
