Creative & Testing

• Creative is a major part of how we approach performance at Twenty-Fifth Media. You’ll be expected to understand not only what looks good, but what makes consumers stop, engage and buy.
• You will:
  • Analyse creative performance and identify winning hooks, formats, messaging and concepts
  • Understand the role of UGC, creator-led content, product demonstrations, tutorials, reviews and social proof within beauty advertising
  • Identify creative fatigue and opportunities for new testing
  • Provide clear, data-led creative recommendations to clients and the wider team
  • Brief the creative assets needed to improve and scale performance
  • Build structured creative testing frameworks and use learnings to shape future campaigns

Reporting & Client Management

• Own weekly and monthly reporting across your portfolio of accounts
• Turn performance data into clear insights, recommendations and next steps
• Lead regular client calls and performance reviews
• Communicate proactively around performance, opportunities, challenges and upcoming activity
• Help clients understand not only what happened, but why it happened and what we’re doing next
• Build strong, trusted relationships with clients and act as a strategic extension of their internal team
• Work closely with the wider Twenty-Fifth Media team to align paid media with creative, TikTok Shop, affiliate and wider brand activity

What We’re Looking For

We’re looking for someone who can confidently step into the role and take ownership of accounts from day one.

You should have:

• Strong hands-on experience managing Meta Ads
• Strong hands-on experience managing Google Ads
• Proven experience managing paid media for e-commerce brands
• A strong understanding of the beauty, wellness and consumer landscape
• Experience working with and scaling meaningful monthly advertising budgets
• Strong understanding of ROAS, CPA/CAC, CTR, CVR, AOV and other core e-commerce metrics
• Experience across Google Search, Shopping and Performance Max
• Strong knowledge of GA4 and paid media tracking and attribution
• Experience building and executing testing and optimisation strategies
• Strong analytical skills and confidence interpreting data to make commercial decisions
• A strong understanding of performance creative and what makes an ad convert
• Confidence communicating directly with clients and presenting performance
• Excellent written and verbal communication skills
• Strong organisation, attention to detail and the ability to manage multiple accounts and priorities simultaneously

Agency experience is highly desirable.

Previous experience working with beauty, skincare, cosmetics, haircare, wellness, fashion or consumer e-commerce brands would be a strong advantage.

You’ll Be a Great Fit If...

• You’re commercially minded and care about the client’s overall growth, rather than simply managing campaigns.

• You’re naturally proactive. If performance drops, you investigate why. If something is working, you look for ways to scale it. If an account needs new creative, you identify it and communicate it before it becomes a problem.

• You understand that creative and media go hand in hand, particularly within beauty, and you’re comfortable giving clear direction on what should be tested next.

• You’re also comfortable working in a fast-moving agency environment, managing multiple priorities and collaborating closely with a small, ambitious team.

Above all, you’re someone we can trust to take ownership, communicate clearly and keep our clients moving forward.
