Senior Paid Media Specialist

The job

You’d lead paid media strategy and delivery on some of our more complex, higher-value client accounts, reporting to our Head of Paid Media. You’d work largely independently, with regular client contact, and mentor the Specialists and Executives in the team.

Our clients are a mix of ecommerce, beauty, B2B and financial services brands, and our paid media team works alongside specialists in SEO, Content, Digital PR and Social. Your job is to make sure the paid search and paid social on your accounts is well built, tightly managed and clearly tied to what each client needs from it (revenue, leads and a strong return on their spend).

What you’d be doing

You’d lead the paid media strategy and delivery on your accounts. That means planning, building and optimising campaigns across Google Ads, Microsoft Ads, Meta and LinkedIn, managing budgets, pacing and bidding to hit each client’s targets, and reading the performance data to decide what to change. You’d report
back on what changed, why, and what we’re doing next, and with support, take a growing lead in weekly client calls and QSRs.

You’d also:

• Run regular audits and structured A/B tests across your accounts, and turn what you learn into recommendations for your own clients and the wider team.
• Keep on top of how the ad platforms are changing (new campaign types, automation, tracking and attribution) and spot what matters for our clients early.
• Mentor, coach and peer review our Specialists and Executives, and help build the templates, processes and quality checks that make good work repeatable.
• Share what you know inside and outside Liberty (lunch and learns, blogs, webinars) and build a reputation for your expertise.
• Bring channel insight and evidence to pitches, renewals and proposals, and spot where a client would benefit from more of what we do.
• Work with Client Services, SEO, Content, Digital PR and Social so paid media is part of each client’s wider plan.

Who we think this is

• You’ve worked as part of a paid media team in an agency and been judged on client outcomes (KPIs, account performance and business impact).
• You’ve probably been at an agency of 20 to 100+ people with SEO, content, digital PR, paid media and social on the services list, or a specialist paid media agency of a similar size
• You’ve led the strategy and delivery on multiple paid search and paid social accounts at once, and grown the return they deliver.
• You’re hands-on in the platforms (Google Ads, Microsoft Ads, Meta, LinkedIn) and confident managing budgets, pacing and bidding.
• You hold Google Ads certifications, or you’re ready to gain three within your first six months
• You’re comfortable talking to clients regularly, explaining your results and recommendations and answering questions on your approach.
• You can talk about paid media performance in commercial terms (revenue, ROAS, cost per acquisition) as well as clicks and impressions.
• You’ve worked in at least one of ecommerce, B2B lead generation, beauty and wellbeing, or financial services, either client side or agency.
