We help employers attract and engage the people who'll make their business thrive. As a Paid Media Strategist, you'll play a central role in making that happen, shaping how employer brands show up in the world, how people discover real job opportunities, and how media investment turns into meaningful results.

This is a hands-on, end-to-end role. You'll lead media strategy, stay close to the platforms, own performance for your clients, and bring clarity and confidence to how strategy and results are communicated.

You'll work across channels, including Google, Meta, LinkedIn, TikTok and programmatic, sometimes building a full-funnel strategy in Excel, sometimes optimising in-platform, sometimes standing in front of clients explaining what's working, what isn't, and what should happen next.

You'll collaborate closely with Client Services, Digital Strategy, Creative and Data Ops. While there may be junior or specialist support at times, you are accountable for the thinking, the delivery and the client experience.

If you'd been here recently, you might have led a paid media strategy for McDonald's restaurant recruitment, tested new TikTok formats for Specsavers, or used performance data to help Royal Mail attract thousands of seasonal workers and then presented the story behind the results.

What you'll do

Own media strategy and performance for your clients, from brief and planning through to activation, optimisation, reporting and presentation.
Develop and confidently sell in big media ideas, from global CTV strategies to sophisticated retargeting and sequencing approaches using clear rationale, insight and performance logic to bring clients with you.
Plan and manage multi-channel paid campaigns across platforms such as Google, Meta, LinkedIn, TikTok and programmatic platforms.
Build structured media plans in Excel, including budgets, pacing and forecasting across roles, markets and funnel stages.
Create and present engaging media strategy and performance decks shaping the narrative, rationale and recommendations that guide client decisions.
Work directly in-platform, building, activating, optimising and QA-ing campaigns when required.
Analyse campaign performance and produce reports that explain not just what happened, but why and what to do next.
Be an active part of client conversations: joining WIPs with Client Services, presenting plans and results, handling challenge and confidently selling in ideas and recommendations.
Stay curious about platform updates and enhancements and understand how new formats and capabilities can be applied in a meaningful way for clients.
Research, test, and evaluate new platforms, formats and approaches that could strengthen campaign performance.
Collaborate closely with creative, research, data, UX and development teams to ensure media aligns with messaging, candidate journeys and measurement.
Support and mentor others in the media team, sharing knowledge and helping raise the standard of planning, activation and thinking.
Contribute to improving how we plan, buy and measure media at ThirtyThree from better templates and tools to smarter, more joined-up processes.

What we're looking for

You have strong hands-on experience across paid media platforms. Platform certifications (Google, Meta, LinkedIn, TikTok and ideally StackAdapt or DV360) are expected. If you don't already have them, you'll be supported to complete them once you join.
Strong Excel skills and confidence in building structured plans and forecasts.
Comfortable presenting media strategy and performance, with the ability to clearly explain the why behind decisions to both digital and non-digital audiences.
Working knowledge of campaign tracking and measurement (UTMs, tagging, GA4 awareness).
Solid understanding of performance metrics (CTR, CPC, CVR, frequency, drop-off) and how to use them diagnostically.
Up-to-date with media trends and technologies. Interested in innovation, but focused on effectiveness.
Experience collaborating with creative, strategy, client service and technical teams in a joined-up way. To make sure the media connects seamlessly with campaign messaging and objectives.
You understand how paid media connects to other parts of the digital ecosystem, including SEO, UX, organic social, content and tracking and can factor these into your media thinking and performance diagnosis. You don't need to be a specialist in these areas, but you know when they're influencing results and how to work with the right teams to improve performance.
Be an active part of client conversations, joining WIPs with Client Services, presenting media strategies and reports, and confidently taking clients through plans, performance and recommendations
A genuine interest in how digital media helps people find jobs and helps employers find the right people.
