About the role: The Paid Media Executive (Interim) will play a key role in executing marketing campaigns across digital performance channels, including paid search, paid social, programmatic and display, for our client, an internationally recognised B2B organisation. The Digital Centre of Excellence (DCoE) within the client’s pharmaceutical practice is appointed to drive digital best practices, develop digital channel strategies, and grow audience engagement across all digital touchpoints. In this role, you will support the Digital Marketing Manager by executing, optimising, and reporting on marketing campaigns, working collaboratively with marketing and sales teams and external agencies. You’ll be responsible for managing key digital marketing channels across Google Ads, Meta, LinkedIn and programmatic platforms. You’ll work closely with the Digital Marketing Manager and the wider marketing team, and collaborate with the client’s external agencies and partners to ensure seamless campaign execution. Beyond day‑to‑day delivery, you’ll bring a curious, improvement‑oriented mindset - contributing ideas and learnings to help evolve how paid media is done within the team.

What you will be doing:

• Execute and optimise acquisition campaigns across paid social, paid search, PPC, programmatic and display, supporting wider growth objectives.
• Own the day‑to‑day setup, management and optimisation of performance campaigns, with a strong focus on ROI, CPA and lead quality.
• Support the development of channel strategies by providing insights, testing ideas, and feeding performance learnings back to the Digital Marketing Manager.
• Monitor performance against KPIs, flagging risks or opportunities early and recommending tactical improvements.
• Assist with budget pacing and spend optimisation across channels.
• Track and optimise campaign performance against lead generation, pipeline and revenue objectives, not just media metrics.
• Conduct campaign analysis and reporting, turning data into clear, practical insights.
• Work closely with Creative, Sales, and Events teams to ensure campaigns are aligned with messaging, audiences, and objectives.
• Collaborate with internal stakeholders and external agencies to ensure campaigns are delivered accurately and on time.
• Run post‑campaign analysis, develop test‑and‑learn hypotheses, and continuously improve channel efficiency.
• Stay curious about new platforms, formats, and features, contributing ideas and learnings to the wider team.
• Develop and execute structured testing plans across audiences, creatives, bidding strategies and landing page experiences.

What you need to be great in this role:

• Hands‑on experience building and managing paid campaigns across paid search and paid social.
• Proven experience managing paid campaigns across Meta and Google as a minimum; LinkedIn experience is a plus.
• Strong analytical mindset — comfortable working with data and able to turn numbers into actions.
• Experience working with agencies or external partners is advantageous.
• Able to work independently on execution while knowing when to elevate or seek input.
• Proactive communicator — able to explain performance simply and confidently, even when bringing risks and concerns to the table.
• B2B experience is essential; pharmaceutical industry or events marketing experience is a bonus.
• Familiarity with analytics and martech tools (GA, LinkedIn/Meta analytics, dashboards) is advantageous.
• Comfortable using AI‑powered tools to improve efficiency across campaign planning, audience research, reporting and optimisation workflows.
