Campaign Performance Manager in London

With a history that dates back over 80 years, Starcom is a global communications planning and media leader. We are an agency still grounded in our founding principle that people are at the centre of all we do. Each day, we apply this belief to harness the transformative power of data and technology to inspire and move people and business forward.

Overview: We’re now looking for a Global Campaign Performance Manager to join our Global Data & Analytics team — a role that sits right at the intersection of data, media, and global brand storytelling. This is a fantastic opportunity for someone who loves turning complex, multi‑market media data into meaningful insights that shape future global campaigns — and who enjoys working with one of the world’s most iconic brands.

Responsibilities: As Global Campaign Performance Manager, you’ll be embedded within the global reporting team, partnering closely with central planning and activation teams. Your work will directly influence how global campaigns are optimised, evaluated, and evolved. Key responsibilities include:

• Leading performance reporting for global, centralised campaigns across brand, education, sustainability, gaming, and digital experiences
• Delivering pacing reports, end‑of‑campaign reports, and deep post‑campaign analysis with clear, actionable recommendations
• Supporting mid‑campaign optimisations in collaboration with planning and digital activation teams
• Leading global post‑campaign analysis, integrating multi‑market performance and planning data
• Enriching insights using additional data sources such as brand studies, MMM outputs, search trends, and client‑owned data
• Translating complex media performance into clear narratives for stakeholders with varying levels of media knowledge
• Supporting data QA processes to ensure accuracy, consistency, and robustness of reporting
• Collaborating across global teams to improve reporting standards, processes, and innovation initiatives

Qualifications: We’re looking for someone who is analytically curious, detail‑oriented, and confident working in a fast‑paced global environment. You’ll likely bring:

• Strong understanding of paid media planning, buying, and performance metrics (CPM, CPA, CTR, VTR, ROAS, etc.)
• Experience working with large, cross‑channel datasets and drawing clear “so what?” insights
• Advanced Excel skills (pivot tables, lookups, data manipulation) and strong PowerPoint storytelling ability
• Confidence working with multiple stakeholders across markets and disciplines
• Excellent organisational skills and the ability to manage multiple deadlines with precision
• A proactive, collaborative mindset and genuine enthusiasm for learning and improvement

Nice to have (but not essential):

• Agency experience in a media analytics or performance role
• Experience working in a global or multi‑market context
• Exposure to data visualisation or advanced analytics tools
• Understanding of global media taxonomies or data governance principles
