WHO YOU'LL WORK WITH

Join a global company defined by innovation, collaboration, and professional growth. Our culture blends start-up energy with the maturity of a publicly listed business. We reward achievement and recognize the impact of our people.

As Senior Marketing Analyst, you’ll be a pivotal member of the Marketing Analytics & Insights Team, reporting to the Head of Marketing Analytics and working closely with our Commercial Growth teams. You’ll collaborate across Technology, Product and Marketing to drive business objectives.

A core responsibility for this role is to lead the analytics underpinning our “Marketing Mix Profitability & Allocation” initiative. You will play a key part in building the capability to identify our most and least profitable customer acquisition sources and optimally allocate marketing spend across web and social channels.

WHAT YOU'LL DO

Marketing Mix Profitability & Allocation :

• Lead the strategic allocation of marketing budgets by applying data-driven methodologies to maximize return on investment (ROI) across channels.
• Utilize advanced analytics, attribution modeling, and customer lifetime value (CLV) analysis to identify high-performing segments, optimize spend, and ensure resources are directed toward the most impactful campaigns and audiences.
• Champion incrementality as the gold standard of marketing measurement—design and interpret experiments to determine the true causal impact of marketing activities, ensuring budget decisions are based on what genuinely drives incremental growth.
• Continuously monitor market trends, campaign performance, and evolving customer behaviors to inform real-time budget adjustments, balancing proven tactics with innovative and experimental initiatives.
• Collaborate with cross-functional teams to align marketing investments with business objectives, leveraging insights to drive measurable growth, efficiency, and accountability in all marketing activities.
