We are looking for an analytical and curious Senior Marketing Analyst to join the Marketing Analytics arm of our Data team. Our aim is to drive sustainable, high-quality growth by helping marketing teams understand what’s working, what’s not, and where to invest next. In this role, you will play a critical part in shaping how we measure marketing effectiveness.

Key responsibilities:

• Partner closely with channel leads to define learning agendas, frame the right questions, and translate insight into clear, actionable recommendations.
• Design and deliver across paid media and the wider marketing mix, including campaign performance, incrementality, efficiency, and diminishing returns.
• Integrate outputs from multiple measurement approaches such as experiments, cohort analysis, attribution signals, MMM into coherent, decision-led narratives for senior stakeholders.
• Act as a subject-matter expert on acquisition KPIs and measurement strategy, advising on trade-offs between short-term performance and long-term value creation.
• Support the day-to-day measurement needs of the New Member Revenue team, providing guidance on analysis design, interpretation, prioritisation, and next steps.
• Build and promote efficient, scalable acquisition measurement processes that reduce duplicated work and increase confidence in insights across teams.
• Collaborate closely with Marketing, Product, Finance, and Data partners to ensure acquisition measurement aligns with business priorities and informs planning and investment decisions.

Experience and competencies:

• Significant experience in marketing, media, or growth analytics within a digital, marketplace, subscription, or consumer technology business.
• Strong understanding of paid media performance and buying mechanics, alongside broader acquisition levers including brand, organic, and lifecycle effects.
• Hands-on experience with effectiveness and incrementality measurement approaches such as lift studies, controlled experiments, MMM, and A/B testing.
• Proven ability to synthesise complex, multi-source data into clear insights that influence decisions at senior levels.
• Comfortable operating in ambiguity, able to apply sound judgement when data is incomplete, noisy, or contradictory.
• Flexible and open-minded, able to thrive in a fast-moving, evolving environment.
• Comfortable operating as a senior individual contributor, influencing without authority and partnering closely with leadership teams.
• Clear, confident communicator with strong written and verbal presentation skills.

Tools and technical skills:

• Strong working knowledge of SQL and experience analysing large, complex datasets.
• Familiarity with analytical tools and languages such as Python or R.
• Experience working with marketing and experimentation data from major digital platforms and internal data warehouses (we use Databricks).
