• Partner with CRM teams to evaluate lifecycle marketing performance, segmentation, and audience strategy.
• Work with marketing and media teams to test, measure, and optimise channel mix and budget allocation.
• Support advanced attribution modelling and MMM (Marketing Mix Modelling) initiatives where applicable.
• Translate complex data into simple insights and recommendations for non-technical stakeholders.
• Identify marginal gains and performance levers across channels and customer touchpoints.
• Ensure data quality, consistency, and integrity across all marketing and CRM systems.
• Monitor marketing KPIs on a daily/weekly basis and proactively flag performance issues or opportunities.

Skills:

• Strong experience in marketing analytics, ideally in a fast-paced eCommerce, retail environment.
• Deep understanding of multi-channel marketing performance and platforms – across paid search (Google), paid social (Meta), display, affiliates (AWIN), SEO, and CRM.
• Advanced proficiency in Excel/Google Sheets and analytics tools such as Google Analytics (GA4), Looker Studio, Tableau, or Power BI.
• Experience with data extraction using SQL or familiarity with data warehouses (BigQuery, Snowflake).
• Strong knowledge of attribution models and customer lifecycle metrics (CAC, LTV, churn, etc.).
• High attention to detail, accuracy, and a passion for uncovering insights in complex datasets.
• Ability to clearly communicate insights to stakeholders at all levels and influence marketing strategy.
• Comfortable managing multiple projects simultaneously and working with both technical and creative teams.
