• Analyse and present campaign performance, with clear commercial recommendations
• Act as a trusted advisor—confidently challenging client strategies to maximise impact
• Champion Tesco Media products and drive platform adoption
• Support campaign delivery through close collaboration with account and operations teams

• Experience in media sales and/or account management, with a strong track record of meeting targets and delivering customer satisfaction
• Experience in retail media and/or non-endemic categories is a plus
• Passion for Retail Media and a strong understanding of Tesco Media products and services
• Extensive knowledge of brand, performance and digital marketing ecosystems, including key metrics and measurement approaches

• Highly analytical, with strong Excel and PowerPoint skills and experience working with complex datasets to generate actionable insights
• Confident communicator and presenter, able to influence stakeholders at all levels
• Self-motivated, results-driven, and comfortable operating in a fast-paced environment
• A collaborative team player, experienced in working cross-functionally
• Good understanding of the UK media agency landscape
