• Input into the design and development of data‑driven attribution (DDA) and media mix modelling (MMM) to build an accurate picture of touchpoint value contribution and media planning
• You’ll have a passion to learn, will want to make a positive difference and be excited about how we can grow
• You’ll want to think about interesting, difficult problems, share your thoughts and make recommendations – and be able to think creatively, and explore different routes to solving problems
• You’ll be a great communicator, able to effectively convey messages to our marketing partners and senior stakeholders within the business – and you enjoy working collaboratively with associates from across the business. You’ll explain technical concepts in an easy to understand way
• You’ll be able to take ownership of your area, and work with a proactive mindset – taking the initiative to identify and drive opportunities, and prioritising effectively across multiple projects and deliverables
• You’ll have good experience in Adtech, like Google Analytics 4 (GA4), Google Tag Manager (GTM), Campaign Manager 360 (CM360), Tealium, Snowflake, Tableau, Supermetrics and more
• You’ll also have experience querying databases – ideally using SQL, or a similar language
• You’ll be proficient working with numbers and data, have strong reasoning skills, and be able to critically analyse data outputs – extracting insights and bringing these to life with clear visualisations
