This is a highly collaborative, data-driven role for someone who is naturally curious and proactive in finding opportunities to improve commercial performance.

Core Responsibilities
- Lead one of our optimisation testing programs. Develop testing strategies and manage A/B and multivariate tests end-to-end, from hypothesis and planning through execution, performance review and recommendations across LEGO.com.
- Identify commercial opportunities. Proactively use data, shopper behaviour and performance insights to identify opportunities to improve conversion, engagement and commercial sales performance, turning ideas into compelling test hypotheses.
- Turn data into action. Analyse test results using tools such as Adobe Analytics and Optimizely, alongside tools such as Quantum Metric, to understand shopper behaviour and conversion journeys and translate findings into clear, actionable recommendations.
- Influence across a complex stakeholder landscape. Work closely with Product, Digital Insights, Research, Marketing, Loyalty, Personalisation, Legal and other business teams to align priorities, resolve conflicts and influence decisions on what to test and which experiences or messages to prioritise.
- Build the future of testing. Partner with Product teams to improve the technical capabilities of optimisation testing, while helping to evolve testing best practices and demonstrate the commercial value of experimentation across the organisation.
Do you have what it takes?
- Testing & optimisation expertise. Strong experience with A/B and multivariate testing methodologies, ideally across ecommerce, websites and/or CRM, with experience using optimisation tools such as Optimizely.
- Data-driven commercial mindset. Strong analytical capability and experience using data to uncover opportunities, assess performance and make commercially focused recommendations. Experience with Adobe Analytics is preferred, with Google Analytics also valuable.
- Insight & storytelling. The ability to translate complex test results and shopper insights into a compelling narrative, clearly explaining what the data means and recommending what the business should do next.
- Stakeholder influence. Experienced in influencing and negotiating with a broad and senior stakeholder group, confidently navigating competing priorities and bringing teams together around the right customer and commercial outcome.
- Proactive problem solver. Curious, creative and highly motivated to find opportunities, with a structured and pragmatic approach to managing multiple tests and initiatives in a complex, fast-moving organisation.
