The Company They are a large, fast-moving retailer with a strong focus on digital innovation. Their teams work collaboratively to improve customer experience through data, technology and continuous optimisation. Experimentation is a key lever in their decision-making process, and they are investing heavily in building a best-in-class testing ecosystem. You will join a supportive environment where learning, growth and cross-functional collaboration are part of everyday work.
The Role In this role, you will: * Promote and embed experimentation best practice across product, engineering and analytics teams. * Support the setup and execution of experiments using approved experimentation platforms. * Advise on client-side and server-side testing, including feature flag approaches. * Validate tracking, data quality and exposure logging alongside analytics teams. * Identify and resolve configuration or tracking issues before launch. * Run experiment readiness checks covering metrics, audiences and implementation quality. * Collaborate with engineering and data teams to improve experimentation tooling. * Contribute to documentation and enablement resources that uplift experimentation maturity.
