This is an exciting opportunity to join a data‑driven digital organisation where experimentation plays a central role in shaping product decisions. If you are passionate about A/B testing, tooling, and helping teams run high‑quality experiments at scale, this role gives you the platform to make a real impact.
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.
Your Skills and Experience
You will bring:
* Strong commercial experience building experiments using HTML, JavaScript and CSS.
* Hands‑on experience with platforms such as Optimizely, AB Tasty, Monetate or Dynamic Yield.
* A strong understanding of A/B testing concepts and feature flag workflows.
* A focus on data quality, tracking and experimentation governance.
* The ability to troubleshoot technical issues and communicate effectively with cross‑functional teams.
* Experience in ecommerce or digital product environments is beneficial but not essential.
What They Offer
* Competitive salary depending on experience.
* A fast‑paced environment with clear opportunities for progression.
* Access to learning resources, wellbeing support and internal development programmes.
* The chance to contribute to a high‑visibility experimentation function with real impact on product and customer experience.
