We’re looking for an Experimentation Engineer to help shape how customers experience our website. Experimentation is central to how we optimise performance, and this role sits at the heart of turning insight and ideas into live, impactful tests.
You’ll take agreed test plans and bring them to life by building A/B experiments that reach real customers and deliver measurable improvements to both experience and commercial results.
* Your work goes live fast and directly influences customer behaviour
* Strong leadership buy‑in, experimentation is recognised as a key driver of growth
* A hands‑on role combining coding, customer thinking and commercial impact
* Exposure to a wide range of teams including Trading, Pricing, CRO, Analytics and IT
What you’ll do
* Translate test plans into robust, production‑ready A/B tests
* Use Adobe Target (or similar tools such as Optimizely, AB Tasty or Dynamic Yield)
* Apply a customer‑first mindset while improving conversion and performance
* Collaborate closely with technical and non‑technical stakeholders
What you’ll bring
* Experience building experiments in Adobe Target or similar platforms
* Strong QA discipline and attention to detail
* Confidence communicating with stakeholders - this role is not “code‑only”
* Curiosity, problem‑solving and a desire to see your work make a real impact
You’ll join a forward‑thinking team that embraces innovation, experimentation, and continuous improvement. Your work will have a direct and visible impact on business results, in a role where technical skill and analytical thinking truly shine.
