Experimentation Manager- CRO

Experimentation Manager (Contract) Initial 4–6 Month Contract

Remote | UK

Ready to make a measurable impact from day one?

If you love turning customer insights into commercial results through experimentation, this could be the contract you've been waiting for.

We're working exclusively with a fast-growing digital consultancy supporting multiple international D2C brands, including one of the UK's best-known subscription brands in the pet space. Following a major ecommerce transformation, they're investing heavily in experimentation to improve customer experience, increase conversion, and drive growth.

They're looking for an experienced Experimentation Manager to join on an initial 4–6 month contract and help establish a robust experimentation programme from the ground up.

What you'll be doing

You'll partner closely with the UX Lead and development team, taking ownership of the end-to-end experimentation process across the flagship D2C brand.

This is a genuinely hands-on role where you'll be expected to:

• Build, launch and QA A/B and multivariate tests
• Develop data-led hypotheses using behavioural analytics and customer insights
• Analyse experiment performance and present clear recommendations
• Work closely with developers and designers to implement and iterate tests quickly
• Help build an experimentation framework that can be rolled out across multiple brands
• Document learnings and create a knowledge base for future optimisation

Initially, your focus will be on a single brand where you'll have the autonomy to move quickly, test often and deliver measurable improvements.

What we're looking for

We're looking for someone who enjoys getting stuck in and has a proven track record of delivering successful experimentation programmes.

You'll ideally have:

• Around 3+ years' experience in CRO or experimentation
• Strong experience running A/B and multivariate tests end to end
• Experience using tools such as GA4, FullStory or similar behavioural analytics platforms
• A solid understanding of statistical significance and experiment analysis
• Experience within ecommerce, D2C or another commercially focused digital environment
• Working knowledge of HTML, CSS and JavaScript to support simple test builds and QA
• Excellent communication skills and the confidence to work with cross-functional teams

Whether you've built your experience in-house or within an agency environment, we'd love to hear from you.

Why join?

This is an opportunity to make a visible impact on a high-profile D2C subscription brand while working alongside an experienced UX leader who is passionate about building a best-in-class experimentation function.

You'll have the freedom to move quickly, test new ideas, influence customer experience, and see the commercial impact of your work.

While the contract is initially for 4–6 months, there is genuine potential for extension or a permanent opportunity if the role proves successful.
