• Using Adobe Analytics, Optimizely, and Contentsquare to inform, track, and measure experiments

• Translating test results into clear commercial recommendations

• Championing experimentation best practices across client teams

What we're looking for

• Proven experience in experimentation (not just CRO) within an agency or consultancy environment

• Strong commercial acumen - ability to link experimentation outcomes directly to revenue growth

• Deep expertise in Adobe Analytics

• Hands-on experience with Optimizely and Contentsquare

• Exceptional communication and stakeholder management skills
