Digital User Experience Lead (CRO)

Eucalyptus is on a mission to make good health last a lifetime. Euc is the company behind Juniper, one of the world's largest weight-management programs combining GLP-1 medication with personalised nutrition, movement support, and clinician-led care. We're looking for a Digital User Experience Lead (CRO) to own a structured, always-on programme of experimentation across key digital surfaces: landing pages, assessment flows, activation, and onboarding, with ambition to expand into post sales and lifecycle touchpoints.

Responsibilities

Own a structured, always-on programme of experimentation across key digital surfaces including landing pages, assessment flows, activation, and onboarding; Turn data and insight into sharper hypotheses by combining funnel analytics, behavioural data, session recordings, patient research, and support themes; Run structured discovery each quarter that changes at least one roadmap priority; Write read-outs that go beyond the result; Build and own a structured experimentation programme with a clear hypothesis and experimentation framework; Sequence experiments deliberately and test the riskiest hypotheses first; Maintain a clear, always-current view of what you're testing, why, and what you expect to learn; Ensure every test maps back to a strategic question about the patient experience; Write rigorous briefs including hypothesis, primary metric, success criteria, sample size, and expected run time; Understand statistical vs practical significance and never call a test early; Update the roadmap after every experiment based on learnings; Build a compounding library of knowledge about what works on our surfaces; Collaborate with design, product managers, growth marketing, and clinical to move tests from brief to launch; Flag dependencies and risks before they become blockers.

Requirements

You think of experiments as a way to validate your thinking, not just a test; You have a framework for how you decide what to test, in what order, and why; You are statistically literate and uncompromising, understanding statistical power, sample size, significance, and confidence intervals; You have told stakeholders 'we can't call this yet' and held the line; You know that a poorly run experiment is worse than no experiment at all; You are a systematic hypothesis builder who knows what question you are answering, what you expect to happen, and what you will conclude if the result goes either way; You synthesize insight across sources, combining quantitative funnel data with qualitative signals such as user research, session recordings, and support themes; You are obsessed with the 'so what'; You own outcomes, not just execution, tracking metrics post-launch and diagnosing what happened; You bring scientific rigour to run experiments and strategic instinct to know which experiments are worth running.
