We are looking for a CRO & Experience Specialist to become the architect of our e-commerce (Shopify) growth.
Reporting to the Head of E-commerce, you will own the scientific process of turning traffic into revenue. You won’t just “run tests”; you will own the entire experimentation lifecycle—from data deep diving and user psychology to “no-code” implementation on Shopify.
Responsibilities:
1. A/B Testing strategy & roadmap ownership
Scientific prioritization: Own the testing backlog. You use structured frameworks (ICE/PXL) to prioritize opportunities, ensuring we focus on high-impact wins rather than random ideas.
Hypothesis generation: Translate business goals (e.g., “Increase cross-sell,” “Reduce checkout abandonment”) into testable user scenarios based on behavioral psychology and data.
2. “No-Code” implementation & visual merchandising
Shopify theme mastery: You are a master of the Shopify Customizer. You leverage our existing theme sections and templates to build high-converting page layouts without needing a developer.
Copywriting & logic: You understand that design is often about the words and the flow. You write persuasive headers, value propositions, and CTAs that fit the layout and drive conversion.
Rapid prototyping: you sketch quick wireframes, then build them directly in the Shopify editor for speed and efficiency.
3. Advanced data analysis
Deep dive into GA4, Shopify reports, and Heatmaps (Clarity/LogRocket) to diagnose friction, like why users are dropping off at different funnel steps.
Statistical rigor: You are the guardian of data integrity. You determine sample sizes and ensure we never call a test “early” based on false positives.
4. Test setup & operations
Execution: Set up experiments in our testing platform (VWO) with precision.
Collaboration: Work hand-in-hand with our Operations Manager & QA to ensure complex tests are bug-free before launch and effectively handed over for permanent implementation.
5. Lead gen strategy:
Experience: 4-6 years in CRO, E-commerce, Growth, or Site Merchandising. You have a proven track record of lifting conversion rates.
The “Builder” mindset: You are comfortable building pages yourself. You prefer a page that converts at 5% over a page that looks “pretty” but converts at 2%.
Tech Stack: Deep proficiency in Shopify, GA4, and A/B testing tools (VWO, Convert, or similar).
Data-Driven: You don’t get attached to your ideas; you let the data decide. You are comfortable analyzing segments and cohorts to find the truth.
Bonus: Familiarity with HTML/CSS (to tweak spacing/colors) is a plus, but not required.
Passion for the healthtech industry is appreciated!
