What the job involves
- Your mission is to own the full loop of Conversion Rate Optimization at iubenda, from hypothesis to shipped test to measurable revenue impact, across our websites and product surfaces, as a hands-on individual contributor: designing and running every A/B test with statistical rigor, building and maintaining the tracking that makes results trustworthy, and turning data into clear, actionable recommendations
- You own how tests get built, run, and measured. The Monetization Principal, Marketing, and Product own what gets tested and why on their respective surfaces, and bring their initiatives to your queue. You will report to the Director of Growth, working closely with the Revenue Business Analyst, the Monetization Principal, Product, Engineering, and Marketing. This role sits at the center of iubenda's experimentation engine
