How would you like to optimize some of the world’s most successful eCommerce stores, SaaS products, and mobile apps across the US, Europe, and beyond?

In this role, you will lead a cross-functional group - project manager, data engineer, analyst, UX researcher, UX/UI designer, copywriter, developer, and QA - to deliver measurable improvements in conversion rate (CvR) and average revenue per user (ARPU) for our clients. This is an ownership role where you’ll drive high-impact experiments and growth initiatives for global brands.

Responsibilities

• Lead a cross-functional team in ideating and formulating CRO hypotheses that improve funnel performance and revenue metrics.
• Prototype optimized funnel experiences in Figma as guidance for UX/UI designers.
• Define developer tasks for A/B tests, monitor experiment setup, and coordinate with analysts to report results.
• Conduct statistical and causal analysis to ensure results are significant, valid, and attributable to UX/UI improvements.
• Present experiment results to clients with clear insights, ensuring full buy-in and confidence in the causal link between the changes and the uplift achieved.

Requirements

• Advanced proficiency in UX/UI principles for crafting robust CRO hypotheses and translating them into high-quality Figma prototypes.
• Proven experience creating data-driven, research-based CRO hypotheses, supported by case studies and experiment results.
