How to Apply for Conversation Rate Optimisation Specialist - French fluent 🇫🇷

at Paradox

🏢 About Paradox

Paradox is building an advanced ecosystem in human transformation that uniquely combines behavioral science, technology, and AI to help people defy their limits. Unlike traditional companies, they focus on rewiring systems rather than just testing surface-level changes, creating measurable impact on how millions grow and learn.

About This Role

As a French-fluent CRO Specialist at Paradox, you'll be hands-on in ideating, designing, copying, and launching experiments directly—not just advising. This role involves transforming data into structured experimentation roadmaps that shape user behavior and deliver measurable business outcomes within their human transformation ecosystem.

💡 A Day in the Life

A typical day involves analyzing funnel data in GA4 or Mixpanel to identify bottlenecks, using AI tools to generate hypotheses, designing and copying experiment variants in AB Tasty/VWO, and collaborating with teams to launch tests that rewire user behavior systems. You'll balance data analysis with creative experimentation design focused on human transformation metrics.

  • A Behavioral Strategist fluent in French who mixes cognitive psychology, UX, and persuasion frameworks to design converting experiences
  • Hands-on practitioner skilled with GA4, Hotjar, AB Tasty, VWO, or Mixpanel who builds experiments directly rather than just advising
  • AI-empowered professional who leverages AI tools daily to generate hypotheses, build assets, and accelerate iteration speed

Demonstrate how you've used behavioral science or psychology frameworks in past CRO work, not just technical tools

4

Include examples of using AI tools (like ChatGPT, Midjourney, or analytics AI) to accelerate CRO processes

5

Tailor your portfolio/resume to show 'system rewiring'—not just button testing—with before/after case studies
