Conversation Rate Optimisation Specialist - French fluent

Are you obsessed with turning insights into measurable growth? Do you thrive on transforming friction into flow and data into impact? What if your experiments didn’t just lift conversions but shaped how millions of people grow, learn, and act on their potential? Then you’ll love this.

We’re looking for a CRO Specialist who doesn’t just test buttons, but rewires systems.

At Paradox, we’re building one of the most advanced ecosystems in human transformation, combining behavioral science, technology, and AI to help people defy their limits. We want someone who can ideate, copy, design, and launch experiments directly, speaks both data and design fluently, and leverages AI tools daily to generate hypotheses, build assets, and accelerate iteration speed.

About Paradox

We believe self‑help is broken. Most learning platforms are consumed the same way: generic theories, quick highs, no real change. At Paradox, we believe people deserve more, more than content or motivation. They deserve a system that knows them, adapts, challenges, and grows with them. We make learning meaningful: it changes how you live, think, and create. We blend human, structured, and technological intelligence to create a seamless ecosystem: Paradox OS.

Our Vision

We want to reinvent how people grow, not just build another course or coaching app but the operating system for greatness. Founded by David Laroche, we aim to compete with players like Mindvalley but with sharper vision, grounded protocols, and a relentless focus on meaningful impact.

Your Mission

Turn growth hypotheses into measurable wins that move both business and human transformation forward. If you crave autonomy, experimentation, and direct impact in a fast‑scaling Ed
Tech company, this is where you belong.

Your 5 Key Responsibilities

• Diagnose & Prioritize: Conduct in‑depth funnel analysis across all Paradox touchpoints from landing pages and checkout flows to onboarding journeys and community platforms. Identify friction points and prioritize based on business impact using structured frameworks (PIE, ICE).
• Design & Run Experiments: Plan, implement, and manage A/B and multivariate tests end‑to‑end from hypothesis definition to variant development and post‑test analysis. Collaborate with UX, Dev, and Product teams to deploy clean, validated experiments.
• Analyze & Communicate: Extract actionable insights from analytics dashboards (GA4, Mixpanel, Looker Studio). Present findings with clarity and influence decision‑making at the highest level.
• Optimize User Experience: Combine quantitative data (heatmaps, session recordings, analytics) with qualitative feedback (user tests, surveys) to improve flow, trust, and engagement across key funnels.
• Systemize Growth Learnings: Build and maintain a central CRO knowledge base documenting test hypotheses, outcomes, and learnings. Create templates, SOPs, and playbooks to scale what works.

Tools You’ll Master

GA4, Optibase, Wefblow, Vidalytics, Clarity, Hotjar, Mixpanel, Figma, Looker Studio, VWO, Optimizely, and other tools that help you spot insights others miss.

Experience

• Minimum 3 years in Conversion Rate Optimization, Growth Experimentation, or Performance Marketing, ideally within Saa
  S, e‑commerce, or digital product environments.
• Track record of designing, implementing, and scaling A/B and multivariate tests that have improved revenue, user activation, or conversion.

Personality

• Curiosity: relentlessly dig into why users behave the way they do until you uncover the insight behind the data.
• Precision: care about clarity in hypotheses, clean data, and unambiguous results.
• Agility: move fast, adapt instantly to new findings, and turn insights into tests within hours, not weeks.

Language

• French: Native / Bilingual.
• English: Fluent, able to hold conversations on specific details with English‑speaking colleagues.
• Our chosen language for written communication is English.

It Might Not Be For You

• ❌ If you need clarity before chaos – wrong place.
• ❌ If you prefer balance over intensity – wrong season.
• ❌ If you build to deliver, not to elevate – wrong mission.
• ❌ If you want to optimize without getting your hands dirty in Webflow, copy, or design – wrong role.
