Conversation Rate Optimisation Specialist - French fluent
Join to apply for the role at Paradox EN.
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 not looking for someone who only advises on what to test, we’re looking for someone who builds it. A hands‑on CRO who can ideate, copy, design, and launch experiments directly. Someone who speaks both data and design fluently, and leverages AI tools daily to generate hypotheses, build assets, and accelerate iteration speed. 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’re looking for a CRO Specialist who doesn’t just test buttons, but rewires systems.
* A Conversion Architect, skilled at diagnosing funnel bottlenecks and translating data into structured experimentation roadmaps that deliver measurable business outcomes.
* A Behavioral Strategist, fascinated by what drives human action, able to mix cognitive psychology, UX, and persuasion frameworks to design experiences that convert because they resonate.
* A Data‑driven Creator, fluent in GA4, Hotjar, AB Tasty, VWO, Mixpanel, not just running tests, but connecting insights to revenue, retention, and lifetime value.
This is a full‑time position, carried out remotely or from our beautiful offices in Dubai or Lisbon. French and English fluency is required.
About Paradox
At Paradox, we are convinced that greatness is trainable. That’s why we want to empower people at scale, by leveraging cutting‑edge technologies like AI, and crafting user experiences with outstanding aesthetics.
We do that by merging Human Intelligence (coaches, peers, and mentors), Structured Intelligence (protocols, mental models, rituals), and Technological Intelligence (AI personalization, feedback loops, adaptive journeys) to create one seamless ecosystem: Paradox OS.
OUR BELIEFS: We believe self‑help is broken. Most learning platforms are used the same way: consuming generic theories, getting quick highs, ending with no real change. At Paradox, we believe people deserve more. More than content. More than motivation. They deserve a system that knows them, adapts, challenges, and grows with them. We believe that every human learns differently, and that technology can do more than entertain or save time. It can translate insight into transformation through AI personalization, lean experimentation, and deep psychological understanding. Because learning shouldn’t just make you feel inspired for a day, it should change how you live, think, and create.
OUR VISION: At Paradox, we want to re‑invent how people grow. We do not build another course or coaching app but the Operating System for Greatness. Founded by David Laroche, a creator followed by over 2 million people and known for his interviews with icons like Tony Parker, Mike Horn, Richard Branson, and Gad Elmaleh, Paradox aims to build something that will live beyond any individual (including its founder), for decades to come. Our ambition is to compete with players like Mindvalley (150M ARR), but with a sharper vision, grounded protocols for achievers, people who want more for their life, refusing mediocrity. To do that we bring together designers, tech, coaches, and filmmakers to create learning experiences that are cinematic, precise, and effective. We move fast, aim high, and hold ourselves to the standards of Apple, Spotify, and MasterClass. No fluff, focused on meaningful impact. While others hide their numbers, we want to let our results speak loudly for us. Get obsessed with transforming our clients’ lives and let those transformations be our marketing.
AND THAT’S WHERE YOU COME IN.
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 EdTech company, this is where you belong.
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.

* You have a track record of designing, implementing, and scaling A/B and multivariate tests that have generated measurable improvements in revenue, user activation, or conversion.
Personality
* Curiosity: You relentlessly dig into why users behave the way they do until you uncover the insight behind the data.
* Precision: You care about clarity in hypotheses, clean data, and unambiguous results.
* Agility: You move fast, adapt instantly to new findings, and turn insights into tests within hours, not weeks.
Language
French: Native / Bilingual.
English: Fluent English, you can hold a conversation 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 want to optimise without getting your hands dirty in Webflow, copy, or design — wrong role.
Growth & Ambition
* Being surrounded by A‑players who strive to perform.
Impact & Meaning
* Playing a crucial role in the development of a company whose content and products will be used by millions of people.
* Waking up in the morning feeling like you are making a difference.
Freedom & Well‑Being
* A company culture based on autonomy & accountability.
* Flexible working hours.
* A remote culture from day one with the freedom to work from wherever you want.
* A magnificent office in Dubai, Paris, Lisbon — it feels like home.
