Are you obsessed with turning insights into measurable growth?
What if your experiments didn’t just lift conversions but shaped how millions of people grow, learn, and act on their potential?
This isn’t another growth job.
It’s the chance to define a new category : The EcoSystem for Human Greatness Augmented with AI, combining behavioral science,
technology, and AI.
We’re not looking for someone who only advises on what to test, we’re looking for someone who builds it.
A hands-on Growth profile who can ideate, copy, design the strategy and launch experiments directly.
Someone who speaks both data and persuasion fluently, and leverages AI tools daily to generate hypotheses, build assets, and
accelerate iteration speed.
And you deserve it because you are…
wire up an automation, and launch the test by Friday.
🤖 You don't fear AI, you leverage it. Cursor, Claude, n8n/Make, prompt pipelines, AI-generated creatives… you treat AI as a
team of interns that lets you do the work of five people.
⚡️ You'd rather ship a scrappy v1 today than a perfect plan next quarter. Bias to action is your default setting.
📊 You make decisions with data. You can read a cohort chart, smell a vanity metric, and tell the difference between a result
and a coincidence.
You've got 2–3 years under your belt, you're hungry, and you want to walk into a startup and crush it.
Then this job might be for you!
This is a full-time position, carried out remotely or from our beautiful offices in Dubaï.
French and English fluency is required.
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.
To create one seamless ecosystem: Paradox OS.
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, one that 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.
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.
Be the hands-on builder inside the Growth team. You take funnels apart, rebuild them to convert better, and ship the experiments
yourself : copy, landing pages, automations, AI-assisted assets.
1. Build & ship experiments (CRO & A/B Testing) - You design, launch, and analyze A/B tests yourself : headlines, pricing, offers.
You don't wait for a report, you dig into the data to find the winner.
2. Build funnels & assets (Hands-On) - You map funnels and build them: landing pages in Webflow, automations, tracking setup. You
check the flows and make sure the machine works before anything scales.
3. Hunt friction - You proactively look for drop-off points in the user journey. If a page isn't converting, you audit it, propose
a fix, and ship the test immediately with the team.
4. AI leverage - You build prompt pipelines and lightweight automations (Make / n8n / scripts), generate and iterate creatives
with AI, and turn manual grind into background processes.
5. Read the data - You live in GA4, Amplitude, Hotjar, Clarity. You find the insight behind the numbers, kill vanity metrics, and
make sure learnings compound over time.
6. Contribute to channels & growth loops - Alongside the team, you test new acquisition angles and help optimize growth loops
(retention, referral, content → product → content). You bring data-backed briefs to the Content Factory and spot winning angles
fast.
GA4, Optibase, Wefblow, Vidalytics, Clarity, Hotjar, Amplitude, Figma, Looker Studio, VWO, Optimizely, and whatever helps you see

built better relationships, and made positive changes in their lives.
But that's not all, we believe that driven people deserve…
📃 A 6 to 8 minutes application survey.
💻 A 15-30 minutes video call, to assess the fit between the position, the company, and your own career path.
💻 A video-call focused on your career to review your background & see how we can match your desires with our needs.
💻 A culture-fit video call to check in depth the alignment between you and our values and culture.
💼 Reference calls to get in-depth insights about how you work in different environments, make your onboarding easier, and give
everybody on the team the insurance to be surrounded by A-Players.

About Brave Brave is on a mission to protect the human right to privacy online. We’ve built a free web browser that blocks creepy ads and trackers by default, a private search engine with a truly independent index, a private ad network (opt-in!) that directly rewards you for your attention, and a browser-native AI integration focused on keeping private data private. And we’re just getting started. Already 110 million people have switched to Brave for a faster, more private web. Millions more switch every month. The internet is a sea of ads, hackers, and echo chambers. Big Tech makes huge profits off our data, and tells us what’s true and what’s not. Brave is fighting back. Join us! The Browser AI team are building core browser features, and exploring new ideas about how the personal nature of the browser can help create the best AI experience for research and creative tasks. Brave allows the user to attach tabs, history, bookmarks and files to AI conversations. Brave also allows the user to experiment with AI joining in with its own web browsing. We’re looking for a new team member capable of iterating these ideas and creating beautiful user experiences for these features. UI engineers will often work with other engineers to create the end-to-end features, or develop the skills necessary to implement the entire feature themselves. Brave has an exciting UI engineering culture. We share knowledge and patterns across both teams and disciplines, overlapping closely with designers. We work with internal design systems, multiple UI frameworks, and make effective decisions on these features as a team. This role is at an exciting intersection between web UI, web browser internals, and AI possibilities. Brave is a start-up, and we have the ability to change plans quickly in response to new information or circumstances. This means that new needs can emerge on short notice, and projects are often re-mixed and adjusted in response to new input. Successful applicants will have the opportunity to influence those choices and other areas of the team. Many engineers in this role at Brave start from a frontend or full-stack background and grow into browser-level C++ feature work over time. RESPONSIBILITIES WILL INCLUDE: * Implementing browser-integrated Web UI (e.g. AI conversations, browser settings, new tab page) using Typescript, JavaScript, HTML and CSS with React as well as other frameworks such as Web Components, Svelte and Lit * Working with our product development team to collaborate on designs and specs and bring them to life on Brave’s desktop and mobile browsers * Integrating with custom browser APIs using Chromium’s communications frameworks. * Helping to customize the native UI provided by Chromium to add new product features and modify existing features. These UI elements include toolbars, modals, buttons, and more * Delivering code which is well tested with high confidence * Working alongside and learn from our experienced Chromium engineers - helping with peer reviews and helping improve our engineering processes REQUIRED EXPERIENCE: * Strong skills building complex web apps with state management * Deep knowledge of a Javascript UI framework such as React, Svelte, Vue, or native Web Components * Proven expertise with CSS for building UI * Commitment to various UI accessibility and localization techniques * C++ expertise or experience with Chromium is required * Understanding of performance impact and how both to measure and make improvements PREFERRED EXPERIENCE: * Working with and graspine large code repositories * AI coding tools * Knowledge of how LLMs and their associated tools and APIs work WORKING AT BRAVE * Industry-leader in privacy, with a research and engineering team that’s innovating everyday to keep people safer online and beat Big Tech * Highly competitive salaries & benefits, and generous home-office stipends * Fully remote team (no office, no commute) * Minimal meetings * Welcoming, humble, ridiculously smart teammates, and a truly flat org structure * Opportunity to get in early at a hyper-growth company, and revolutionize the web * Oh, and did we mention Brendan, our CEO & co-founder, invented JavaScript?
