Are you a front‑end developer fluent in French eager to shape the future of AI?

Large‑scale language models are evolving from chatbots into engineering copilots. With high‑quality training data, AI can democratize software education, keep pace with web standards, and streamline UI development. Your expertise is essential to power this next generation of AI.

We’re seeking front‑end specialists skilled in JavaScript & TypeScript, React, HTML5, CSS3/Tailwind, responsive design, Web Accessibility (WCAG/ARIA), Vue or Angular, state management (Redux/Pinia), build tools (Vite/Webpack), performance optimization, cross-browser compatibility, and testing with Jest or Playwright.

You will evaluate language models on topics like hooks vs. class components, CSS Grid, SVG, internationalization for French markets, progressive web app caching, code-splitting, Lighthouse scores, theming, and CI/CD practices. Documenting failures helps improve model reasoning.

Your role includes conversing with models on coding and front-end questions, verifying accuracy, capturing error traces, and suggesting prompt improvements.

Ideal candidates have a bachelor’s or master’s in computer science or related fields; open-source contributions, React/Vue apps, or UX audits are a plus. Clear, detailed communication is essential.

Ready to leverage your front-end skills to teach the AI of tomorrow? Apply today and help shape the future of technology.
