Job description for Senior Full Stack Web Developer at 13-years
The Agency
13 Years is a new-generation creative agency. 70 talents, 25 nationalities, multiple time zones, and a fluid, fast-moving team that never stands still.
We're AI-native. Not as a slogan, as a practice. Every week we test, integrate, and push tools to see how far they can go. Curiosity and boldness guide our decisions.
Our clients include LVMH, Louis Vuitton, Cartier, Moncler, L'Oréal, Sanofi, Stellantis, and BNP Paribas. They work with us to challenge conventions, not repeat them.
Everything here is built on collaboration, shared intelligence, and the desire to create together. The project always comes first, driven by quality, meaning, and the pleasure of making things well.
The Role

We're an AI-native agency and want someone who is comfortable using tools like Claude Code or Codex as part of their workflow. You know how to use AI to move faster while staying responsible for the quality, functionality, and security of what you ship.
Projects are collaborative. You'll work with our creative team to shape ideas, solve problems, and bring concepts to life.
