You're not afraid of big styles codebases and have a high sense of organization and structure.
You have strong opinions on how your CSS file should be organized, you like a good design system, where everything has its place, is clear and well documented.


  • HTML (proper knowledge)
  • CSS (SASS)
  • Javascript (enough to understand what's happening)
  • Experience with at least one design system
  • Communication - we like learning from each other!
  • Bonus: experience with React or component-based frameworks (that's what we use now)

Qualifications and practicalities:

  • 3-5 years of relevant experience
  • Good knowledge of French & English
