  • You have experience building responsive websites
  • You have experience working on ecommerce sites.

  • Apply before December 7. Tell us in your cover letter why you’d be a great fit.
  • The entire application procedure will be online - you won't have to travel.
  • Know that as part of the process we will give you an assignment to evaluate your skills.

Are you currently working as a freelancer? We understand that you may already have clients or projects of your own, and that is completely fine. Please note that this is a supply-demand job, meaning that some month we will have more work than others, so we need you to be flexible (within reason of course). However, you can count on at least 15 hours of work a week.
