See edx.org, stanford.edu or fun-mooc.fr for examples of Open edX instances.

Most of your work is published as free software (Open edX is released under the AGPL license, which requires clients to release modifications under the same license), and you would also contribute to the free software project, pushing most of your developments upstream through pull requests, contributing features, documentation or help on mailing-lists.

We welcome applicants of all genders and ethnicities.
