Tasks are very varied, from developing core platform features, custom exercises and tools for specific courses (XBlocks), customizing and deploying instances, working fullstack, operating our service infrastructure, improving our hosting platform, etc. You won't get bored here.

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.
