The Free Software Foundation (FSF), a Massachusetts 501(c)(3) charity with a worldwide mission to protect computer user freedom, seeks a contract JavaScript Developer to work on GNU LibreJS, a free browser add-on that addresses the problem of nonfree JavaScript described in Richard Stallman's article The JavaScript Trap. This is a temporary, paid contract opportunity, with specific deliverables, hours, term, and payment to be determined with the selected candidate. We anticipate the contract being approximately 80 hours of full-time work, with the possibility of extension depending on results and project status.

Reporting to our technical team, the contractor will work to implement important missing features in the LibreJS extension. We are looking for someone with experience in backend JavaScript development, WebExtensions, and NodeJS/Browserify. Experience with software licensing is a plus. This is an urgent priority; we are seeking someone who is able to start now. Contractors can be based anywhere, but must be able to attend telephone meetings during Eastern Daylight Time business hours.

Examples of deliverables include, but are not limited to:

Web Labels support, plus Web Labels in JSON format

SPDX support

Unit and functional testing

User interface improvements

New and updated documentation

LibreJS is a critical component of the FSF's campaign for user freedom on the Web, and freeing JavaScript specifically. Building on past contributions, this is an opportunity to help unlock a world where users can better protect their freedom as they browse, and collaborate with each other to make and share modified JavaScript to use.
