We run this site: http://www.leverageresearch.org/
It's a static site, but it's compiled from templates using http://nanoc.ws/, which is written in Ruby, so you need to have a working Ruby / bundler environment set up.
Most of the changes we need made to the site are to the design and the text, so HTML and CSS skills are also important.
We share code via GitHub, and we can't afford to waste time teaching you how to use git.
If you want to apply to this job, please put the name of the city where Leverage is based in your job application. If you don't, we will assume you are a spammer.
We need the changes to go live by the end of this week (Friday 12th July), so only apply if you can start straight away.
