In Jekins builds can be triggered by simply calling a URL. In Github, it is really easy to add a post receive hook which calls a URL. Just call the build URL, and everytime a branch is pushed, Jenkins will build the project and to other things associated with the task (like deploying to staging, running tests on staging, and deploying to production if the staging tests don't return an error).

There is also a Plugin (https://wiki.jenkins-ci.org/display/JENKINS/Github+Plugin) which should handle this automatically.
