Jenkins + the Job DSL Plugin [0] has been amazing. We don't do any configuration in the web interface, instead everything lives in a groovy file on BitBucket. Every time we push a change Jenkins grabs it and auto runs the groovy file, regenerating all of our jobs. We have it set up so that a job is created for every branch in our repo, so much easier to work with. All a developer has to do to get his branch building is push it to the repo.
