The company for which I work, Tucows, has a job opening for an Integration Engineer. Here's a very quick description of the job:

The successful incumbent candidate will have the challenging opportunity to work on Tucows’ vast and complex high availability system spread across multiple data centers, servers and operating systems. You’ll work with a dynamic team of Integration Engineers to develop, deploy and maintain components of a large scale hosted messaging platform. In addition, you will develop software components for our hosted messaging platform; liaise with third party suppliers in customizing applications for deployment on our high availability production environment; as well as contribute to ongoing process improvement of the SDLC.
