Previously the functionality we currently know as Jobs was known as Careers.
Seeing that most of the questions regarding this topic are off-topic to MSE in the first place, I don't see any value in having them spread out over several tags. The only thing that would be on-topic is the implementation of the jobs link on other technical sites like Super User.
There are also some specific versions of careers: careers-germany careers-city-pages careers-2(a synonym of careers). These can all be grouped together into jobs I think.
